Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sharpeners for snow/ice travel members like ice skates, skis, and snowboards face challenges in accommodating blades of different thicknesses, ensuring even sharpening of left and right corners, and have difficult or expensive sharpening surfaces to replace.
Innovation Solution
A portable sharpener with a motorized or manual drive mechanism that includes adjustable sharpening surfaces and side face guide structures to center and sharpen blades of varying thicknesses, featuring a disposable sharpening base for easy replacement and consistent edge sharpening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed sharpening surfaces are used, then sharpening consistency is improved, but adaptability to different blade thicknesses deteriorates
Solution Approach 1:
The sharpening surfaces are made adjustable rather than fixed. The guide structures can be repositioned along the blade to accommodate different thicknesses, while the sharpening surfaces themselves can be replaced independently. This dynamic configuration allows the system to adapt to various blade dimensions while maintaining sharpening consistency through standardized surface geometry.
Solution Approach 2:
The sharpener is divided into separate functional components: guide structures for positioning, sharpening surfaces for the actual sharpening action, and adjustment mechanisms. This segmentation allows the guide structures to be adjusted for different blade thicknesses while the sharpening surfaces remain standardized for consistent performance.
2Adaptability or versatility
If complex adjustment mechanisms are added to accommodate different blade thicknesses, then adaptability is improved, but device complexity increases
Solution Approach 1:
The guide structures serve multiple functions: they guide the blade into proper positioning, provide reference surfaces for alignment, and enable adjustment for different thicknesses. This multi-functionality reduces the need for separate adjustment mechanisms, simplifying the overall device while maintaining adaptability.
Solution Approach 2:
The guide structures are designed to self-adjust or self-position based on the blade thickness. The user simply places the blade in the guide, and the structure automatically accommodates the thickness variation without requiring complex manual adjustments or multiple components.
3Ease of repair
If sharpening surfaces are made replaceable, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The sharpening surfaces are designed as replaceable, consumable components that can be easily swapped when worn. These surfaces are made from durable but replaceable materials, allowing users to replace only the worn surfaces rather than the entire sharpener unit, simplifying maintenance while keeping the overall device structure relatively simple.
Solution Approach 2:
The sharpening surfaces are extracted as separate, removable components from the main sharpener body. This allows the surfaces to be replaced independently without affecting the guide structures, adjustment mechanisms, or other components, simplifying the replacement process while maintaining device integrity.
4Device complexity
If manual operation is used, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The sharpener is designed to be manually operated without requiring complex motorized mechanisms. The user manually moves the sharpening surface along the blade, and the guide structures ensure proper positioning throughout the motion. This self-guided manual operation eliminates the need for motors, controllers, or automated mechanisms, keeping the device simple while still achieving effective sharpening.

AI summary
In one aspect, the invention is directed to a sharpener for sharpening a snow/ice travel member such as a skate blade, a ski or a snowboard, which includes a sharpening surface that is movable lengthwise along an edge face of the item to be sharpened. The sharpening surface may be movable lengthwise by means of a motor and a reciprocating mechanism, or may be manually moved by a user.
