Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power supply unit is fixed in a specific direction and position, then the structure is simple and easy to manufacture, but the layout versatility and adaptability to different specifications are poor
Solution Approach 1:
The power supply member is designed with a universal structure that can accommodate multiple orientations and positions of the connector connecting part through the provision of multiple concave parts on the cases. This allows a single power supply member design to serve multiple layout configurations, improving adaptability without requiring multiple specialized components for different specifications.
Solution Approach 2:
The cases are divided with multiple concave parts positioned at different locations and orientations. This segmentation allows the connector connecting part to be positioned in various directions (e.g., radially outward, axially outward) while maintaining a unified power supply member structure, thus achieving layout versatility without increasing overall structural complexity.
2Adaptability or versatility
If multiple shapes of brush holders and gear housings are prepared to diversify power supply unit positions, then layout versatility is improved, but manufacturing complexity increases and yield deteriorates
Solution Approach 1:
Instead of preparing multiple specialized brush holder and gear housing shapes for different power supply unit positions, the invention uses a single universal power supply member design that can be adapted to various positions through the concave part configuration on the cases. This reduces the number of unique components that need to be manufactured, thereby improving manufacturing yield while maintaining position diversity.
Solution Approach 2:
The design allows for flexible positioning of the connector connecting part by utilizing the predetermined concave parts on the cases rather than requiring different rigid component shapes. This dynamic adaptability enables a single power supply member to serve multiple configuration needs, reducing manufacturing complexity and improving yield.
3Adaptability or versatility
If the connector connecting part is positioned in various directions to improve layout properties, then adaptability increases, but the number of component variations increases
Solution Approach 1:
The power supply member is designed as a universal component that can accommodate connector connecting parts in various directions (radial, axial, etc.) through the provision of multiple concave parts on the cases. This single universal design reduces the need for multiple specialized component variations while maintaining high adaptability for different layout requirements.
Solution Approach 2:
The cases incorporate concave parts with asymmetric positioning and orientations to accommodate the connector connecting part in various directions. This asymmetric design allows a single power supply member to adapt to different connector positions without requiring symmetric variations of the component itself, thereby reducing overall component variations.

AI summary
A power supply member 50 is provided with a convex part 60 that fits into either of a pair of cutout parts provided in a gear case, thereby positioning a connector connecting part 52 with respect to the gear case and a motor yoke along a circumferential direction of a rotating body. Thus, with a single power supply member 50 it is possible to form a seat motor with various specifications (disposition mode A and disposition mode B) wherein the protrusion direction of the connector connecting part 52 differs. Accordingly, the layout property can be improved, versatility can be increased, and yield can be improved.
