Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the motor mount and adapters are both made of metallic material, then structural strength is improved, but metallic noise and vibration increase
Solution Approach 1:
The patent applies composite materials by combining metallic motor mount with non-metallic adapters made of plastic or polymer materials. This composite construction allows the motor mount to provide structural strength while the non-metallic adapters reduce metallic noise and vibration at the interface between the motor mount and seat rails.
2Reliability
If screw connections are used to fasten the motor mount to seat rails, then connection reliability is improved, but assembly complexity and transportation efficiency worsen
Solution Approach 1:
The patent replaces the traditional screw connection mechanical system with a clip-based fastening system. The clips engage with corresponding features on the seat rails to secure the motor mount, eliminating the need for screws and simplifying both assembly and transportation while maintaining connection reliability.
3Stability of the object's composition
If the motor mount is directly fastened to seat rails, then structural rigidity is improved, but acoustic performance and vibration decoupling worsen
Solution Approach 1:
The patent introduces non-metallic adapters as intermediary elements between the motor mount and seat rails. These adapters serve as mediators that maintain the structural connection while providing acoustic optimization and vibration decoupling, thus protecting the system from harmful vibrations while preserving structural rigidity.

AI summary
The invention relates to an adjusting device (100, 200) for a vehicle seat, comprising a first adjustable assembly (20), a second adjustable assembly (22), and an electric motor (24). The electric motor (24) is operatively connected both to an adjustment gearing (32) of the first adjustable assembly (20) as well as to an adjustment gearing (32) of the second adjustable assembly (22) by means of at least one output shaft (36). A motor support (110, 210) is provided which receives the electric motor (24), and the motor support (110, 210) is secured to the two adjustable assemblies (20, 22) by means of a respective adapter (120, 220). The motor support (110, 210) is made of a metal material as a single piece, and the adapters (120, 220) are made of a non-metal material. The invention additionally relates to a method for assembling an adjusting device (100, 200) according to the invention. The adapters (120, 220) are first secured to the respective paired adjustable assembly (20, 22), and the engine support (110, 210) is connected to the adapters (120, 220) in an additional method step.
