Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a metal plate mounting member is used with adhesive bonding, then the wiper can be manufactured with traditional processes, but the manufacturing process becomes complex with multiple steps including cutting, degreasing, strain elimination, burr polishing, and adhesive application
Solution Approach 1:
The patent combines the mounting member and wiper body into a single integrally molded elastic member. The mounting member is formed as an integral part of the wiper body through injection molding, eliminating the need for separate metal plate fabrication, adhesive application, and assembly processes. This merging of components directly reduces the number of manufacturing steps while maintaining mounting functionality.
Solution Approach 2:
The patent changes the material parameter from metal plate to elastic material for the mounting member. By using an elastic material that can be injection molded, the mounting member can be integrally formed with the wiper body, transforming a multi-step mechanical assembly process into a single molding operation. This parameter change enables the integration of previously separate components.
2Reliability
If different materials are used for the wiper body and sliding part, then each part can have optimized properties, but the joining between parts requires adhesive bonding which adds manufacturing complexity
Solution Approach 1:
The patent merges the wiper body and sliding part into a single integrally molded component. The injection molding process forms both parts in one operation, eliminating the need for adhesive bonding or other joining methods. The integral structure ensures strong joining while simplifying manufacturing by removing separate assembly steps.
Solution Approach 2:
The patent uses a composite elastic material formulation that allows different regions of the molded part to have different properties. The sliding part contains particulate reinforcing material for enhanced sliding performance, while the wiper body has different formulation for its specific function. Both regions are formed in a single injection molding process, achieving material differentiation without separate assembly.
3Strength
If a metal plate is used for the mounting member, then structural strength is achieved, but pretreatment work such as cutting, degreasing, strain elimination, and burr polishing is required
Solution Approach 1:
The patent changes the material from metal plate to elastic material for the mounting member. This parameter change enables the use of injection molding, which forms the mounting member in a single process without requiring cutting, degreasing, strain elimination, or burr polishing operations. The elastic material provides sufficient strength for mounting while enabling simpler manufacturing.
Solution Approach 2:
The patent extracts the mounting member from the category of metal components requiring traditional metalworking processes. By using elastic material that can be injection molded, the mounting member is taken out of the metal fabrication process chain, eliminating multiple pretreatment and finishing steps while maintaining structural functionality.
