Push-Swipe Operation Interface for Expanding Vehicle Control Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation devices for activating onboard apparatuses in vehicles face challenges in flexibly expanding operational functions, leading to increased component count and cost when new functions are added, as switch functions are typically fixed.
Innovation Solution
An operation device with a movable operation unit that can be swiped or pushed in multiple directions, incorporating detection mechanisms to control graphics on a display unit, allowing for flexible expansion of operational functions through touch and swipe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-function switches are used for each apparatus, then the operational function is reliable and simple to operate, but the device complexity and cost increase when new functions are added
Solution Approach 1:
A single operation unit is designed to perform multiple functions by detecting different operation types (push operation in first direction, push operation in second direction, swipe operation). The detection unit identifies the operation type and the control unit activates different apparatuses or functions based on the detected operation, allowing one physical component to replace multiple dedicated switches.
Solution Approach 2:
The operation unit transitions from static fixed-function switches to a dynamic multi-functional interface. The same physical operation unit can be operated in multiple ways (pushing in different directions, swiping), and the system dynamically responds by activating different functions or apparatuses based on the detected operation type, enabling flexible function expansion without adding components.
2Adaptability or versatility
If multiple dedicated switches are arranged for different apparatuses, then each switch has a fixed reliable function, but the ease of operation decreases and space is wasted
Solution Approach 1:
One operation unit replaces multiple dedicated switches, consolidating their functions into a single compact component. The detection unit distinguishes between different operation types (push direction, swipe), enabling the same physical space to control multiple apparatuses and functions, thereby reducing the panel area required while maintaining functional versatility.
3Device complexity
If a single operation unit controls multiple apparatuses, then the device complexity is reduced, but the difficulty of detecting and measuring the operation type increases
Solution Approach 1:
The detection function is segmented into a separate detection unit that specializes in identifying operation types. The detection unit receives signals from the operation unit and determines whether the operation is a push in the first direction, push in the second direction, or swipe operation. This segmentation of detection functionality simplifies the overall system while accurately distinguishing between different operation types.
Solution Approach 2:
The detection unit acts as an intermediary between the operation unit and the control unit. It receives raw input signals from the operation unit, processes and identifies the operation type, and then transmits the interpreted information to the control unit. This intermediary layer simplifies the control unit's task and enables accurate differentiation of multiple operation types without increasing overall system complexity.

AI summary
An operation device includes an operation part that is provided so as to move relative to a device body in each of a first direction and a second direction from a neutral position. Touch operations on the panel surface of the operation part are detected by a sensor provided to the operation part. A touch operation on the operation part is designated as an operation for selecting an icon group on a screen. A push operation on the operation part, in the first direction or the second direction, is designated as an operation for determining a selection state on the screen. A one-finger tracing operation on the operation part is designated as an operation for changing an icon selected on the screen. A two-finger tracing operation on the operation part is designated as an operation for changing the screen.
