Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller skates with multiple wheels face difficulties on uneven surfaces due to small wheel size, leading to discomfort, instability, and lack of effective braking and fastening mechanisms.
Innovation Solution
A roller skate design featuring a single wheel with a first and second circular element, allowing the shoe to be positioned partially inside the wheel, combined with a brake system and adjustable connection means for improved stability and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single large wheel is used to handle uneven surfaces, then the ability to skate on rough terrain is improved, but the stability of the user is worsened due to raised support point
Solution Approach 1:
The wheel is segmented into two independent circular elements that can rotate relative to each other, allowing the connection means to be positioned lower while maintaining ground contact capability. This segmentation enables the shoe to be positioned inside the wheel structure, lowering the support point and improving stability without sacrificing terrain adaptability.
Solution Approach 2:
The connection means and shoe are nested inside the wheel structure, specifically within the space between and around the two circular elements. This nesting allows the support point to be lowered closer to the ground contact point, improving stability while the outer circular elements maintain the ability to handle uneven surfaces.
2Ease of operation
If the frame is mounted higher to reduce leg pressure, then comfort is improved, but stability is worsened due to raised support point
Solution Approach 1:
The wheel's segmented structure allows the connection means to be positioned at an optimal height that balances comfort and stability. The two circular elements provide structural support while enabling the connection means to be lower, preventing the frame from needing to be mounted high, thus maintaining both comfort and stability.
3Volume of moving object
If multiple small wheels are used, then the roller skate is compact, but the ability to handle uneven surfaces is worsened
Solution Approach 1:
Multiple small wheels are merged into a single wheel structure composed of two circular elements. This combination maintains the compact form factor of multiple small wheels while providing the ground contact capability of a larger wheel, enabling the skate to handle uneven surfaces without increasing overall size.
4Device complexity
If the shoe is positioned outside the wheel, then connection is simplified, but weight distribution is worsened causing lateral force on the leg
Solution Approach 1:
The shoe and connection means are nested inside the wheel structure, specifically within the space between the two circular elements. This positioning aligns the weight distribution vertically through the wheel's contact point, eliminating lateral forces on the leg while maintaining connection simplicity through the integrated design.
