Roller Blade Ice Wheel Assembly with Toe Rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller blade ice adaptor devices often require replacement of the wheel frame and lack a toe rack, limiting their functionality and compatibility with standard roller blades.
Innovation Solution
A roller blade ice adaptor device featuring blade wheel apparatuses with a central aperture, bearings, and spacers that attach to the roller blade axle, along with a toe rake and toe stopper apparatus for enhanced functionality and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a skating blade is added to the boot rather than using ice wheels, then the device can be used on ice, but the wheel frame must be replaced which increases device complexity and reduces compatibility with standard roller blades
Solution Approach 1:
The ice wheel assembly is segmented into separate components: a wheel body, a bearing assembly with axle, and spacer components. This segmentation allows the ice wheel to be attached to the existing roller blade wheel frame without replacing the entire frame, maintaining compatibility while enabling ice usage.
Solution Approach 2:
The bearing assembly is nested within the wheel body, with the axle passing through both components. The spacer components are positioned between the bearing assembly and the wheel frame, creating a nested structure that integrates multiple functions within a compact arrangement, eliminating the need for frame replacement.
2Ease of operation
If existing ice adaptor devices are used, then ice skating is enabled, but they lack a toe rack which reduces control and maneuverability
Solution Approach 1:
The toe rack is merged with the boot structure, forming an integrated assembly where the toe rack serves both as a structural support and as a control element for maneuverability. This combination adds functionality without requiring separate independent components.
Solution Approach 2:
The toe rack serves multiple functions: it provides structural support for the boot, enables control during ice skating maneuvers, and maintains compatibility with standard roller blade boots. This multi-functionality improves ease of operation without proportionally increasing device complexity.
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
Enables the use of roller blades on ice without replacing the wheel frame and provides a toe rack for improved control and maneuverability, ensuring compatibility with standard roller blades.
Implementation Method 1
At least one bearing is coupled to the wheel body. The bearing is configured to receive an axle of a roller blade through a bearing aperture and the wheel aperture.

AI summary
A roller blade ice wheel assembly for using roller blades on ice includes a plurality of blade wheel apparatuses each comprising a wheel body having a central wheel aperture, a pair of wheel sidewalls, and a wheel edge. The wheel edge is less than 0.5 cm. At least one bearing is coupled to the wheel body. The bearing receives an axle of a roller blade through a bearing aperture and the wheel aperture. Each of a plurality of spacers has a central spacer aperture to receive the axle of the roller blade. The plurality of spacers is positioned on both sides of the bearing to occupy space up to a wheel frame of the roller blade. The width of the blade wheel apparatus is dimensioned to equal the width of a wheel of the roller blade that is being replaced.
