Single-Pull Snowshoe Binding with Merged Arch and Heel Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snowshoe binding systems require twisting and bending motions to tighten the heel strap, which can be cumbersome and inefficient, especially when combined with tightening the toe and arch straps.
Innovation Solution
A snowshoe binding system where the heel strap is connected to the arch area strap, allowing a single pull to tighten both the arch and toe straps, with a loop handle formed by connecting the tail ends of these straps, and a flexible strap guide to maintain the heel strap in a horizontal position, enabling simultaneous tightening of all straps with a single pull.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heel strap is connected separately and tightened manually, then the heel strap can be adjusted independently, but the user must perform twisting and bending motions to tighten it, which is cumbersome and inefficient
Solution Approach 1:
The patent connects the heel strap to the arch area strap, merging two separate tightening operations into one. When the user pulls the arch area strap, it simultaneously tightens both the arch area and the heel strap, eliminating the need for separate manual adjustment of the heel strap.
Solution Approach 2:
The arch area strap serves multiple functions: it tightens the arch area region and simultaneously tightens the heel strap through the connection. This multi-functionality reduces the number of separate adjustment actions required from the user.
2Ease of operation
If the heel strap is positioned manually before tightening, then proper positioning can be achieved, but it requires additional manual positioning steps that reduce efficiency
Solution Approach 1:
The strap guide extension is pre-positioned on the binding shell to automatically guide and hold the heel strap in the correct position. This preliminary positioning action eliminates the need for the user to manually position the heel strap before tightening.
Solution Approach 2:
The strap guide extension and strap guide automatically perform the positioning function without user intervention. The heel strap is self-positioned by these guide structures as it is tightened, freeing the user to simply pull the strap.
3Productivity
If the arch area strap is fixed to the binding shell, then the structure is simple, but the heel strap cannot be tightened simultaneously with the arch strap
Solution Approach 1:
The heel strap and arch area strap are merged into a continuous strap structure. This allows a single pulling action on the arch area strap to simultaneously tighten both the arch region and the heel, doubling the productivity of the tightening operation.
Solution Approach 2:
While maintaining continuity, the strap is segmented into functional zones (arch area and heel areas) with guide structures at each zone to ensure proper routing and tightening. This segmentation allows simultaneous tightening while maintaining structural organization.
