Two-Sleeve Protective Garment With Fixed Inner Protection
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
3Reliability
If double layer construction is used for cold weather, then adequate protection is provided, but arm movements are limited
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.
