Seesaw Switch Module for Vehicle Power Seat Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power seat operating systems for vehicles are inconvenient as they display all possible operation directions simultaneously when a user touches a switch, leading to confusion and increased difficulty in accurately guiding the user to the desired operation direction.
Innovation Solution
The implementation of a power seat operating device with a seesaw type switch module that embeds multiple touch sensors for each switch, allowing the main controller to determine and display only the relevant operation direction on a display, thereby guiding the user accurately to the desired switch and seat operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all possible operation directions are displayed simultaneously when a user touches a switch, then the user can see all available options, but the user becomes confused and has difficulty accurately identifying the desired operation direction
Solution Approach 1:
The display information is segmented into multiple categories: selected switch identification, selected operation direction, and unselected operation directions. This segmentation allows the system to present comprehensive information while organizing it in a way that highlights the most relevant details and reduces user confusion through structured presentation.
Solution Approach 2:
Different visual qualities are applied to different parts of the display information. The selected operation direction receives prominent visual treatment (such as enhanced brightness, color, or size), while unselected directions are displayed with reduced visual emphasis. This local quality differentiation guides user attention to the most important information without completely hiding other options.
2Measurement precision
If multiple touch sensors are embedded in each switch to detect operation direction, then the system can accurately determine the user's intended direction, but the switch module complexity increases
Solution Approach 1:
Each touch sensor is designed to serve multiple functions: it can detect touches from different directions (up, down, left, right), determine the magnitude of the touch, and identify which switch is being operated. This multi-functionality reduces the need for separate sensors for each detection task, thereby managing complexity while maintaining high measurement precision.
Solution Approach 2:
The system transitions from detecting simple touch presence to detecting touch direction and magnitude by analyzing signals from multiple sensors simultaneously. By adding the dimension of directional detection through sensor arrays, the system achieves precise operation direction identification without requiring completely separate detection mechanisms for each direction.
3Ease of operation
If the display shows only the selected operation direction, then the user can easily recognize the intended operation, but the user loses visibility of other available operation options
Solution Approach 1:
The display dynamically adjusts its presentation based on the user's selection. When a switch is touched, the display transitions from showing all possible operations to emphasizing the selected operation direction while maintaining visibility of unselected options. This dynamic adaptation ensures that the most relevant information is always prominent while preserving access to complete operational context.
Solution Approach 2:
The system provides immediate visual feedback when a user touches a switch, updating the display to reflect the selected operation direction. This feedback mechanism confirms the user's input and guides them toward the intended operation while still allowing them to see alternative options if they wish to change their selection, creating an interactive information presentation system.

AI summary
A power seat operating device for a vehicle has a switch module for operating a power seat of the vehicle. In particular, the switch module includes a plurality of seesaw type switches to control operation directions of the power seat, and the operation directions of the power seat according to the operation of each switch is displayed with arrows on a display, thereby improving the switch operating convenience of the user such as accurately controlling the operation direction of the power seat according to the switch operation by the user, and accurately recognizing a selection state and an operation direction of the switch desired by the user.
