Rice Transplanter Stop Button Layout for Tactile Identification
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.
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 interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation portions are provided in the operation device, then the functionality of the operation device is enhanced, but the ease of operation deteriorates because users cannot easily identify the correct button functions
Solution Approach 1:
The patent applies local quality by providing tactile differentiation at specific locations on the operation device. Different regions of the operation portions have distinct tactile characteristics (smooth vs. rough surfaces), allowing users to identify button functions through touch alone. This localized tactile variation enables intuitive operation without visual confirmation, resolving the contradiction between enhanced functionality and ease of operation.
2Reliability
If users must visually confirm button functions to avoid pressing wrong operation portions, then operational accuracy is improved, but the productivity deteriorates due to increased operation time
Solution Approach 1:
The operation device provides self-service through tactile feedback that automatically guides users to the correct buttons. The differentiated tactile surfaces enable users to identify and operate the correct buttons through touch alone, without requiring visual confirmation. This self-guiding mechanism maintains operational accuracy while eliminating the time loss associated with visual checking, thus resolving the contradiction between reliability and productivity.
3Device complexity
If operation portions are provided on a flat front surface, then the device complexity is reduced, but the ease of operation worsens due to lack of tactile differentiation
Solution Approach 1:
The patent maintains overall structural simplicity while introducing localized tactile variations on the operation portions. The operation portions themselves remain simple elements on the front surface, but they incorporate localized tactile differences (smooth vs. rough surfaces) that provide intuitive identification. This approach resolves the contradiction by keeping the device structurally simple while enhancing ease of operation through local tactile quality differentiation.

AI summary
An operation device includes a stop button that is provided on a front surface of a main body of the operation device and receives, from a user, an instruction to cause a rice transplanter to perform a stop action of autonomous travel and includes partial protruding portions that are provided near the stop button on the front surface of the main body and protrude forward from the front surface of the main body.
