Ski Boot Shell Segmentation for Rigidity and Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports footwear structures, such as ski boots, are complex and difficult to assemble/disassemble, leading to reduced rigidity and increased wear-related slack, making them cumbersome to adapt to different sports or foot shapes and requiring complicated component replacement.
Innovation Solution
A sports footwear structure featuring separately made sidewalls and an outer hull that can be removably coupled to an insole and outsole using screws, allowing for easy assembly and disassembly, while maintaining rigidity and insulation through a simplified design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shell is made up of numerous components assembled together to adapt to different sport disciplines and foot shapes, then the adaptability is improved, but the device complexity increases and the rigidity decreases due to slack between interconnected parts
Solution Approach 1:
The shell is divided into a first shell portion and a second shell portion that can be selectively coupled together. This segmentation allows the boot to be adapted to different sport disciplines and foot shapes by choosing which portions to assemble, while maintaining simplicity because only two main segments are involved rather than numerous components.
2Adaptability or versatility
If numerous components are assembled together to provide adaptability, then the adaptability is improved, but the ease of operation deteriorates due to complicated assembly and disassembling
Solution Approach 1:
The shell is divided into a first shell portion and a second shell portion that can be selectively coupled together. This segmentation allows the boot to be adapted to different sport disciplines and foot shapes by choosing which portions to assemble, while maintaining simplicity because only two main segments are involved rather than numerous components.
3Adaptability or versatility
If numerous components are interconnected to provide adaptability, then the adaptability is improved, but the reliability deteriorates due to increased wear-related slack
Solution Approach 1:
The shell is divided into a first shell portion and a second shell portion that can be selectively coupled together. This segmentation allows the boot to be adapted to different sport disciplines and foot shapes by choosing which portions to assemble, while maintaining simplicity because only two main segments are involved rather than numerous components.
4Strength
If the two half shells are permanently fastened to each other to create a rigid structure, then the rigidity is improved, but the ease of repair deteriorates as component replacement becomes difficult
Solution Approach 1:
The coupling between the first and second shell portions is made dynamic rather than fixed. The first shell portion includes a coupling element that can selectively engage with the second shell portion, allowing the structure to transition between coupled and uncoupled states. This enables easy replacement and repair of components while maintaining rigidity when coupled.

AI summary
The present invention refers to a sports footwear structure or a sports footwear component, in particular a shell designed to enclose the foot of a user, comprising an outsole (9) and an insole (4) which includes a foot support surface. At the opposite edges of the insole (4) are removably associated a first sidewall (2) and a second sidewall (3) to form a sub-assembly. An outer hull (8), which includes the outsole (9) and is suitable to hold the sub-assembly, is removably connected to the lower surface of the insole (4) opposite the foot support surface.
