Tool Holder With Removable Handle For Tap Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tap wrench designs are cumbersome for removing the handle during thread cutting operations, as sliding it back and forth requires significant effort, and the handle can easily fall out, making it inconvenient to remove the tap from the work piece.
Innovation Solution
A tool holder with a slideable T-handle configuration and a release mechanism that allows the handle to be separated from the body, featuring stop positions to prevent accidental removal during use and a spring-loaded stop member with set screws to facilitate easy extraction, enabling the handle to be used for spinning the tap out after threading is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is made easily removable to facilitate tap removal, then the ease of operation improves, but the risk of accidental loss increases
Solution Approach 1:
The handle retention system transitions from a static fixed state to a dynamic controllable state. During normal operation, the handle is retained by friction and stop positions. When removal is needed, the user actuates the release mechanism (pushing the top surface) which shifts the stop member, allowing the handle to be pulled out. This dynamic transition resolves the contradiction between easy removal and accidental loss.
Solution Approach 2:
The release mechanism acts as an intermediary between the user's intent to remove the handle and the actual separation. The pushable top surface and internal stop member create a controlled interface that prevents accidental removal while enabling intentional removal. This intermediary mechanism resolves the contradiction by adding a control layer.
2Reliability
If the handle is made fixed and secure, then the reliability improves, but the ease of operation for removing the tap deteriorates
Solution Approach 1:
The system transitions from a permanently fixed state to a dynamically controllable state. The handle is securely retained during normal operation through friction and stop positions, but can be easily removed when needed by actuating the release mechanism. This dynamic capability resolves the contradiction between secure retention and easy removal.
Solution Approach 2:
The release mechanism is designed to be self-actuating through a simple push motion on the top surface. The user's pushing action directly shifts the stop member and enables handle removal without requiring additional tools or complex operations. This self-service approach resolves the contradiction by making removal as easy as pushing.
3Adaptability or versatility
If the handle is made slideable for tight spaces, then the adaptability improves, but the effort required for operation increases
Solution Approach 1:
The handle is segmented into a removable portion and a body portion. The removable handle can be easily detached and reattached, allowing the user to adjust the handle configuration for different working conditions including tight spaces. This segmentation resolves the contradiction by providing adaptability without requiring continuous sliding operations.
Solution Approach 2:
The handle system transitions from a continuously slideable mechanism to a dynamically removable and reconfigurable system. The handle can be easily removed and repositioned, providing adaptability for tight spaces without the cumulative effort of repeated sliding operations. This dynamic reconfigurability resolves the contradiction between adaptability and operational effort.

AI summary
A tool holder comprises an elongated body having a first end portion for receiving a handle and a second end portion with an adjustable tool retaining mechanism for holding a tool, an elongated handle releasably retained in the first end portion and being configured to be slideable between stop positions at opposite ends, and a release mechanism at the first end portion configured to enable the handle to be separated from the body when operated.
