Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible skis face issues with the U-shaped covering part causing stress and potential detachment, increased standing height, and difficulty in mounting ski bindings, which affect performance and usability.
Innovation Solution
A collapsible ski design featuring a front and rear part connected pivotally around a transversal axis with a connecting platform, allowing for detachable assembly and disassembly without tools, enabling uniform bending and easy binding mounting, while maintaining performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a U-shaped covering part is used to cover the front and rear parts of the ski, then the structural integrity is improved, but the standing height is increased and the weight and rigidity are increased
Solution Approach 1:
The patent removes the U-shaped covering part from the ski structure, extracting the problematic element that caused increased standing height, weight, and rigidity while maintaining structural integrity through alternative means
Solution Approach 2:
The ski is divided into separate front and rear parts that are pivotally connected, allowing each part to be optimized independently without requiring a covering structure to maintain integrity
2Adaptability or versatility
If the front part and rear part are pivotally connected with each other, then the collapsibility is improved, but the rigidity in the central region is increased
Solution Approach 1:
The ski employs a dynamic pivotal connection that allows the front and rear parts to rotate relative to each other, enabling the structure to transition between collapsed and extended states while maintaining appropriate rigidity through the pivot mechanism itself
3Reliability
If the covering part is firmly fixed onto the surface of the ski, then the reliability is improved, but the manufacturing complexity is increased
Solution Approach 1:
The patent eliminates the covering part entirely, removing the complex attachment requirements and high-stress fixation points that complicated manufacturing while maintaining structural reliability through the simplified pivotal connection design

AI summary
A collapsible ski includes a front part and a rear part that, when arranged in their linearly aligned position, are fixed in that position by a connecting platform which is rotatable around an axis, which extends throughout a fold between the front part and rear part, and which is rectangular. Benefits of such a collapsible ski may include, to a consumer, practical storage and transporting benefits, while to the manufacturer, may include simplification of technology for manufacturing of each component, when compared with manufacturing of classic single-part skis. The collapsible ski can be assembled in place simply without using any tools. The collapsible ski is assembled of several mutually connectable yet detachable parts. The collapsible ski also provides the possibility of combining separately manufactured and preferably standardized parts in view of providing semi-products and finalizing each collapsible ski.
