Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation devices require users to manually switch between multiple controls, leading to decreased operability and aesthetic appeal, and touch panels can be difficult to use due to finger smudges and complex interfaces.
Innovation Solution
A movable operation unit with capacitive touch sensors and tactile detectors that allows for intuitive button selection and operation via touch and movement, eliminating the need for multiple switches and improving user interface clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple switches are arranged to provide multiple input functionalities, then the functionality is improved, but the operability deteriorates because the user must move hand from one switch to another
Solution Approach 1:
Multiple switches are merged into a single operation unit that can detect both touching and movement. The operation unit integrates multiple input functionalities (touching for selection, movement for scrolling/selecting) into one component, eliminating the need for users to physically move between separate switches while maintaining diverse input capabilities
2Adaptability or versatility
If more switches are added to increase functionalities, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The operation unit is designed as a universal component that performs multiple functions: detecting touching for button selection, detecting movement for scrolling and selecting operations, and integrating these functions into a single device. This multi-functional design reduces the quantity of components needed while maintaining diverse functionalities
3Manufacturing precision
If margins are provided between switches in an arranged structure, then the manufacturing precision is improved, but the aesthetic appeal deteriorates
Solution Approach 1:
Multiple switches are merged into a single integrated operation unit with a continuous surface. This eliminates the need for margins between separate switches, allowing for a more aesthetically pleasing continuous design while maintaining precise manufacturing through the unified structure of the operation unit
4Device complexity
If a touch panel is used as operation device, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in touching and visible smears
Solution Approach 1:
The touch panel functionality is segmented into two distinct detection modes: touching detection for button selection and movement detection for scrolling/selecting operations. This segmentation provides clear tactile feedback and distinct operational modes, making the interface easier to use while maintaining the simplicity of a single panel structure

AI summary
An operation device includes an operation unit configured to be movable relative to a device body of the operation device. The operation device includes a first detector that detects touching of the operation unit and a second detector that detects movement of the operation unit relative to the device body. The operation device further includes a controller that processes detection signals of the first detector and the second detector so that the movement of the operation unit relative to the device body and the touching of the operation unit correspond to inputs for operating an operation subject apparatus.
