Robot Arm Strip Switch Layout for Multi-Angle Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing robot systems have limitations in operability due to the design of input switches, which restricts efficient operation by operators.
Innovation Solution
A robot system with a strip-shaped switch that allows operation at multiple locations around the outer periphery of the arm, enabling the robot controller to transition the robot into a movable state based on the operator's input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single input switch is provided at the distal end portion of the robot arm, then the robot can be operated, but the operability is limited when the robot posture changes
Solution Approach 1:
The single input switch is segmented into multiple input switches arranged along the longitudinal direction of the arm. This segmentation allows different switches to be accessible depending on the arm's posture, thereby maintaining operability across various configurations while solving the limitation of a single fixed switch location
Solution Approach 2:
The input switches are arranged not only along the longitudinal direction but also extend in the radial direction from the arm's centerline. This two-dimensional arrangement ensures that at least one switch remains accessible from the operator side regardless of the arm's rotational posture, solving the adaptability problem
2Ease of operation
If the input switch is fixed at one location, then the structure is simple, but the operator cannot easily access it when the robot posture changes
Solution Approach 1:
Multiple input switches are provided, each capable of performing the same input function. This multi-functionality ensures that regardless of which switch the operator accesses, the same operational effect is achieved, maintaining simplicity in function while improving accessibility across different postures
