Wire Stripper With Nested Casings for Narrow Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire strippers are restricted by environmental space due to their wide design, making it difficult to strip wires in narrow spaces while protecting the integrity of the leads.
Innovation Solution
A wire stripper design comprising a first main body with a rear grip and lower engaging portion, a second main body with an outer and inner casing and rails, and a third main body with a spring mechanism, allowing for smooth stripping and protection of leads, and enabling operation in narrow spaces through a sliding and pivoting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wire stripper uses a conventional wide clipping body design, then it provides sufficient space for operation, but it cannot be used in narrow spaces
Solution Approach 1:
The wire stripper is divided into three separate main bodies (first main body with lower engaging portion, second main body with outer and inner casings, third main body with acting portion), allowing the components to be distributed in narrow spaces while maintaining functional integrity
Solution Approach 2:
The second main body includes an inner casing received within an outer casing, creating a nested structure that reduces the overall spatial footprint while maintaining the necessary functional components within each casing
2Productivity
If the wire stripper applies sufficient force to strip insulation, then stripping efficiency is improved, but the leads may suffer damage
Solution Approach 1:
The stripping force is concentrated locally at the cutting edges of the engaging portions where insulation removal is needed, while the spring portion provides distributed elastic force that prevents excessive localized stress on the leads
Solution Approach 2:
The spring portion is pre-configured to provide elastic cushioning force that automatically adjusts during operation, cushioning against excessive force that could damage leads while maintaining sufficient stripping force
3Stability of the object's composition
If the engaging portions remain engaged after stripping, then structural integrity is maintained, but the naked leads may suffer damage
Solution Approach 1:
The engaging portions are designed to dynamically transition from an engaged state during stripping to a separated state after stripping, with the spring portion providing the mechanical advantage for easy separation while maintaining structural integrity during the engaged phase
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient stripping of wire insulation without damaging the leads and allows operation in confined spaces due to the elastic force and rail system, ensuring proper force application and easy disengagement to prevent lead damage.
Implementation Method 1
The elastic force of the spring portion allows the upper engaging portion to be separated from the lower engaging portion after their engagement

AI summary
A wire stripper includes: a first main body having a main body portion, a rear grip, a lower engaging portion and an internal accommodating space; a second main body having an outer casing, an inner casing received in the outer casing, two upper engaging portions, two first rail holes located on both sides of the outer casing, two second rails, two first rails located on both sides of the inner casing and two second rail holes; and a third main body having a left casing and a right casing combined with each other, a front grip extending downwards from the left casing and the right casing, an acting portion connected between the second main body and the third main body, and a spring portion abutting in the front grip and the rear grip. The second main body and the third main body are received in the accommodating space.
