Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a resin protector is used as the route holding portion, then the route holding function is achieved, but the manufacturing cost increases due to expensive molds and the lead time increases
Solution Approach 1:
The invention extracts the route holding function from the dedicated resin protector and transfers it to the outer member itself by forming a route holding portion directly on the outer member. This eliminates the need for a separate resin protector component, thereby reducing manufacturing complexity and lead time while maintaining the route holding function.
Solution Approach 2:
The invention merges the route holding function with the outer member by forming an integrated route holding portion. Instead of using separate components (outer member + resin protector), the route holding capability is combined into the outer member structure itself, reducing the number of parts and assembly steps.
2Ease of manufacture
If a resin protector is used as the route holding portion, then the route holding function is achieved, but the manufacturing cost increases due to mold depreciation in small quantity production
Solution Approach 1:
The invention extracts the route holding function from the dedicated resin protector and transfers it to the outer member itself by forming a route holding portion directly on the outer member. This eliminates the need for a separate resin protector component, thereby reducing manufacturing complexity and lead time while maintaining the route holding function.
Solution Approach 2:
The outer member is designed to serve multiple functions: it provides mechanical protection for the conductive path, enables electromagnetic shielding, and holds the route configuration. By making the outer member multi-functional, the invention eliminates the need for separate dedicated components like resin protectors, reducing overall manufacturing cost especially in small quantity production.
3Ease of manufacture
If a resin protector is used as the route holding portion, then the route holding function is achieved, but the design flexibility decreases due to cumbersome design changes
Solution Approach 1:
The invention merges the route holding function with the outer member by forming an integrated route holding portion. Instead of using separate components (outer member + resin protector), the route holding capability is combined into the outer member structure itself, reducing the number of parts and assembly steps.
Solution Approach 2:
The route holding portion is formed with elastic deformability, allowing it to be dynamically adjusted during assembly. The portion can be elastically deformed to accommodate different conductive path configurations and then maintains the desired shape, providing design flexibility without requiring complete redesign of separate components.
