Zipperless Length Adjuster for Protective Pant Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional protective pants for sports like hockey are often oversized and require frequent replacement due to growth, leading to inconvenience and expense for players.
Innovation Solution
A protective pant design featuring a zipperless length adjuster with multiple adjustment elements on both the inner and outer shells, allowing for adjustable length without zippers, ensuring a secure fit as the player grows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional oversized protective pants are used, then impact protection is provided, but the pants require frequent replacement due to player growth
Solution Approach 1:
The protective pant incorporates adjustable length mechanisms including a drawstring at the waist and adjustable straps at the legs, allowing the pant to dynamically adapt its fit as the player grows. This dynamic adjustment capability extends the service life of the pant while maintaining consistent protective function.
2Reliability
If traditional oversized protective pants are used, then impact protection is provided, but replacement becomes expensive and inconvenient
Solution Approach 1:
The adjustable features (drawstring, straps) allow the pant to be resized and reused multiple times as the player grows, eliminating the need for frequent expensive replacements while maintaining adequate fit and protection.
3Duration of action of stationary object
If adjustable length mechanisms are added, then the pant can be reused longer, but device complexity increases
Solution Approach 1:
The adjustment mechanisms modify the physical parameters (length, circumference) of the pant through simple mechanical means (drawstring tension, strap positioning) rather than complex systems, achieving extended service life with minimal added complexity.
Solution Approach 2:
The use of flexible drawstrings and straps provides continuous adjustability through simple textile elements rather than rigid mechanical components, maintaining simplicity while enabling long-term adaptability.

AI summary
A protective pant for a wearer, comprising a pelvic portion for overlying a pelvic region of the wearer to provide impact protection to the pelvic region, leg portions for overlying thighs of the wearer to provide impact protection to the thighs, and a zipperless length adjuster configured to adjust a length of the protective pant. Also, a protective pant for a wearer, the protective pant comprising: an inner base for protecting a pelvic region of the wearer; an outer shell; and a zipperless length adjuster comprising a plurality of adjustment elements on the inner base and a plurality of adjustment elements on the outer shell, each of the adjustment elements on the outer shell configured to be attachable to a corresponding one of the adjustment elements of the inner base in at least two positions to permit length-wise adjustment of the outer shell relative to the inner base.
