Solution Overview
Problem
Existing motor adapters for vehicle seat adjustment devices face challenges in providing secure, reliable, and easy-to-assemble connections while accommodating component tolerances and limited installation spaces, with complex tools often required for maintenance and assembly.
Innovation Solution
A motor adapter with a motor mount and coupling mount configured for form-fit and force-fit connections, allowing direct coupling to the motor and compensation for component tolerances, and featuring a compact design with integrated damping sections for vibration reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor adapter with separate motor mount and coupling mount is used, then the connection reliability between motor and coupling is improved, but the device complexity increases
Solution Approach 1:
The motor mount and coupling mount are merged into a single integrated motor adapter component. The adapter features a motor mount opening for receiving the motor and a coupling mount opening for receiving the coupling, both formed in one piece. This integration maintains reliable form-fit and force-fit connections while eliminating the complexity of separate mounting components.
Solution Approach 2:
The motor adapter serves multiple functions simultaneously: it provides a mounting interface for the motor, a mounting interface for the coupling, and structural support for the entire assembly. The single adapter component replaces what would otherwise require multiple separate parts, reducing overall device complexity while maintaining connection reliability.
2Reliability
If direct coupling of motor and coupling is implemented, then torque transmission reliability is improved, but the adaptability to component tolerances deteriorates
Solution Approach 1:
The motor adapter acts as an intermediary component between the motor and the coupling. It provides mounting openings that accommodate both components while allowing for tolerance compensation through the adapter's own dimensional tolerances and mounting geometry, enabling direct coupling without requiring precision alignment or flexible transmission elements.
3Volume of moving object
If compact motor adapter design is used, then the installation space requirement is reduced, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The motor adapter is designed as a segmented structure with distinct motor mount opening and coupling mount opening regions. This segmentation allows for modular assembly where the motor and coupling can be independently positioned and secured, facilitating easy assembly and disassembly despite the compact integrated form factor.
4Strength
If form-fit and force-fit connection is used, then the connection strength is improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The form-fit and force-fit connection features are integrated into the motor adapter as built-in structural elements rather than separate fastening components. The adapter's mounting openings incorporate these connection features directly, providing strong connections that can be assembled and disassembled using simple tools, thereby maintaining ease of repair despite the strong connection requirement.

AI summary
A motor adapter may have on the one hand, a motor mount and, on the other hand, a coupling mount. The motor mount may be configured as a first mount opening that is designed to receive a motor and to hold the motor releasably in a form-fit and/or force-fit manner. The coupling mount adjoins the motor mount and is configured as a second mount opening which may be designed to receive a coupling and to hold it releasably in a form-fit and/or force-fit manner. The coupling may be joined directly to the motor.
