Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional roller skates are inconvenient to put on and take off due to the need for shoelaces to tighten the boot.

Innovation Solution

An easy-wearing skate design featuring a boot with a fixed and movable shell, where the movable shell is rotatably connected to the fixed shell and secured by a tightening strap and locking device, allowing for easy release and retraction to facilitate quick donning and doffing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a shoelace tightening system is used in conventional roller skates, then the boot can be securely fastened, but the process of putting on and taking off the skate becomes inconvenient and time-consuming

Engineering Contradiction:

Improveease of wearing and removalVSAvoidtime required to tighten and loosen shoelaces

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The skate shell is divided into a fixed shell and a movable shell that can rotate relative to each other. The movable shell can swing from a closed position (covering the rear opening) to an open position (exposing the rear opening), enabling quick entry and exit of the foot without manual tightening or loosening of fasteners.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The boot is segmented into a fixed shell and a movable shell that can independently move. This segmentation allows the rear portion of the boot to be dynamically opened or closed, eliminating the need for continuous shoelace manipulation during wear removal.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the movable shell is rotatably connected to allow easy removal, then the skate can be quickly taken off, but the structural complexity increases with the addition of rotatable joints and locking mechanisms

Engineering Contradiction:

Improvequick removal capabilityVSAvoidstructural complexity of rotatable connection and locking device

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The locking function is merged with the rotational connection between the fixed shell and movable shell. The first tightening strap connects these two shells, and its tensioning action simultaneously achieves both the locking of the shells in position and the securing of the foot, eliminating the need for separate locking mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tightening strap system is designed to automatically lock when tensioned. The strap's tensioning action itself creates the locking effect through friction and geometric constraints, without requiring additional active locking components or complex mechanisms.

Inventive Principle:

Principle #25Self-service
