Solution Overview
Problem
Conventional engineering design and manufacturing processes are inefficient, costly, and cumbersome due to limited information on manufacturing costs and times, cultural barriers, and inability to accurately assess manufacturer quality, leading to increased costs and decreased quality.
Innovation Solution
A computer-based design system that provides dynamically updated information to designers, allowing them to interact with multiple manufacturers, receive accurate cost and lead time estimates, and modify designs based on manufacturer-specific capabilities, using a database of manufacturing information and a cost estimation module to generate binding quotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional design processes are used with limited manufacturer information, then designers can complete the design process, but cost and time estimates are inaccurate and competition among manufacturers is reduced
Solution Approach 1:
The system performs preliminary actions by pre-collecting and storing manufacturing capability data, cost structures, and lead time information from multiple manufacturers in a database before the design process begins. This allows the cost estimation module to quickly generate accurate estimates without time-consuming manual negotiations or prototype shop consultations during the actual design process.
Solution Approach 2:
The system implements feedback by providing designers with real-time cost estimates and lead time projections based on manufacturer-specific data. This feedback loop allows designers to adjust designs to optimize for cost or time constraints while automatically updating manufacturer recommendations based on the feedback received from design modifications and selection decisions.
2Extent of automation
If generalized manufacturing rules are applied to cost factors, then automated cost estimation is achieved, but manufacturer-specific variances and capabilities cannot be accounted for
Solution Approach 1:
The system applies local quality by transitioning from uniform generalized manufacturing rules to manufacturer-specific cost models and capability profiles. Each manufacturer in the database has customized cost structures, capability parameters, and pricing models that reflect their unique operations, allowing the cost estimation module to select and apply the appropriate local manufacturer data rather than generic industry averages.
Solution Approach 2:
The system performs preliminary actions by pre-collecting and storing manufacturer-specific cost data, capability information, and pricing structures in the database before the design process begins. This allows the cost estimation module to quickly apply accurate manufacturer-specific rules rather than relying on generalized manufacturing rules during the actual estimation process.
3Reliability
If prototype machine shops are used to finalize component design, then manufacturing feasibility is improved, but costs increase and high volume manufacturing cost indications are not provided
Solution Approach 1:
The system uses copying by creating virtual representations of manufacturer capabilities and cost structures in the database, allowing designers to simulate and evaluate manufacturing feasibility through computer-based cost estimation before committing to physical prototype shops. The cost estimation module generates virtual cost models that mirror actual manufacturer pricing and capabilities, enabling feasibility assessment without physical prototyping expenses.
Solution Approach 2:
The system introduces an intermediary layer between design and physical manufacturing by implementing a computer-based cost estimation and manufacturer matching system. This intermediary provides manufacturing feasibility assessment and cost indication through automated calculations based on manufacturer-specific data, serving as a bridge that reduces the need for expensive physical prototype shop consultations while maintaining reliability.
4Reliability
If the process of finding qualified manufacturers involves word-of-mouth or costly searches, then potential candidates are identified, but the process is inefficient and competition is lessened
Solution Approach 1:
The system applies universality by creating a multi-functional manufacturer database that serves multiple purposes: storing capability information, enabling cost estimation, providing lead time projections, and facilitating manufacturer comparison. This universal database structure allows the system to perform all manufacturer evaluation functions through a single integrated platform rather than requiring separate search, evaluation, and negotiation processes.
Solution Approach 2:
The system implements feedback by automatically updating manufacturer recommendations and rankings based on design requirements, cost constraints, and selection history. As designers interact with the system and provide feedback on their preferences and requirements, the manufacturer matching algorithm adapts to provide increasingly accurate and relevant manufacturer suggestions, reducing search time while maintaining quality.
