Solution Overview

Problem

Existing wearing devices for tools, such as knives, are prone to pollution and lack flexibility in their brackets, which impairs their functionality.

Innovation Solution

A wearing device with a recording device that includes a holding device with stop and bar agents to securely attach and rotate the recording device relative to a base section, allowing for flexible positioning and easy attachment/detachment without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the receiving device is designed with a closed structure to protect the tool, then protection is improved, but dirt particles accumulate inside and impair function

Engineering Contradiction:
ImproveprotectionVSAvoiddirt particle accumulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The receiving device incorporates openings in its structure that allow dirt particles to escape while maintaining tool protection. These openings enable selective permeability - keeping the tool secure while allowing contaminants to pass through, resolving the contradiction between protection and contamination resistance

Inventive Principle:
Principle #31Porous materials

2Stability of the object's composition

If the receiving device is firmly fixed to the base part, then stability is improved, but flexibility in positioning is reduced

Engineering Contradiction:
Improvefirm fixationVSAvoidpositioning flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The holding device incorporates a rotatable connection between the receiving device and base part, allowing the assembly to transition from a static fixed position to a dynamic adjustable position. This enables the user to rotate the receiving device to different angles while maintaining secure attachment, resolving the contradiction between firm fixation and positioning flexibility

Inventive Principle:
Principle #15Dynamics

3Reliability

If the receiving device is permanently attached to the base part, then connection reliability is improved, but ease of detachment is reduced

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of detachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holding device is designed as a separate, detachable component that connects the receiving device to the base part. This segmentation allows the connection to be reliably formed when assembled, while also enabling easy detachment by simply separating the modular components, resolving the contradiction between connection reliability and ease of detachment

Inventive Principle:
Principle #1Segmentation

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

The solution provides a wearing device that is resistant to pollution, maintains high flexibility in its bracket, and allows for secure and easy attachment of tools, enhancing usability and maintenance.

Implementation Method 1

The clipping takes place, for example, by locking with an elastically deformable latch on one of the parts, which can engage in a recess in the other part

Methodology Applied
Scientific EffectElastic deformation: Elasticity

Implementation Method 2

The bearing areas interact, for example, with a reveal of the opening to form the pivot bearing

Methodology Applied
Scientific EffectPivot bearing: Axle
