Shoe Heel Instep Pull System for Pressure-Free Foot Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mountain shoes face challenges in balancing foot hold and comfort, as existing deep-drawing devices primarily adapt the shoe shape to the instep and instep area, neglecting the ankle area, leading to local pressure and inadequate support.
Innovation Solution
The shoe incorporates a heel instep pull system with straps arranged in a V-shape, connecting to a locking device, allowing for individual adjustment and distribution of flexible and less flexible zones to secure the foot while maintaining natural movement, using a lacing system with deep-draw hooks or other closing elements for optimal fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional deep-drawing devices are used to adapt the shoe shape to the foot, then the instep and instep area are well supported, but the ankle area is neglected causing local pressure and inadequate support
Solution Approach 1:
The closing device is divided into multiple independent lacing sections: a first lacing section for the instep area and a second lacing section for the ankle area. This segmentation allows each section to independently adapt to different foot regions, providing comprehensive support without concentrating pressure in one area.
Solution Approach 2:
Different lacing sections are designed with specific functions tailored to their location: the first lacing section with deeper drawing capability for the instep area, and the second lacing section for the ankle area. This local differentiation ensures optimal support distribution matched to the anatomical requirements of each foot region.
2Stability of the object's composition
If the shoe provides firm foot hold through tight closing, then stability is improved, but comfort and natural movement are reduced
Solution Approach 1:
The lacing system incorporates adjustable tension across different sections, allowing the shoe to dynamically adapt to the foot's movement requirements. The multiple lacing sections can be independently adjusted to provide firm hold where needed while maintaining flexibility in movement areas, enabling the shoe to transition between stable and flexible states as required.
