Ski Boot Lateral Strap for Enhanced Turning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ski boots primarily focus on enhancing the transmission of forward/backward leg movement, which is less relevant for novice and recreational skiers, and do not effectively optimize lateral movement transmission, crucial for maintaining balance and turning performance, especially on icy surfaces.
Innovation Solution
A combination of a ski boot with a strap that extends from the lateral side of the hard outer shell, adjustable to hold the compressible inner liner in a relatively fixed position, providing enhanced lateral stability and responsiveness during skiing maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the ski boot focuses on enhancing forward/backward movement transmission, then the forward pressure transmission is improved, but the lateral movement transmission is insufficient
Solution Approach 1:
The invention divides the movement transmission function into two separate systems: a power strap for forward/backward movement transmission and a lateral strap for lateral movement transmission. This segmentation allows each strap to be optimized for its specific function without compromising the other, resolving the contradiction between forward pressure transmission and lateral movement transmission.
Solution Approach 2:
The lateral strap is positioned specifically at the lateral side of the boot, creating a localized structure that enhances lateral movement transmission without affecting the forward/backward transmission system. This local quality approach allows the boot to have different functional characteristics in different directions.
2Ease of operation
If the inner boot liner is compressible for comfort, then the comfort is improved, but the lateral stability is reduced
Solution Approach 1:
The lateral strap acts as a flexible constraint that maintains the compressible nature of the inner boot liner for comfort while providing lateral stability. The strap flexes with the liner's compression but prevents excessive lateral movement, resolving the contradiction between comfort and lateral stability.
Solution Approach 2:
The combination of the compressible inner boot liner material and the lateral strap creates a composite structure that exhibits both comfort (from the compressible liner) and lateral stability (from the strap constraint). This composite approach allows both properties to coexist.
3Adaptability or versatility
If the strap is tightened to hold the inner liner in fixed proximity, then the lateral performance is improved, but the adaptability for different positions is reduced
Solution Approach 1:
The lateral strap incorporates an adjustable mechanism that allows the strap tension to be dynamically changed. This enables the strap to be tightened for lateral performance when needed and loosened for entry or storage, resolving the contradiction between lateral performance and adaptability for different positions.

AI summary
A combination of a ski boot and a strap where the strap extends from an attachment point on the lateral side of a hard outer shell of the boot and in use is tightened to hold the inner boot liner in relatively fixed proximity to the lateral side of the outer boot shell during skiing. The strap can extend around the inner boot liner, or be at least partially incorporated as a part of the inner boot liner. In either case, the strap is adjustable between the tightened position, and an open position.
