Vertical Opening Work Wear Pocket with Dual Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pockets in work wear designed to hold protective pads often cause discomfort due to heat generation and pad displacement, especially when the opening is upwards or downwards, leading to issues with rainwater accumulation and pad positioning.
Innovation Solution
A pocket with a vertical opening and a double closing feature, where the outer closing feature can be opened for ventilation or closed for heat retention, using materials like Cordura®, Kevlar®, or Dyneema® for durability and elasticity, with an integrated inner flap for secure pad positioning and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pocket opening is provided upwards or downwards, then it is easy to insert and withdraw the protective pad, but the protective pad has a tendency to be displaced and rainwater or gravel will accumulate in the pocket
Solution Approach 1:
The pocket opening is positioned on the side of the pocket rather than at the top or bottom, creating an asymmetric configuration that prevents rainwater accumulation while maintaining pad accessibility. The vertical orientation of the opening in use allows the pad to be easily inserted and withdrawn without displacement.
2Reliability
If the outer closing feature is made from extremely durable material, then the pocket provides reliable protection, but the material is thicker, heavier and more cumbersome causing elevated heating and sweating
Solution Approach 1:
The closing feature is divided into two separate features: an outer closing feature made from durable material for security, and an inner closing feature made from lighter material for comfort and ventilation. This segmentation allows each feature to optimize its specific function without the drawbacks of a single heavy material.
Solution Approach 2:
Different materials are used for different parts of the closing system. The outer closing feature uses extremely durable material where strength is critical, while the inner closing feature uses lighter material closer to the skin to reduce heat generation and improve comfort.
3Temperature
If the pocket is completely enclosed to retain heat, then warmth is maintained in cold climates, but ventilation is blocked and the pad cannot be secured
Solution Approach 1:
The closing features are designed to be adjustable rather than fixed. The outer and inner closing features can be independently opened or closed, allowing dynamic adaptation to different environmental conditions and operational needs, providing both ventilation and heat retention when required.

AI summary
Pocket (11, 12, 17), particular a pocket for use in a work wear garment (10, 15), where said pocket has an inner layer (10') and an outer layer (19), where said inner layer and said outer layer are connected on a substantial part of the pocket's outline, and where in use the pocket's opening (13, 18) is on a vertical side of the garment, and where the pocket has a double closing feature - an inner and an outer closing feature (32, 30), where the outer closing feature completely closes the pocket, and where the inner closing feature has ventilation openings (33).
