Harness Leg Loop Constricting Tube Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for closing or constricting waistbands, leg loops, and footwear openings often fail, slide, or loosen under load, and may add weight, bulk, or complexity, limiting movement and flexibility.
Innovation Solution
A circumference closing system utilizing constrict-able tubular lengths and adjustable lines to releasably retain a selected size of the closable circumference, eliminating the need for belts, clasps, or other hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional closing mechanisms (belts, hooks, clips, laces) are used to constrict waistbands and leg loops, then the garment can be adjusted to fit different sizes, but the mechanisms may fail, slide, or loosen under load and add undesirable weight, bulk, and complexity
Solution Approach 1:
The patent removes traditional closing mechanisms (belts, hooks, clips, laces) entirely and replaces them with an elastic band integrated into the garment structure. The elastic band is configured to receive a drawstring that can be pulled to constrict the waistband and leg loops, eliminating the need for separate fastening hardware while maintaining adjustability and improving reliability under load.
Solution Approach 2:
The patent combines the closing mechanism with the garment structure itself by integrating the elastic band into the waistband and leg loop construction. This merging eliminates the need for separate external fastening components and creates a unified structure where the elastic band and drawstring work together as an integrated closing system.
2Adaptability or versatility
If traditional closing mechanisms (belts, hooks, clips, laces) are used to constrict waistbands and leg loops, then the garment can be adjusted to fit different sizes, but the mechanisms add undesirable hardware, weight, and bulk
Solution Approach 1:
The patent removes traditional closing mechanisms (belts, hooks, clips, laces) entirely and replaces them with an elastic band integrated into the garment structure. The elastic band is configured to receive a drawstring that can be pulled to constrict the waistband and leg loops, eliminating the need for separate fastening hardware while maintaining adjustability and improving reliability under load.
Solution Approach 2:
The patent uses simple, lightweight materials such as elastic band and drawstring instead of heavy metal hardware. These components are inexpensive, easy to manufacture, and can be easily replaced if needed, providing a cost-effective and lightweight closing solution.
3Adaptability or versatility
If traditional closing mechanisms (belts, hooks, clips, laces) are used to constrict waistbands and leg loops, then the garment can be adjusted to fit different sizes, but the mechanisms are difficult to use and limit movement
Solution Approach 1:
The patent employs an elastic band that dynamically adapts to the wearer's movements and body shape. The elastic material automatically adjusts tension as the wearer moves, eliminating the need for manual adjustment mechanisms and providing continuous adaptability without limiting movement. The drawstring can be easily pulled to adjust the fit, and the elastic band maintains tension automatically.
4Adaptability or versatility
If traditional closing mechanisms (belts, hooks, clips, laces) are used to constrict waistbands and leg loops, then the garment can be adjusted to fit different sizes, but the mechanisms increase the bulk of the garment
Solution Approach 1:
The patent removes traditional closing mechanisms (belts, hooks, clips, laces) entirely and replaces them with an elastic band integrated into the garment structure. The elastic band is configured to receive a drawstring that can be pulled to constrict the waistband and leg loops, eliminating the need for separate fastening hardware while maintaining adjustability and improving reliability under load.
Solution Approach 2:
The patent uses thin, flexible elastic band material instead of bulky hardware components. The elastic band can be easily integrated into the garment structure with minimal added bulk, providing a sleek and streamlined appearance while maintaining full adjustability functionality.
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
The system provides a user-selectable waist or leg loop size that is reliably retained, offering easy adjustment without additional weight or bulk, and enhancing movement and flexibility.
Implementation Method 1
The constrict-able tubular length is configured to constrict about the line portion to retain the selected size of the closable circumference
Data Source
AI summary
Various example harness leg loops may include a flexible perimeter defining a closable circumference. The size of the closable circumference is maintained by a constricting tube in tension and is adjustable by releasing the constricting tube from tension.
