Sports Shoe Little Toe Protection Structure for Squeeze Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports shoes lack adequate protection for the foot's little thumb, leading to issues such as redness, swelling, abrasion, and potential deformation due to squeezing forces during physical activities, particularly affecting adolescents and adults with active lifestyles.
Innovation Solution
A sports shoe design featuring a little thumb protection area with a bulging sole extension and a concave cavity, equipped with a flexible structure that includes a protective thin film, airbags, cushions, or a support plate with a silicone block to provide deformable buffering and flexible contact for the foot's little thumb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid protection structure is added to protect the little thumb, then protection effectiveness is improved, but comfort and flexibility deteriorate
Solution Approach 1:
The patent uses a flexible protective film (0.2-0.5mm thick) as the protection structure instead of rigid materials. This thin film can deform and adapt to the shape of the little thumb, providing protection while maintaining flexibility and comfort during sports activities
Solution Approach 2:
The patent changes the physical parameters of the protection structure by using a flexible material with specific thickness (0.2-0.5mm) that allows deformation. The protection structure is designed to change shape under pressure, transforming from a rigid barrier to a dynamic cushion that adapts to movement
2Ease of operation
If no protection structure is provided, then comfort and flexibility are maintained, but the foot's little thumb is vulnerable to squeezing injuries
Solution Approach 1:
The patent implements protection by placing a flexible protective film beforehand in the shoe upper at the little thumb area. This pre-positioned cushioning layer is designed to deform and absorb squeezing forces before they can injure the little thumb during sports activities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design offers flexible protection against squeezing forces, reducing discomfort and potential deformation, enhancing comfort, and suitability for various age groups and environments.
Implementation Method 1
A flexible structure for squeezing the foot's little thumb is provided between said little thumb protection area and the concave cavity
Implementation Method 2
provide deformable buffering when the foot's little thumb is squeezed during movement
