Modular Gripper Fusible Part Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing modular grip systems for bodywork elements in vehicle manufacturing, while effective, face significant downtime due to the need to adjust tool holders after a fuse zone breaks, which combines shock protection and positioning functions, leading to prolonged troubleshooting times.
Innovation Solution
The modular grip system relocates the protection function to a separate, non-adjustable fuse part, allowing the tool holder to break without affecting the adjustment of the tool holder's position, thus reducing repair times by dissociating the fuse function from the adjustment function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fusible zone is integrated into the tool holder support part, then the protection function is provided, but the adjustment function is affected requiring time-consuming readjustment after breakage
Solution Approach 1:
The patent divides the tool holder support part into two separate components: a fusible part containing the fusible zone for protection, and a tool holder support part for positioning and adjustment. This segmentation allows the fusible part to break and be replaced without affecting the adjustment settings of the tool holder support part, thereby reducing troubleshooting time while maintaining protection functionality.
Solution Approach 2:
The fusible zone function is extracted from the tool holder support part and placed into a separate fusible part. This extraction allows the protection function to be isolated from the adjustment function, so that when the fusible part breaks, the tool holder support part retains its positioning settings and does not require readjustment.
2Object-affected harmful factors
If the tool holder support part contains both fusible zone and adjustment functions, then protection is provided, but replacement requires complex readjustment procedures
Solution Approach 1:
The patent segments the support structure into a fusible part with the fusible zone and a tool holder support part with adjustment mechanisms. This segmentation ensures that impact protection is provided by the fusible part while replacement simplicity is achieved by isolating it from the adjustment functions located in the separate tool holder support part.
Solution Approach 2:
The fusible zone is extracted from the tool holder support part and placed in a dedicated fusible part. This extraction simplifies repair by allowing the fusible part to be replaced independently without disturbing the adjustment settings of the tool holder support part, thereby reducing replacement complexity.
3Object-affected harmful factors
If the fusible zone is placed in the tool holder support part, then shock protection is achieved, but production stoppage time increases
Solution Approach 1:
The patent segments the support structure into a fusible part containing the fusible zone for shock protection, and a tool holder support part for positioning. This segmentation enables quick replacement of the fusible part without affecting production timelines, as the tool holder support part retains its settings and does not require readjustment.
Solution Approach 2:
The fusible zone function is extracted into a separate fusible part, allowing shock protection to be maintained while significantly reducing production stoppage time. The fusible part can be quickly replaced without disrupting the adjustment settings of the tool holder support part, thereby minimizing impact on productivity.
