Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots optimized for specific tasks become less versatile and struggle to perform various types of work beyond their initial designation.
Innovation Solution
A gripping device with a first member and a second member, where the first member has higher rigidity than the second member, allowing for versatile gripping and operation across different tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot structure is optimized for specific work, then the work efficiency for that specific task is improved, but the versatility to perform various types of work deteriorates
Solution Approach 1:
The gripping device is designed with a first member having higher rigidity and a second member having lower rigidity, creating a universal gripping mechanism that can adapt to various object types and work tasks. This differential rigidity structure allows the same device to perform both gripping operations and other work functions, eliminating the need for task-specific robot designs
2Reliability
If the robot is designed with specialized structure for specific task, then the task performance is improved, but the ability to automate other work deteriorates
Solution Approach 1:
The gripping device applies local quality by assigning different rigidity characteristics to different members: the first member has higher rigidity for stable gripping, while the second member has lower rigidity for adaptive contact. This localized property differentiation enables reliable task performance across diverse work types without requiring specialized robot designs for each task
