Vehicle Touchscreen Layout for Seat-Side Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing onboard adjustment input devices for vehicle temperature adjustment have low manipulability when a user is seated, as the contact temperature adjustment input screen image is positioned centrally on the display, making it difficult for users to input commands while seated.
Innovation Solution
A display control method that outputs first and second control commands to a touch-panel display, allowing manipulation from both the right and left seats, with seat-specific settings screens positioned closer to the respective seats, enhancing manipulability by ensuring icons and settings are easily accessible from the user's seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the contact temperature adjustment input screen image is positioned at the center of the display surface, then the display layout is symmetric and standardized, but the manipulability deteriorates when a user is seated in a seat
Solution Approach 1:
The patent applies local quality by positioning the settings screen image at different locations depending on which seat is selected. When the right seat is selected, the screen is positioned at the right side; when the left seat is selected, it is positioned at the left side. This makes each part of the display optimized for its specific use case, improving manipulability for seated users while maintaining a standardized overall layout structure.
Solution Approach 2:
The patent implements dynamics by making the display layout changeable based on user interaction. The settings screen image dynamically repositions itself according to the selected seat, transitioning from a fixed center position to a dynamic position that adapts to the user's seating location. This resolves the contradiction by allowing the layout to be flexible rather than static.
2Ease of operation
If the settings screen image is positioned closer to one seat than the other, then manipulability for that seat is improved, but the display layout becomes asymmetric
Solution Approach 1:
The patent deliberately introduces asymmetry into the display layout based on the selected seat. Instead of maintaining symmetric positioning, the settings screen is positioned asymmetrically closer to the selected seat (right or left). This controlled asymmetry improves manipulability for the seated user while the overall home screen layout remains symmetric and standardized.
Solution Approach 2:
The asymmetric positioning is dynamic rather than fixed. The layout maintains symmetry in its default state but becomes asymmetric when a seat is selected, allowing the system to adapt to user needs while preserving the stable, symmetric structure of the overall display framework.
3Adaptability or versatility
If the display is positioned to be accessible from both seats, then versatility is improved, but the specific manipulability for each seat deteriorates
Solution Approach 1:
The patent segments the display functionality by creating separate icon regions for the right seat and left seat on the home screen. Each seat has its own dedicated area, allowing users to easily identify and access their specific seat controls. This segmentation maintains versatility for both seats while improving seat-specific manipulability through clear spatial separation.
Solution Approach 2:
The patent applies local quality by optimizing different regions of the display for different seats. The right side of the display is optimized for right seat users, and the left side for left seat users. This localized optimization allows the display to be universally accessible from both seats while providing seat-specific manipulability benefits.

AI summary
A display control device for controlling a display screen image of a touch-panel display from both a passenger seat and a driver's seat of a vehicle. The display control device includes a controller for controlling the display screen image based on a touch manipulation performed in regard to the touch-panel display by the user. The controller outputs a first control command for displaying a home screen image including a passenger seat icon and a driver's seat icon, and outputs a second control command for displaying a settings screen image pertaining to the passenger seat and the driver's seat. The driver's seat icon includes a set temperature for the driver's seat. The passenger seat icon includes a set temperature for the passenger seat. The passenger seat settings screen image and the driver's seat settings screen image being arranged on the display screen image so as to have bilateral symmetry.
