Solution Overview
Problem
The implementation of various seat control functions in vehicles requires a multitude of motors and switching elements, leading to increased cost, weight, and package size due to the extensive wiring needed to power these components.
Innovation Solution
The seat control device shares switching elements among multiple motors, reducing the number of required elements and wiring by connecting motors in series or forming groups, and utilizing a driving table to optimize motor operation based on simultaneous input signals and memory seat positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors and switching elements are provided to implement various seat control functions, then seat control functionality is improved, but device complexity and cost increase
Solution Approach 1:
Each switching element is designed to perform multiple functions by controlling different motors at different times. The switching elements are reused across multiple motors rather than being dedicated to single motors, allowing the same switching element to control motor A at one time and motor B at another time, thereby reducing the total number of switching elements required.
Solution Approach 2:
The patent combines the control functions of multiple motors into a shared switching element system. By merging the switching elements into a common pool that serves multiple motors, the system reduces redundancy and consolidates components, achieving lower device complexity while maintaining full seat control functionality.
2Adaptability or versatility
If multiple motors and switching elements are provided to implement various seat control functions, then seat control functionality is improved, but cost increases
Solution Approach 1:
Switching elements are designed as universal components that can control any motor in the system, eliminating the need for dedicated switching elements for each motor. This universality reduces component count and manufacturing cost while preserving full seat control functionality.
Solution Approach 2:
The patent merges previously separate switching element allocations into a shared resource pool, reducing total component count and associated manufacturing costs. The consolidated approach maintains functionality while lowering production expenses.
3Adaptability or versatility
If multiple motors and switching elements are provided to implement various seat control functions, then seat control functionality is improved, but weight increases
Solution Approach 1:
The switching elements serve multiple motors universally, reducing the total number of switching elements required. This reduction directly decreases the weight of the seat control system while maintaining complete functionality for all seat control operations.
Solution Approach 2:
By merging the switching element assignments into a shared system, the patent eliminates redundant components and reduces overall system weight. The consolidated architecture achieves the same functional output with less physical mass.
4Adaptability or versatility
If multiple motors and switching elements are provided to implement various seat control functions, then seat control functionality is improved, but package size increases
Solution Approach 1:
The universal switching elements reduce the total component count required for seat control functionality. Fewer components mean reduced package size and volume, allowing the same functional capabilities to be achieved in a more compact form factor.
Solution Approach 2:
The patent merges previously separate switching element circuits into a shared configuration, consolidating space requirements and reducing the overall package volume of the seat control system while maintaining full functionality.
