Solution Overview

Problem

Conventional protective garments, such as those used in motorcycling and skiing, face difficulties in adjusting ventilation due to the complexity of zip fasteners, especially when wearing gloves, leading to increased risk of accidents and inadequate breathability.

Innovation Solution

A protective garment with a deformable element that transitions between a closed and open configuration to control airflow through a ventilation opening, allowing for simpler operation even with gloves on, using a spring steel element integrated into a flap for easy movement between configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a zip fastener is used to control ventilation, then the ventilation can be adjusted, but the operation becomes difficult and complicated when wearing gloves

Engineering Contradiction:
Improveventilation control operationVSAvoidsafety during operation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the complex zip fastening mechanism and replaces it with a simple deformable element that can be easily manipulated. The deformable element is inserted through a hole in the garment and deformed to open or close the ventilation opening, eliminating the need for gloves to manipulate a zip mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical zip fastener system with a simpler deformable element system. Instead of using a zip that requires pulling and threading motions, the deformable element is simply deformed (e.g., pinched or bent) to achieve the same ventilation control function, making it accessible even when wearing gloves.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a conventional zip fastener is used, then ventilation adjustment is possible, but the garment complexity increases

Engineering Contradiction:
Improveventilation adjustment capabilityVSAvoidgarment structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent removes the complex zip fastener mechanism from the garment structure and replaces it with a minimal deformable element. This extraction of the essential function (ventilation control) while eliminating unnecessary complexity results in a simpler garment design that achieves the same adaptability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If waterproof zip fasteners are used to guarantee impermeability, then the garment becomes more expensive

Engineering Contradiction:
Improveimpermeability guaranteeVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent uses a simple deformable element instead of expensive waterproof zip fasteners. The deformable element is a minimal, low-cost component that achieves the necessary impermeability when closed, eliminating the need for costly waterproofing mechanisms while maintaining the reliability of the garment's protective function.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
