Vehicle Operation Panel Display Reversal for Rotated Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Occupants experience discomfort when operating an operation panel in vehicles with rotated seats, as operation elements become reversed when viewed from a rearward-facing position, especially in autonomous driving modes where seats can face each other.
Innovation Solution
An operation system with a processor that acquires signals indicating seat orientation and rearranges operation elements on the display screen in the longitudinal direction of the vehicle, reversing their arrangement when the seat faces rearward to maintain optimal accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is rotated to face rearward for autonomous driving, then face-to-face seating configuration is achieved, but the arrangement of operation elements becomes reversed causing occupant discomfort
Solution Approach 1:
The operation element arrangement is made dynamic by automatically reversing the display order based on detected seat orientation. The system transitions from a fixed arrangement to a flexible one that adapts to forward-facing or rearward-facing seat positions, resolving the contradiction between configuration flexibility and operational ease
Solution Approach 2:
The system changes the display parameter of operation elements (their arrangement order) based on the seat orientation parameter. When the seat rotates from forward-facing to rearward-facing, the system reverses the sequence of operation elements displayed, maintaining intuitive usability across different configurations
2Device complexity
If operation elements are arranged in fixed positions on the display, then the display layout is simple, but the elements become inaccessible or reversed when seat direction changes
Solution Approach 1:
The display layout transitions from a static fixed arrangement to a dynamic one that automatically reconfigures based on seat orientation. The system detects seat direction and reverses the operation element arrangement accordingly, maintaining simplicity in implementation while achieving adaptability in display configuration

AI summary
An operation system for a vehicle includes a memory, and a processor coupled to the memory and configured to acquire a first signal indicating whether a seat in the vehicle is facing forward or rearward, and generate a display screen by arranging at least two operation elements in a longitudinal direction of the vehicle. The display screen is displayed on an operation panel installed in the vehicle. The processor reverses the arrangement of the at least two operation elements in the longitudinal direction of the vehicle in accordance with the first signal.
