Tactile Stop Button Layout for Rice Transplanter Operation Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operation devices for work vehicles with multiple operation portions are difficult to use due to the challenge of identifying the correct function assigned to each button, leading to decreased operability as users must visually check the device to avoid errors.
Innovation Solution
An operation device with a first operation portion on its front surface and a protruding portion near it, allowing for intuitive operation and improved user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation portions are provided in the operation device, then the functionality is enhanced, but the ease of operation deteriorates due to difficulty in identifying correct functions
Solution Approach 1:
The patent applies local quality by providing tactile differentiation at specific locations on the operation device. The first operation portion has a first tactile characteristic while the second operation portion has a second tactile characteristic different from the first. This allows each operation portion to have unique local properties that enable intuitive identification without visual confirmation, resolving the contradiction between providing multiple functions and maintaining ease of operation.
2Adaptability or versatility
If multiple operation portions are provided in the operation device, then the functionality is enhanced, but the time required for correct operation increases due to need for visual confirmation
Solution Approach 1:
The patent eliminates the need for visual confirmation by providing distinct tactile characteristics at different operation portions. Users can identify and operate the correct button through touch alone, significantly reducing the time required for operation while maintaining multiple functional capabilities.
3Adaptability or versatility
If multiple operation portions are provided in the operation device, then the functionality is enhanced, but the reliability deteriorates due to increased risk of pressing wrong operation portion
Solution Approach 1:
The patent enhances reliability by providing tactile differentiation between operation portions. The distinct tactile characteristics prevent accidental or erroneous pressing by allowing users to confidently identify the correct operation portion through touch, thereby reducing the risk of wrong operations while maintaining multiple functions.
