Pivoting Wire Stripping Jaw for Multitool Insulation Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knives lack the capability to efficiently strip insulation from wires, which is necessary for electrical conductivity in various professional and household applications, requiring a more specialized tool for precise incision without damaging the inner wire.
Innovation Solution
A multitool with pivotally connected jaw members and a wire stripping tool member, featuring wire engaging surfaces and a locking mechanism, allows for the removal of insulation from wires of different diameters by adjusting to specific angles and orientations, enabling precise cutting within a handle configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional knife is used to strip wire insulation, then the incising capability is available, but the precision and control to avoid damaging the inner wire is insufficient
Solution Approach 1:
The wire stripping function is segmented from the general cutting function by providing a specialized wire stripping tool member with jaw members specifically designed for wire handling. The jaw members include features like wire engaging surfaces, slots for different wire diameters, and a stop member to control opening angle, separating the precision wire stripping task from general-purpose cutting.
Solution Approach 2:
The wire stripping tool member acts as an intermediary device between the user and the wire. It includes a lock bar mechanism that mediates the force application, and jaw members that intermediate the contact between the cutting edge and the wire, providing controlled engagement and preventing excessive force that could damage the inner conductor.
2Measurement precision
If a specialized wire stripping tool is used, then the precision insulation removal is achieved, but the versatility of the pocket knife is reduced
Solution Approach 1:
The wire stripping tool member is merged with the pocket knife by attaching it to the handle. The tool member can be positioned within the handle's channel region and includes features like a lock bar that integrates with the knife's locking mechanism. This combining allows the knife to maintain its general cutting versatility while adding specialized wire stripping capability.
Solution Approach 2:
The wire stripping tool member is designed with universal features to handle various wire types and diameters. The jaw members include slots of different sizes to accommodate different wire diameters, and the stop member allows adjustment of the opening angle to suit different stripping requirements, making the tool versatile for multiple wire stripping scenarios.
3Ease of operation
If the wire stripping tool member is always extended, then the wire stripping capability is readily available, but the compactness and portability of the pocket knife is compromised
Solution Approach 1:
The wire stripping tool member is designed to nest within the handle's channel region when not in use. The jaw members can be positioned within the handle, and the lock bar mechanism allows the tool member to be secured in a retracted position, creating a compact form factor that maintains portability while allowing easy deployment when needed.
Solution Approach 2:
The wire stripping tool member is designed with dynamic positioning capability, allowing it to transition between retracted and extended positions. The lock bar mechanism provides dynamic locking at different positions, enabling the tool to be compact during storage yet readily accessible during operation, balancing portability with ease of operation.

AI summary
A tool member for a multitool which is configured to strip wire. The tool member has first and second members which in one form are pivotally attached at a common axis on the handle portion of a multitool where the tool member has an extended orientation and can be retracted into the channel region of the tool member.
