Vehicle Power Seat Switch Module with Directional Touch Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power seat switch modules in vehicles fail to accurately guide the operating direction of power seats, leading to user discomfort due to the display of multiple arrows for each switch operation, which confuses the intended direction and increases operational complexity.
Innovation Solution
A device with a switch module incorporating multiple touch sensors embedded in push button switches and a main controller that displays a single arrow on a display to guide the operating direction of the power seat, allowing users to accurately recognize the intended operation of the switch and the power seat's direction while maintaining their focus on the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple arrows are displayed for each switch operation to show all possible operating directions, then the information completeness is improved, but the device complexity and ease of operation deteriorate due to user confusion and increased operational complexity
Solution Approach 1:
The patent applies local quality by making different parts of the switch module have different functions. Specifically, different regions of the same switch are divided into multiple touch sensor areas, each corresponding to a specific operating direction. When a user touches a particular region, only the arrow corresponding to that region is displayed, providing localized and context-relevant information rather than overwhelming the user with all possible directions at once.
Solution Approach 2:
The patent segments the switch operation into multiple discrete touch sensor areas within a single switch. Each touch sensor area is associated with a specific operating direction, allowing the system to divide the information display into manageable segments based on user input location. This segmentation resolves the contradiction by showing only the necessary information segment rather than the complete set of all possible directions.
2Loss of information
If multiple arrows are displayed to guide all possible operating directions, then the guidance completeness is improved, but the device complexity increases due to multiple display elements and control logic
Solution Approach 1:
The patent applies dynamics by making the display content dynamic and adaptive based on user interaction. Instead of statically displaying all possible operating directions simultaneously, the system dynamically adjusts the displayed arrows based on which touch sensor area is activated. This dynamic approach maintains guidance completeness by showing all directions when needed while reducing complexity by displaying only relevant directions during operation.
Solution Approach 2:
The patent implements feedback by using touch sensors to detect user input location and providing visual feedback through selective arrow display. The system monitors which region of the switch is touched and responds by displaying only the corresponding operating direction arrow, creating a feedback loop that reduces information overload while maintaining complete guidance capability through iterative interaction.
3Measurement precision
If touch sensors are embedded in each switch region to detect precise touch location, then the measurement precision is improved, but the device complexity and manufacturing precision requirements increase
Solution Approach 1:
The patent applies universality by using a single switch structure that serves multiple functions through embedded touch sensors. Rather than creating separate physical switches for each operating direction, the system uses one switch with multiple touch-sensitive regions, each capable of detecting different touch locations. This multi-functional approach achieves high measurement precision for touch location while avoiding the complexity of multiple separate switch mechanisms.
