Segmented Football Boot Stud with Elastic Strain Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing studded shoes face a trade-off between traction and flexibility, as the attachment of studs increases the rigidity of the sole, making it difficult to achieve both good traction and flexibility, especially in the bending area of the shoe, which affects athletic performance.
Innovation Solution
The design incorporates a stud with a first and second stud portion connected by a strain section that adapts to the bending of the shoe sole, allowing for improved traction and flexibility by enabling the stud to strain and adapt to ground conditions without reducing comfort, even under great forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If studs are attached to the shoe sole, then traction is improved, but flexibility in the bending area deteriorates
Solution Approach 1:
The stud is divided into multiple stud portions (first stud portion, second stud portion, etc.) connected by strain sections. This segmentation allows each portion to independently adapt to ground conditions while maintaining overall structural integrity, resolving the contradiction between traction and flexibility.
Solution Approach 2:
The strain sections are designed to be elastically deformable, allowing the stud structure to dynamically adapt its shape in response to bending forces and ground reactions. This dynamic behavior enables the stud to maintain both traction contact with the ground and flexibility to accommodate shoe sole bending.
2Power
If rigid studs are used, then power transmission is improved, but comfort in the bending area deteriorates
Solution Approach 1:
By segmenting the stud into rigid stud portions and flexible strain sections, the design enables effective power transmission through the rigid portions while the flexible strain sections absorb bending stresses, maintaining comfort during athletic movements.
Solution Approach 2:
Different parts of the stud have different mechanical properties - the stud portions are rigid for effective ground contact and power transmission, while the strain sections are flexible to accommodate bending and maintain comfort. This local differentiation resolves the contradiction between power transmission and comfort.
3Stability of the object's composition
If multiple studs are connected via rigid elements, then stability is improved, but adaptability to ground conditions deteriorates
Solution Approach 1:
The strain sections provide dynamic flexibility that allows the stud assembly to adapt its configuration in response to varying ground conditions, while the overall structure maintains stability through the interconnected stud portions.
