Touch Switch Knob Path Control to Prevent Accidental Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch switch interfaces in industrial robots are prone to unintentional ON/OFF switching due to accidental user interactions, leading to erroneous operations and safety concerns.
Innovation Solution
A software switch program that displays a touch switch with a knob and guide on a display section, requiring a specific sequence of touch input operations along distinct paths to switch between states, thereby minimizing accidental changes and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple touch switch interface is used, then ease of operation is improved, but reliability deteriorates due to unintentional switching
Solution Approach 1:
The touch switch interface is segmented into multiple distinct touch areas (first touch area and second touch area) arranged in different directions. This segmentation allows the system to differentiate between intentional switching operations (touching both areas) and accidental touches (touching one area), thereby improving reliability while maintaining ease of operation through simple touch gestures.
2Ease of operation
If a touch panel with touch switches is used, then ease of operation is improved, but harmful factors increase due to erroneous operations
Solution Approach 1:
The system implements preliminary anti-action by requiring a specific sequence of touch inputs (first touch on first touch area, then touch on second touch area) before executing the switching operation. This preliminary requirement prevents erroneous operations caused by accidental single touches while preserving ease of operation through intuitive sequential touching gestures.

AI summary
A non-transitory computer-readable medium storing a software switch program for causing a display section to display a touch switch including a knob that is in a state in which the knob selects, of a first choice and a second choice that are in an exclusive relation, the first choice and a guide showing a moving path of the knob from the first choice to the second choice and including a first moving path extending along a first direction and a second moving path extending along a second direction different from the first direction and, when receiving first touch input operation for sliding one of the knob and the guide with respect to the other along the first moving path and second touch input operation for sliding the one of the knob and the guide along the second moving path, switching the state to a state in which the knob selects the second choice.
