Integrated Tongue Break-off Tool for Coil Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for breaking off and collecting tongues from coil inserts in tap holes are inefficient due to the need for tool replacement, interrupting the workflow and reducing efficiency.
Innovation Solution
A tongue break-off tool with a hook member that hooks onto the tongue, a moving member to diagonally break off the tongue, and a holding member to collect it, eliminating the need for separate tools and improving workflow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate tools are used for breaking off and collecting tongues, then the break-off and collection functions can be performed, but the workflow is interrupted by tool replacement and work efficiency is reduced
Solution Approach 1:
The patent combines the break-off tool and collection tool into a single integrated tool. The break-off portion includes a hook member that hooks onto the tongue, while the collection portion includes a holding member with magnetic attraction force that collects the broken-off tongue. This merging eliminates the need for tool replacement and continuously improves workflow efficiency.
Solution Approach 2:
The integrated tool performs multiple functions: it can both break off the tongue from the insert and collect the broken-off tongue in its holding member. This multi-functionality allows a single tool to complete both operations that previously required separate tools, eliminating workflow interruptions.
2Manufacturing precision
If a hook member is moved in a diagonal direction to break off the tongue, then the tongue can be effectively broken off from the insert, but the moving member must be precisely controlled to achieve the correct breaking position
Solution Approach 1:
Instead of moving the hook member only in the vertical direction (one dimension), the patent moves it in a diagonal direction that combines vertical and horizontal components (two dimensions). This diagonal movement allows the hook to approach the tongue from an optimal angle, ensuring precise break-off at the intended position while maintaining ease of operation.
Solution Approach 2:
The hook member is positioned and oriented in advance before making contact with the tongue. The diagonal approach allows preliminary alignment with the tongue's position and orientation, ensuring that when the breaking action occurs, the hook is already in the correct position and angle for precise break-off.
