Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping devices for removing parts like roller bearings and sleeves from a housing are cumbersome due to their complexity and inability to adapt to different sizes, often requiring manual adjustments and multiple parts.
Innovation Solution
A semi-automatic gripping device with a spring-loaded mechanism that automatically adjusts to various inner ring diameters by moving the inner and outer bodies along a symmetry axis, featuring a central thorn, inner and outer bodies, and movable arms with slots and claws, allowing for easy assembly and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spring-loaded mechanism is used to automatically adjust gripping positions, then adaptability to different sizes is improved, but device complexity increases
Solution Approach 1:
The gripping device is designed with a spring-loaded mechanism that enables a single device to adapt to multiple sizes of inner rings automatically. The spring allows the jaws to adjust their gripping position based on the diameter of the inner ring, making the device universal for different bearing sizes without requiring multiple specialized tools.
Solution Approach 2:
The gripping device incorporates a dynamic spring mechanism that automatically adjusts the gripping position based on the size of the inner ring. The spring allows the jaws to move and adapt their position dynamically, transforming a static gripping device into a dynamic one that can handle various dimensions.
2Ease of operation
If manual adjustments are required for different sizes, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The spring-loaded mechanism enables the gripping device to self-adjust to different inner ring diameters without requiring manual intervention. The spring automatically positions the jaws according to the size of the inner ring, making the device self-servicing and eliminating the need for operator adjustments.
Solution Approach 2:
The spring is pre-loaded to provide the necessary force for automatic adjustment. This preliminary action of the spring ensures that when the gripping device is engaged with an inner ring, the jaws automatically move to the correct gripping position without requiring the operator to manually adjust them.
3Adaptability or versatility
If multiple gripping positions are provided for different sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The spring-loaded mechanism enables a single gripping device to provide multiple gripping positions for different inner ring diameters. Instead of requiring separate devices or complex adjustment mechanisms, the spring allows one device to perform multiple functions across a range of sizes.
Solution Approach 2:
The spring mechanism allows the gripping device to change its gripping parameter (position) based on the diameter of the inner ring. By varying the diameter of the inner ring, the spring automatically adjusts the gripping position, enabling the device to adapt to different parameters without complex mechanisms.
