Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick-change vice bases experience elastic fatigue and deformation of rubber rings during repeated use, leading to inefficient and time-consuming fixture replacements.
Innovation Solution
A vice quick-change base with a lead screw and movable block system that eliminates the need for rubber rings by using a first and second holding groove structure, a lead screw, and a movable block set to push the quick-change couplers in and out of positioning holes, allowing for quick and efficient replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rubber rings are used to push the quick coupler out of the positioning hole, then quick replacement is enabled, but elastic fatigue and deformation occur during repeated use
Solution Approach 1:
The patent removes the rubber ring component from the system entirely. Instead of using elastic deformation of a rubber ring to push the coupler out, the invention uses a lead screw mechanism with movable blocks that can be actuated to push the coupler out through a pushing block, thereby eliminating the reliability issue of rubber ring fatigue while maintaining the quick replacement function
Solution Approach 2:
The patent replaces the elastic mechanical system (rubber ring) with a threaded mechanical system (lead screw). The lead screw converts rotational motion into linear motion of the movable blocks, which then push the coupler out through the pushing block. This substitution eliminates the need for elastic materials and their associated fatigue problems
2Productivity
If repeated pressing operations are performed on the quick coupler, then the coupler can be removed, but elastic fatigue and deformation of the rubber ring occur
Solution Approach 1:
The patent extracts and removes the rubber ring from the system, replacing it with a lead screw mechanism. The movable blocks actuated by the lead screw push the coupler out through the pushing block, enabling repeated operations without the elastic fatigue that limits rubber ring service life
Solution Approach 2:
The patent changes the operational mechanism from elastic deformation (rubber ring) to threaded mechanical motion (lead screw). The lead screw mechanism can be repeatedly actuated without fatigue by converting rotational input into precise linear displacement of the movable blocks, which then push the coupler out through the pushing block
