Waist Pocket Retainer Structure for Secure Item Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garments with waist pockets often experience contents falling out during exercise or activities due to inadequate retention mechanisms.
Innovation Solution
Incorporation of an internal pocket retainer within the waist pocket that forms a retention space with elastic edges or a continuous 360-degree structure to securely hold items, using stitching, welding, or adhesives to affix to the waistband or pocket panel, ensuring articles are retained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple waist pocket is used, then the garment structure remains simple, but items fall out during exercise or activities
Solution Approach 1:
The patent implements a nested structure where an inner pocket retainer is placed inside the outer waist pocket. The retainer forms a retention space within the pocket, creating a nested configuration that prevents items from falling out while maintaining the overall pocket structure. This resolves the contradiction by adding a nested retention mechanism rather than redesigning the entire pocket system.
Solution Approach 2:
The patent divides the pocket system into two functional segments: the outer waist pocket structure and the inner pocket retainer. The retainer is further segmented with elastic edges that can independently grip items. This segmentation allows each component to perform its specific function - the outer pocket provides structure while the inner retainer provides retention, resolving the contradiction between simplicity and reliability.
2Reliability
If elastic edges are added to the pocket retainer, then gripping of smaller items is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies elastic material to specific edges of the pocket retainer rather than the entire retainer. This selective parameter change (adding elasticity only where needed for gripping) improves retention of smaller items while minimizing manufacturing complexity. The elastic edges can be attached using standard elastic band techniques integrated into the sewing process.
Solution Approach 2:
The patent applies different properties to different parts of the pocket retainer - the main body remains as simple fabric while only the edges are made elastic. This local quality approach provides enhanced gripping exactly where items contact the retainer perimeter, without requiring the entire retainer to be complex elastic material, thus balancing reliability improvement with ease of manufacture.
3Reliability
If a continuous 360-degree retention space is created, then item retention around the waist is enhanced, but the device complexity increases
Solution Approach 1:
The patent designs the pocket retainer to serve multiple functions simultaneously: it creates a retention space, provides elastic gripping at the edges, and can be configured to extend continuously around the waist. This multi-functionality allows a single component to achieve continuous 360-degree retention coverage without requiring multiple separate retention mechanisms, thus enhancing reliability while controlling complexity.
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
Enhances the retention of items within waist pockets by preventing them from rising or falling out, particularly for smaller items like phones and keys, through resilient gripping and continuous coverage around the waist.
Implementation Method 1
The pocket retainer may be sized or may be at least partially elastic to grip and engage the received articles

AI summary
A garment may include a waistband, a lower extension extending downward from the waistband, an upward facing waist pocket along an exterior of the waistband, the upward facing waist pocket having an interior and a bottom and a pocket retainer within the upward facing waist pocket and forming an internal retention space having a retention space mouth.
