Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If plastic covers are glued, clipped or screwed into the metallic main body of the vehicle wheel for aerodynamic reasons, then the aerodynamic performance is improved, but the flexibility of color design is limited and replacement costs are high
Solution Approach 1:
The patent applies color change technology by integrating an electrophoretic display element into the cover element, allowing the color and design of the wheel cover to be dynamically changed through electrical signals. This enables users to switch between different colors and patterns without physical replacement, directly resolving the contradiction between maintaining aerodynamic performance and achieving design flexibility.
Solution Approach 2:
The patent changes the operational parameters of the cover element by incorporating an electrophoretic display that can be controlled via electrical signals. The display element can switch between different states (colors, patterns) by applying voltage, allowing the same physical cover to呈现 multiple designs, thus achieving adaptability while maintaining the original aerodynamic structure.
2Adaptability or versatility
If new cover elements are purchased and replaced to change the design of the wheels, then the design flexibility is improved, but the cost increases and time is consumed
Solution Approach 1:
The electrophoretic display element enables instant color and design changes through electrical control, eliminating the time-consuming process of physically replacing cover elements. Users can switch designs in seconds by sending control signals, directly addressing the time loss issue while maintaining full design flexibility.
Solution Approach 2:
The patent replaces the mechanical replacement system (physically removing and installing new covers) with an electrical control system. The electrophoretic display responds to electrical signals to change appearance, substituting mechanical operations with electrical ones, thereby eliminating replacement time while preserving design adaptability.
3Adaptability or versatility
If a cover element with display device is used to enable design changes, then the flexibility is improved, but the device complexity increases
Solution Approach 1:
The cover element is designed with multi-functionality by integrating both the aerodynamic cover function and the electrophoretic display function into a single component. This universal design allows the cover to serve dual purposes: maintaining wheel aerodynamics and providing customizable visual display, thereby achieving high adaptability without proportionally increasing overall system complexity.
Solution Approach 2:
The patent merges the cover element structure with the electrophoretic display device into an integrated unit. The display element is incorporated within the cover, combining two previously separate functions (aerodynamic coverage and visual customization) into one component, which optimizes the complexity-benefit ratio by reducing the number of separate parts.
