Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cross-country ski bindings with multiple elastic flexors are complex, costly to manufacture, and prone to material fatigue, leading to oscillation issues during skating that disrupt forward movement.
Innovation Solution
A cross-country ski binding with an unyielding base body and an elastically deformable reset element, featuring an elevation behind the pivot axis to control the ski boot's position and limit oscillation, eliminating the need for a rear flexor and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple elastic flexors are used in the cross-country ski binding, then the oscillating movement of the ski is limited, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the rear flexor from the binding structure, keeping only the front flexor. The elevation behind the pivot axis compensates for the removed rear flexor by limiting the boot's upward pivot, thereby simplifying the structure while maintaining oscillation control functionality.
Solution Approach 2:
The patent introduces an elevation at a specific location (behind the pivot axis) with specific properties (unyielding, height of 0.3-1.5mm) to perform the function previously distributed to multiple flexors. This localized structural modification achieves oscillation control without adding overall device complexity.
2Stability of the object's composition
If multiple elastic flexors are used in the cross-country ski binding, then the oscillating movement is limited, but the manufacturing cost increases
Solution Approach 1:
By removing the rear flexor component entirely and replacing its function with a simple elevation integrated into the binding base body, the patent reduces the number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining oscillation control.
Solution Approach 2:
The elevation is integrated directly into the binding base body structure, merging two previously separate functions (base body support and oscillation limitation) into a single unified component, which simplifies manufacturing and reduces costs.
3Stability of the object's composition
If a rear flexor is used in the cross-country ski binding, then the oscillating movement is limited, but material fatigue occurs leading to impaired function
Solution Approach 1:
The patent removes the rear flexor, an elastic component prone to material fatigue, and replaces it with an unyielding elevation that does not undergo repeated elastic deformation. This eliminates the fatigue problem while maintaining the oscillation control function.
Solution Approach 2:
Instead of using an elastic element (flexor) to limit oscillation, the patent uses a rigid elevation that mechanically stops the boot's upward pivot. This inverts the approach from elastic deformation-based control to rigid geometric constraint, improving reliability.
4Ease of manufacture
If the cross-country ski binding is simplified by removing the rear flexor, then manufacturing cost decreases, but oscillation control may be compromised
Solution Approach 1:
The elevation is designed with specific local properties (height of 0.3-1.5mm, unyielding material) at the critical location behind the pivot axis to compensate for the removed rear flexor. This localized precision engineering ensures oscillation control is maintained despite the overall simplification.
Solution Approach 2:
The patent changes the parameter of the binding structure by introducing an elevation with specific height dimensions (0.3-1.5mm) and material properties (unyielding). This parameter modification allows the single front flexor system to achieve the same oscillation control as the previous dual-flexor system.
