Integrated Vehicle Seat Control PCB for Space-Saving Multi-Function Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle seats have separate control devices for motorized adjustment, electrical heating, and pneumatic adjustment, leading to limited installation space and inconvenient operation due to the lack of integration with vehicle electronics.
Innovation Solution
A compact seat control device integrating an electric adjustment motor, electric heating device, fluid valve, fluid pump, and control elements on a common circuit board, allowing for single-device control of both electrical and pneumatic adjustments, eliminating the need for additional rocker switches and reducing hose and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate control devices are used for motorized adjustment, electrical heating, and pneumatic adjustment, then each control function can be independently implemented, but the installation space is limited and device complexity increases
Solution Approach 1:
The patent combines multiple control functions (motorized adjustment, electrical heating, and pneumatic adjustment) into a single integrated control device. The circuit board hosts all control elements, valves, and pumps in one consolidated unit, eliminating the need for separate control devices and reducing overall system complexity while maintaining full functional versatility
Solution Approach 2:
The single control device is designed to perform multiple functions simultaneously - it controls both electrical components (motors, heating elements) and pneumatic components (valves, pumps) through a unified circuit board architecture. This multi-functional design allows one device to replace what would traditionally require three separate control systems
2Adaptability or versatility
If separate control devices are used for each seat function, then each function can be controlled independently, but the installation space required increases
Solution Approach 1:
All control components for different seat functions are merged into a single compact control device mounted on one circuit board. This consolidation dramatically reduces the total installation space required compared to having separate control devices for motorized adjustment, electrical heating, and pneumatic adjustment
Solution Approach 2:
The patent transitions from a distributed three-dimensional arrangement of separate control devices to a two-dimensional integrated layout on a circuit board. This dimensional reorganization allows multiple control functions to coexist in a compact planar space, significantly reducing the overall volume required for installation
3Ease of operation
If pneumatic adjustment device is not integrated into vehicle electronics, then pneumatic components can be independently controlled, but convenient operation is not possible and additional rocker switches are required
Solution Approach 1:
The control elements for pneumatic adjustment are merged with those for electrical functions on a single circuit board, allowing all seat adjustments to be controlled through one unified interface. This integration eliminates the need for separate rocker switches and enables convenient operation through the vehicle's existing electronic control systems
Solution Approach 2:
The unified control device provides universal control capability for all seat functions through a single interface. The circuit board integrates control logic for both electrical and pneumatic systems, allowing the driver to operate all adjustment functions through consistent electronic controls rather than mixed mechanical and electronic interfaces
