Solution Overview
Problem
Existing blade guards for ice skates are cumbersome to assemble, prone to rust, and do not provide stability for various blade types, leading to discomfort and potential injuries from springs and stagnant water issues.
Innovation Solution
A monolithic blade guard with a deformable bellows-like structure that adjusts to different blade sizes and types, featuring a longitudinal groove and pass-through openings to prevent rust and facilitate water drainage, eliminating the need for springs and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional blade guards use two separate pieces assembled with screwed springs to cover different blade sizes, then adaptability to various blade lengths is improved, but device complexity and ease of operation deteriorate due to assembly requirements and potential injuries
Solution Approach 1:
The blade guard is divided into multiple bellows sections along its longitudinal axis, each section capable of independent deformation. This segmentation allows the guard to adapt to different blade lengths while maintaining a simple monolithic structure without requiring separate pieces or assembly components.
Solution Approach 2:
The bellows structure provides dynamic adaptability through elastic deformation along the longitudinal axis. The guard can expand and contract to fit various blade sizes, replacing the static two-piece design with screwed springs. This dynamic feature is achieved through the geometric configuration of the bellows sections rather than mechanical fastening systems.
2Adaptability or versatility
If traditional blade guards use screwed springs for assembly, then adaptability is improved, but ease of operation and reliability worsen due to rusting and potential hand injuries
Solution Approach 1:
The harmful screwed springs are completely extracted from the blade guard design. The assembly operation is eliminated by using a monolithic bellows structure that naturally adapts to different blade sizes through deformation. This removes the source of rusting and potential hand injuries while maintaining adaptability.
Solution Approach 2:
The bellows structure performs the adaptation function automatically through its elastic deformation capability. The guard self-adjusts to fit different blade sizes without requiring manual assembly or disassembly operations. This self-service mechanism eliminates the need for screwed springs and associated reliability issues.
3Ease of manufacture
If blade guards have a standard housing design, then manufacturing simplicity is improved, but stability and firm hold for some blade types deteriorate
Solution Approach 1:
The bellows structure provides locally adaptive stability through its geometric configuration. Different sections of the bellows can deform independently to match the specific shape and dimensions of various blade types. This local adaptability ensures firm hold and stability for different blade configurations while maintaining a standardized manufacturing process for the overall guard structure.

Function Achieved in This Case
The solution provides a lightweight, aesthetically pleasing, and stable blade guard that is easy to use, adaptable to various blade lengths and types, while preventing rust and ensuring effective water drainage, thus improving user comfort and safety.
Implementation Method 1
the groove is formed in a bellows-like structure that is deformable, preferably elastically deformable, along the axis to vary the overall length of the element and the groove
Implementation Method 2
allows the housing of different types of blades and maintains the stability thereof during movement

AI summary
A blade guard is described for protecting the edges of an ice-skate blade. To manage more than one blade size, the blade guard consists of or comprises a monolithic element elongated along a longitudinal axis (X) and provided with a longitudinal groove for receiving the edges, wherein the groove is formed in a bellows-like-like structure that is deformable along the axis (X) to vary the overall length of the element and of the groove.
