Detachable Roller Skate Locking Structure for Quick Shoe Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller skates are inconvenient to wear and carry due to their one-piece design, bulky size, and complex detachment processes, and they fail to provide a real skating experience with thin wheels and limited wheel spacing.
Innovation Solution
A detachable roller skating structure with a framework, locking mechanism, and tumbler switch that allows quick attachment and detachment to a regular shoe using buckles driven by a driving assembly, ensuring safety through self-locking and movement limiting assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If roller skates are designed as one-piece structure, then structural simplicity is achieved, but convenience for wearing and carrying deteriorates
Solution Approach 1:
The roller skate is divided into two independent parts: a shoe body and a skate assembly that can be detached. The shoe body contains a receiving cavity while the skate assembly includes a framework with buckles that engage with the shoe body. This segmentation allows the skate to be separated into wearable shoe portion and portable skate portion, resolving the contradiction between structural simplicity and wearing/carrying convenience.
2Ease of operation
If roller skates are made detachable, then convenience for changing and carrying is improved, but detachment and mounting processes become complicated
Solution Approach 1:
The locking mechanism employs reset elastic members that automatically return the buckles to their locked position after attachment. When the skate assembly is placed onto the shoe body, the elastic members self-generate restoring force to push the buckles into the locked state without requiring manual intervention, thereby simplifying the mounting process while maintaining detachability convenience.
3Reliability
If buckles are designed to lock securely, then safety is improved, but ease of detachment deteriorates
Solution Approach 1:
The locking mechanism uses dynamic elastic members that can transition between compressed and relaxed states. During normal use, the elastic members maintain continuous pressure to keep buckles securely locked. For detachment, the system allows the elastic members to be pushed inward against their restoring force, dynamically switching from locked to unlocked state. This dynamic behavior resolves the contradiction between secure locking and easy detachment.
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 convenient carrying and mounting of the roller skate, providing a real skating experience with stable wheel spacing and improved safety through self-locking and movement limiting features.
Implementation Method 1
the reset elastic member is in a compressed state when the buckle is in a locked state
Implementation Method 2
a compression spring disposed between the locking member and an inner wall of the housing, one end of the locking member distal to the compression spring is capable of being inserted into the locking hole under an action of the compression spring

AI summary
A detachable roller skating structure includes a framework, a locking mechanism, and a tumbler switch. The framework is provided with a receiving cavity, the locking mechanism is disposed in the receiving cavity, the locking mechanism includes two buckles and a driving assembly located between the two buckles, the driving assembly is linked to the tumbler switch on an outer side of the framework, and a limiting lock is disposed on the tumbler switch. According to the present application, the roller skating structure can be more conveniently detached from or mounted onto a sole of a regular shoe, achieving free change between the regular shoe and the roller skate. In addition, the self-locking of the roller skating structure is achieved by the arrangement of the limiting lock, and the use safety of the roller skates is improved.
