Solution Overview

Problem

Current rollerblades either require an additional pair of shoes when removed or have a liner that does not match with street clothes, and they are not easily storable due to their size.

Innovation Solution

A rollerblade design featuring a boot binding system with a pivoting upper rod and tensioning system that allows for easy boot insertion and removal, and the ability to fold for compact storage, accommodating various shoe models and facilitating storage in a bag.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a removable liner is provided that can be extracted from the footwear element, then it is not necessary to provide an additional pair of shoes, but the liner used as a shoe is not always matched to the clothing

Engineering Contradiction:
Improveshoe compatibilityVSAvoidliner appearance matching
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The footwear element is designed to accommodate multiple types of shoes (sports shoes, town shoes, boots) through a universal binding system that can adapt to different shoe models and styles, allowing one liner to serve multiple fashion purposes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If the upper rod is rigidly fixed to the support plate, then the structure is stable, but the rollerblade cannot be folded for compact storage

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The upper rod is designed with a pivoting mounting that allows it to rotate between a vertical position during use (providing structural stability) and a folded position during storage (reducing volume), enabling the structure to adapt its configuration based on operational needs

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the upper rod is made pivotable for easy boot insertion and removal, then ease of operation is improved, but the structure becomes more complex

Engineering Contradiction:
Improveboot insertion easeVSAvoidmounting system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pivoting upper rod provides easy boot insertion and removal by allowing the upper rod to rotate to a horizontal position for access, then returns to vertical for use, simplifying the operation without requiring complex mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tensioning system automatically tightens the filiform part when the upper rod is in the vertical position, providing self-adjustment and retention without requiring additional manual operations or complex control mechanisms

Inventive Principle:
Principle #25Self-service

AI summary

The roller (1) has a support plate (4) that is fixed above a chassis (2) by a fixation unit (6) e.g. screw nut, and an upper rod (10) mounted pivotingly toward rear part with respect to the support plate. A front rod (13) is equipped with a plating device (35) plating against an instep (15) of a shoe (9), where the shoe has a strap (36) passing through two openings arranged directly or indirectly respectively on lateral sides (18) of the support plate. Two ends of the strap are subjected to the upper rod.
