Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional crimping tools have exposed guiding grooves that are prone to damage and dirt accumulation due to the static nature of these components, which affects their functionality and longevity.

Innovation Solution

The guiding grooves are integrated into the slide module, and a fixed shaft is positioned across the base's side walls, ensuring the grooves remain covered and protected from damage and dirt, with the slide module guided by this shaft to maintain functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the guiding grooves are made as static components on the seat, then the structure is simple, but the guiding grooves are exposed and easily damaged and get dirt

Engineering Contradiction:

Improvestructure simplicityVSAvoidguiding groove durability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent inverts the conventional design by making the guiding grooves movable (attached to the slider) rather than static (on the seat), and making the shaft fixed rather than movable. This inversion protects the guiding grooves from exposure and damage while maintaining structural simplicity.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The guiding grooves are nested on the slider body rather than being separate components on the seat. This integration protects the guiding grooves within the slider structure, preventing them from being exposed to external damage and dirt accumulation.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the shaft is made as a rotating piece with guiding grooves on the seat, then the mechanism is conventional, but the guiding grooves are exposed to damage and dirt

Engineering Contradiction:

Improvemechanism conventionalityVSAvoiddirt and damage exposure

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional arrangement by fixing the shaft to the seat and making the guiding grooves movable on the slider. This reversal protects the guiding grooves from exposure to harmful factors like dirt and damage while maintaining the crimping mechanism's functionality.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The guiding grooves are integrated into the slider body as a protective structure, effectively creating a shielded path for the shaft that prevents dirt and damage from affecting the guiding surfaces.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of manufacture

If the guiding grooves are exposed, then the structure is open and simple, but they accumulate dirt and get damaged

Engineering Contradiction:

Improvestructural opennessVSAvoidguiding groove cleanliness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The guiding grooves are nested within the slider structure rather than being exposed on the seat. This integration provides natural protection against dirt accumulation while maintaining ease of manufacture through the unified slider design.

Inventive Principle:

Principle #7Nested doll (Nesting)

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

This design prevents damage and dirt accumulation in the guiding grooves, enhancing the tool's durability and operational reliability by dispersing the driving and guiding forces across multiple points, reducing stress concentration and improving the crimping process.

AI summary

A crimping tool includes a base, a press handle, a slide module, a link and a fixed fix shaft. The base has two first side walls and to sliding space is defined therebetween. One end of the press handle is pivoted at an end of the base. The slide module is slidably accommodated in the sliding space and has a guiding groove. Two ends of the link are pivoted at the press handle and the slide module separately. The fix shaft is disposed across the two first side walls and inserted in the guiding groove. When the press handle drives the slide module sliding in the sliding space through the link, the guiding groove of the slide module will be guided and restricted by the fix shaft. Therefore, the guiding grooves will not be damaged and get dirt.
