Solution Overview

Problem

Existing skate replacement mechanisms are laborious, cumbersome, and pose safety risks due to the use of strong torsion springs and metal components, making it difficult for athletes to quickly and safely disassemble and assemble skates during competitions, especially in high-speed sports like ice hockey and figure skating.

Innovation Solution

A locking device for skates that uses a folding locking wrench to drive a gear on a driving shaft, enabling the clamping member to lock or release skate hooks within a skate bracket, with a locking part to prevent rotation and a pushing part to eject the hooks, eliminating the need for strong torsion springs and reducing the risk of accidental disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If strong torsion springs or high-hardness springs are used to firmly clamp the skate hook, then the locking reliability is improved, but the operation difficulty increases and safety risks arise during disassembly and assembly

Engineering Contradiction:
Improvelocking reliabilityVSAvoidoperation difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the fundamental parameter of the locking mechanism from elastic force (springs) to mechanical friction and geometric constraint. The clamping member uses a friction-based engagement system with the skate hook, eliminating the need for strong torsion springs. This parameter change reduces the operational difficulty while maintaining locking reliability through the design of the clamping groove and friction engagement.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts and removes the strong torsion spring component from the locking mechanism entirely. By taking out the elastic element that causes safety risks and operational difficulty, the design achieves a simpler, safer mechanism that relies on the clamping member's geometric design and friction engagement instead.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If metal springs or torsion springs are used to ensure firm clamping, then the locking strength is improved, but the corrosion resistance deteriorates in cold, rusty environments

Engineering Contradiction:
Improvelocking strengthVSAvoidcorrosion resistance
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent removes the metal spring components that are susceptible to corrosion in cold, rusty environments. By extracting the elastic metal elements, the design eliminates the corrosion problem while maintaining locking strength through alternative friction-based and geometric constraint mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs composite material strategies by combining friction-based engagement surfaces with geometric constraint features. The clamping member utilizes material properties optimized for friction engagement and geometric precision rather than relying on elastic metal springs, improving corrosion resistance while maintaining strength.

Inventive Principle:
Principle #40Composite materials

3Productivity

If the wrench is designed as an eccentric wheel for quick release, then the disassembly speed is improved, but the stability deteriorates due to accidental rotation during high-speed skating

Engineering Contradiction:
Improvedisassembly speedVSAvoidwrench stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent segments the wrench mechanism into distinct functional zones: a driving portion for engagement with the driving shaft, a clamping portion for operating the clamping member, and a stabilizing portion that prevents accidental rotation. This segmentation allows each part to optimize its function while maintaining overall stability during high-speed skating.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent incorporates preliminary anti-action measures through the stabilizing portion of the wrench, which is designed to prevent accidental rotation before it can occur during high-speed skating. The geometric design and friction engagement of the stabilizing portion create resistance to unintended movement, counteracting the harmful effect of accidental rotation.

Inventive Principle:
Principle #9Preliminary anti-action

4Strength

If ice residue is allowed to remain in the skate bracket, then the structural integrity is maintained, but the ease of operation deteriorates when removing skates

Engineering Contradiction:
Improvestructural integrityVSAvoidease of skate removal
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent incorporates a pushing member that performs preliminary action to eject ice residue from the cutter groove before the skate needs to be removed. This preliminary cleaning action prevents ice residue from interfering with the clamping member's operation, making skate removal easier while maintaining structural integrity during normal use.

Inventive Principle:
Principle #10Preliminary action
