Extraction Tool With Sliding Non-Contact Part For Broken Phone Plug Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools, such as pinching tools, struggle to efficiently extract broken phone plugs from audio jacks without adhering to the inner surfaces, which can complicate the extraction process and require disassembly of seat monitors.
Innovation Solution
An extraction tool comprising a grip, a first member with a non-contact part and a contact layer, and a second member that surrounds the first member, allowing the non-contact part to slide. The contact layer, with an adhesive layer, is used to extract the broken phone plug while preventing adherence to the inner surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive material is used to extract objects, then extraction capability is improved, but adhesion to inner surfaces of holes occurs causing complications
Solution Approach 1:
The first member is designed with differentiated zones: a non-contact part (body portion) that slides without adhering to hole surfaces, and a contact layer (adhesive layer) at the tip that selectively adheres only to the target object. This local differentiation of adhesive properties enables extraction while preventing unwanted adhesion to the hole's inner surface.
Solution Approach 2:
The first member is segmented into distinct functional portions: a non-contact part for sliding and a contact layer for adhesion. This segmentation allows the tool to perform multiple functions - sliding through the hole without sticking and adhering to the object for extraction - thereby resolving the contradiction between extraction capability and preventing unwanted adhesion.
2Ease of operation
If conventional pinching tools are used, then adhesion and peeling can be performed, but disassembly of seat monitors is required complicating the process
Solution Approach 1:
The extraction tool integrates multiple functions into a single device: the first member can slide within the second member for positioning, the contact layer provides adhesion capability, and the overall structure enables direct extraction without disassembly. This multi-functionality eliminates the need for separate disassembly steps required by conventional pinching tools.
3Productivity
If adhesive material projects outside the opening, then extraction capability is improved, but adhesion to surrounding surfaces occurs
Solution Approach 1:
The harmful adhesion function is extracted and isolated to only the necessary contact layer at the tip of the first member, while the non-contact part is designed to slide without adhesion. This selective extraction of adhesive function ensures that adhesion occurs only where needed (on the target object) and not on surrounding surfaces.

Function Achieved in This Case
The extraction tool effectively removes broken phone plugs from audio jacks without adhering to the inner surfaces, simplifying the extraction process and eliminating the need for disassembling seat monitors.
Implementation Method 1
a contact layer provided at the end of the non-contact part and being able to come into contact with the object
Implementation Method 2
The non-contact part of the first member is slidable with respect to the second member

AI summary
An extraction tool that is configured to extract an object inside a hole includes: a grip having an end; a first member including a non-contact part provided at the end of the grip and not being able to come into contact with the object, and a contact layer provided at the end of the non-contact part and being able to come into contact with the object; and a second member surrounding at least a part of the first member. The non-contact part of the first member can slide with respect to the second member.
