Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skate squaring devices are not effective for skate blades with different cross-sectional shapes, as they rely on the skate blade body for mounting and alignment, which limits their precision and adaptability.
Innovation Solution
A skate squaring device with a u-shaped main frame and magnetic attachment to a skate sharpening fixture, featuring calibration lines and a slot to accommodate various skate blade shapes, allowing precise squareness determination and adjustment indications for sharpening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art squaring devices use the skate blade body for mounting and alignment, then they can provide a mounting reference, but they cannot work precisely on all types of skate blades with different cross-sectional shapes
Solution Approach 1:
The patent introduces a flat reference surface that contacts the skate sharpening fixture anvil as an intermediary element. This reference surface serves as a mediator between the fixture and the blade, providing a consistent mounting plane that is independent of the blade's cross-sectional shape. The reference surface enables precise squareness determination by creating a stable geometric relationship with the fixture while accommodating various blade shapes through the slot opening.
2Adaptability or versatility
If a fixed mounting method is used for squaring devices, then the structure can be simple, but it cannot accommodate skate blades with different cross-sectional shapes
Solution Approach 1:
The device is segmented into distinct functional components: a U-shaped frame with legs, a reference surface, calibration lines, and a slot opening. This segmentation allows each component to perform its specific function independently - the legs provide structural support and mounting, the reference surface provides the mounting plane, and the slot accommodates different blade shapes. This modular segmentation achieves versatility without excessive complexity.
Solution Approach 2:
The reference surface serves multiple functions: it provides a mounting reference plane for the blade, establishes a geometric relationship with the fixture for squareness determination, and works with various blade shapes. The calibration lines on the legs also serve dual purposes by providing both structural definition and measurement reference. This multi-functionality reduces the need for additional components.
3Measurement precision
If calibration lines are placed on the skate blade body, then squareness can be indicated, but the device cannot be precisely applied to all blade types
Solution Approach 1:
The calibration lines are positioned on the vertical legs of the U-shaped frame, which is a different spatial dimension than the blade body surface. This dimensional relocation allows the calibration lines to serve as a fixed reference plane perpendicular to the reference surface, independent of the blade's cross-sectional geometry. The lines provide accurate squareness indication by comparing the blade edge against this fixed dimensional reference rather than relying on the blade body shape.

AI summary
A skate squaring device includes a main frame having a slot to receive a skate blade. The main frame is designed to attach to a portion of a skate sharpening fixture such that calibration lines on the main frame are perpendicular to a centerline axis of a body of the skate blade when mounted in the holder. A magnetic angle is attached to the end of the skate blade and positioned adjacent a face of the main frame having the calibration lines to determine if the skate blade edge is square.
