Solution Overview

Problem

Existing motorcycle protective jackets with removable sleeves face issues of reduced protection and comfort when transitioning from sleeved to sleeveless configurations due to the movement of protective elements, particularly affecting shoulder and elbow areas, and the need for double-layer constructions that limit mobility.

Innovation Solution

A two-sleeve protective garment design featuring inner sleeves with integrated protective elements and a connection system that maintains protection and comfort by keeping the inner sleeves in place, even when outer sleeves are removed, using connecting flaps and internal connections to ensure proper positioning and reduce abrasion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If protective elements are applied on removable sleeves, then the garment can adapt to different weather conditions, but the protective elements move from their original position when transitioning to sleeveless configuration

Engineering Contradiction:
Improveweather condition adaptationVSAvoidprotective element positioning
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The protective garment is divided into three main segments: the body garment, removable outer sleeves, and inner sleeves with protective elements. This segmentation allows the protective elements to remain on the body garment while enabling removal of outer sleeves for weather adaptation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner sleeves with protective elements are nested within the body garment structure, while removable outer sleeves can be placed over them. This nested configuration ensures protective elements stay positioned on the body garment regardless of outer sleeve presence.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If inner shell is fastened to outer shell at front portion only, then the garment allows ease of operation, but the inner shell moves with respect to outer shell at shoulder portions

Engineering Contradiction:
Improvegarment donning and doffingVSAvoidrelative position between shells
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

Different fastening qualities are applied to different regions: the front portion uses simple fastening for ease of operation, while shoulder portions use reinforced fastening elements to maintain stable relative positioning between inner and outer shells.

Inventive Principle:
Principle #3Local quality

3Reliability

If double layer construction is used for cold weather, then adequate protection is provided, but arm movements are limited

Engineering Contradiction:
Improveprotection adequacyVSAvoidarm movement freedom
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The garment transitions from a static double-layer construction to a dynamic system where outer sleeves can be removed. This allows the garment to adapt between cold weather protection mode (double layer) and warm weather ventilation mode (single layer), maintaining protection adequacy while enabling arm movement freedom when needed.

Inventive Principle:
Principle #15Dynamics
