A STRATEGIC APPROACH IN PRODUCT DESIGN
Modern technology is having a profound effect (hoàn toàn hiệu quả) not only on the materials that can be employed, but also on the scale of production and the locations in which manufacturing can now take place. To an extend, this relies (nhờ vào) on designers being able to control both the design and the means of production. The information is, for each process (quá trình; quy trình), broken down under the following subjects: Volumes (khối lượng) of production – Unit prices vs capital investment (vốn đầu tư) – Speed – Surface – Types and complexity of shape – Scale (tỷ lệ) – Tolerances (kích cỡ, khối lượng.. của một bộ phận có thể dao động mà không gây tác hại) – Relevant (thích đáng) Materials – Typical (tiêu biểu, điển hình) applications – Similar methods. As with any specialist field, the world of manufacturing has its own unique vocabulary with a huge list of descriptions specific to particular areas of manufacturing.
A strategic approach to product development to design in quality. The basic approach to product design and development to meet customer needs, quality expectations, competitive price, reduction of product design cycle time, and minimize disuptive design changes can be effectively produced with a well planned process.
Achieving Design to Cost Objective: Target costing for a new product comes from decisions made during the design phase as the designers are drafting blueprints for engineers to evaluate. This approach will map out what the product will be like, how it will work, what features it will have and how it will be manufactured. Suppliers are also well-integrated into the development process to ensure that you're producing the best product for the lowest prive possible.
Building Quality Into Product Design: If quality is not assured by the initial design, then expensive change orders will have to be carried out, wasting valuable engineering resources and possibly including further quality probles in the process. Optimize tolerances for a robust design using GD&T to ensure the high quality by design. This is a systematic way to optimize tolerances to achieve high quality at low cost. The procedure can identify critical dimensions that need tight tolerances and precision parts, which can then be toleranced methodically. This approach can minimize cost while assuring high quality by identifying low demand dimensions that can have looser tolerances and cheaper parts. Simplify the design for the fewest parts, interfaces, process steps, and uncomplicated manufacturing with automated processing result in inherently hight quality products.
Design for Reliability: Design against failure is to understand the failure (why, where, how long, application, etc.). Reliability, and reducing the stress that cause failure can be achieved by material selecting, packaging geometry, and dimensioning modification.
Dependability: Collecting data and recording results.
Time-to-Market: Use of modular design approaches. Sufficient resources to undertake development processes underway. Continuous surveillance of the marketplace and understanding of customer needs. Well-defined development processes based on tightly integrated design automation tools. Well-planned and managed programs with clear definition and acceptance of responsibilities. Process equipment to handle a wide range of work envelopes; FMS; quick set-up and changeover.
Innovativeness: Using measuring and diagnostic equipment; make calculations and estimates and report on findings.
Technology: A technology plan and roadmap based on the business and product strategy and plan. Effective technology management. Process to review new technologies developed outside for applicability internally. Effective process to deploy n ew technology to development programs. State-of-the-art design and analysis tools to support requirements of new technology. Policies to invest in training and development of personnel to master new technology. Culture open to new ideas and taking risks. Investment in new process technology.
PRODUCT DEVELOPMENT & THE APPROACHING PROCESS
Phase I: The Objectives.
This is where the idea for the new product is generated (preliminary design, conceptual design, or functional design) and documented. In this objective phase, inventor shares their original idea as designer collect and learn as much as possible about the conceptual idea. If a 3D model is required, designer will sign a non-disclosure agreement with the inventor to keep the conceptual design discussed confidential. At this early stage designer would deliver a proposal with a firm quote to build the 3D model to help the project engineer decide whether the design will invlove an electrical, mechanical, or software solution that can be incorporated into the design, and whether the product will be designed from the ground up or synthesized from off-the-shelf components.
Phase II: Design Strategy.
Design modeling is where, hired dessigner creates the 3D model based on the concelptual idea and the specifications agreed upon in phase I. The work is summarized and presented to the client so the inventor can make changes to the product with the confidence that the design will work before proceeding to detailing the parts and creating engineering drawings and documents. Included within this phase are assembly verification, component design, and electro/mechanical design, it should be very clear to all engineers/designers what the final product will look like and what its features will be. If, after the review, the project engineer believes parts of the design need to be improved or decide they want modification or new features added, this will be incorporated into the next phase. An update proposal with a new quote for the next phase is submit to the client before proceeding.
Phase III: Product Development.
Detail drafting is where designer modify the presented 3D model for detailing and creating manufacturing drawings and documents of the approved design presented at phase II. Any changes or modifications to the design requested by the engineer at Phase II Review are also incorporated before manufacturing drawings are made. Once drawings and necessary documents are completed, We will send them out to local sub-contractors or manufacturers specified/prefered by project manager for quote so that we all have an estimated price for the building of the product. A written report is summarized and detailing everything done in phase III with the approved changes in phase II. At the end of this phase the costs for a prototype build is submit before proceeding.
Phase IV: Prototype Build.
Approved by project manager, all the parts/hardwares to build the prototype are ordered, received and the product is assembled. Any faults in the assembly process are checked out and inspected. Also, the initial manufacturing procedures are recorded and necessary manufacturing documentation and BOM is created, then a fully built prototypes would be delivered to the customer. Special assembly tools or larger volume assemblies may also require custom design tools to do fine tunes, alignments or to just speed up the assembly process. This would also be addressed here with an update proposal with the cost for special tool design and build before proceeding.
Phase V: Production Launch.
In this stage, the process listed above is repeated to eliminated product issues were discovered in testing. Also this is where DFM (Design for Manufacturing), DFA (Design for Assembly), and DFW (Design for Warranty with Cost Reduction) can be achieve at the highest level as several prototypes are being build and tested to get the final imperfections out of the design as production is ready for the initial product launch. Biotech PackagingThe goal of this release phase is to create a short run of prototypes that are as close to the prototype release as possible and get them into the hands of key quality engineers, selected customers to do their final testing, and ensuring that the subsystems function together as a system at production launch. The production launch phase is usually just to get the final imperfections out of the design as production is ramped up for the initial product launch.
The most critical time in designing a mechanical system for cost saving and improving product performance comes at the very beginning of the design process. Without a good, well thought through base design, the rest of project quickly becomes costly and can result in huge issues that result in poor product performance.
