Crampon with Embedded Cleats and Dual Elastomer Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crampons face a challenge in balancing effective traction and grip with comfort, as they often compromise between providing improved traction and being comfortable for the wearer.
Innovation Solution
A crampon design featuring a crampon base with cross-shaped cleats and angled spikes, embedded within a molded structure, combined with a flexible harness system using different elastomers for durability and comfort, and a Velcro strap for secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional crampons use separate attached cleats, then traction and grip are improved, but device complexity and potential discomfort increase
Solution Approach 1:
The cleat base is embedded within the crampon base structure, merging two previously separate components (cleat and crampon base) into a unified integrated structure. This eliminates the need for separate attachment mechanisms while maintaining the traction function through the embedded cleat design with spikes extending from the integrated base.
2Strength
If crampons use rigid structures for durability, then strength is improved, but comfort and flexibility deteriorate
Solution Approach 1:
The crampon employs different elastomers with different properties in different locations: a first elastomer for the crampon base providing durability and structure, and a second elastomer for the harness providing flexibility and comfort. This local differentiation of material properties allows each component to optimize for its specific functional requirements.
3Adaptability or versatility
If crampons use multiple separate components for functionality, then adaptability is improved, but ease of manufacture and comfort worsen
Solution Approach 1:
The cleat base is integrated within the crampon base through molding, combining multiple functional elements (traction cleat, structural base, attachment points) into a single manufacturable component. This reduces the number of separate parts that need to be manufactured and assembled, simplifying the manufacturing process while maintaining adaptability through the embedded cleat design.
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 enhances traction and stability while maintaining comfort by providing a secure fit and reducing weight, minimizing the risk of snow or ice accumulation and improving flexibility for easy use.
Implementation Method 1
The crampon base may comprise a first elastomer, and the harness may comprise a second elastomer different from the first elastomer. The first elastomer may be more durable and/or less flexible than the second elastomer.
Implementation Method 2
The connector may comprise a Velcro® strap.

AI summary
A crampon includes a crampon base for fitting to an underside of an item of footwear, such as a shoe or a boot. A harness extends from the crampon base and may be attached to the crampon base using rivets. The harness and the crampon base define a space for receiving the item of footwear. The crampon base comprises at least one cleat assembly with a cleat base embedded within the crampon base. One or more spikes extend from the cleat base.
