Trouser Crease Stabilization via Shoe-Contact Slit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart trousers with a crease down the front leg often move sideways and twist due to lack of support, making the crease appear uneven, and existing solutions like strings or metal rings cause discomfort and are impractical.
Innovation Solution
A trouser leg design featuring a slit positioned on either side of the shoe, incorporating a stiffening element that resists lateral movement, with angled edges and a short length to ensure contact with the shoe, maintaining the crease's vertical alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stiffening element is added to stabilize the trouser leg, then the crease straightness is improved, but the comfort and practicality deteriorate due to strings or metal rings causing discomfort and irritation
Solution Approach 1:
The invention extracts the harmful aspects (strings, metal rings) from the stabilizing function and replaces them with a slit structure integrated into the trouser leg fabric itself. The slit incorporates a stiffening element that provides stability without requiring separate components that contact and irritate the wearer's skin.
Solution Approach 2:
The slit and stiffening element are merged into the trouser leg structure itself, combining the stabilizing function with the fabric construction. This integration eliminates the need for separate strings or rings, providing stability while maintaining comfort through a unified design.
2Ease of operation
If the trouser leg hangs loosely for comfort, then the ease of wear is improved, but the stability deteriorates causing sideways movement and twisting
Solution Approach 1:
The trouser leg maintains loose fabric for comfort in most areas, but the slit incorporates a stiffening element that provides localized structural support. This local reinforcement prevents lateral movement and twisting at the critical lower leg region while preserving the overall loose fit and comfort of the trouser leg.

AI summary
A trouser leg comprising a slit that incorporates a stiffening element, the slit being positioned such that, in use, the slit sits either side of a wearer's shoe, which stabilises the stiffening element and causes it to resist lateral movement of the trouser leg above the shoe.
