Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stable positioning of two-wheeler wheels are limited by a narrow range of wheel radii and thicknesses, requiring additional support structures like walls, and often allow for free-play, compromising stability.
Innovation Solution
A device with movable positioning devices forming two support points, each connected to a bearing device on a rotational axis, ensuring balanced support through isosceles triangle brackets and adjustable frames, allowing for various wheel sizes and thicknesses without external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed positioning shoes with V-shaped channels are used, then the device is simple in structure, but it only supports a narrow range of wheel thicknesses and radii
Solution Approach 1:
The patent applies the dynamics principle by making the positioning shoes movable rather than fixed. The shoes are mounted on pivot axes allowing them to rotate, enabling automatic adaptation to different wheel dimensions. This dynamic adjustment mechanism resolves the contradiction by providing wide adaptability across wheel thicknesses and radii while maintaining relatively simple structural components.
Solution Approach 2:
The patent employs parameter changes by allowing the positioning shoes to change their angular position and orientation. By varying the rotation angle of each shoe about its pivot axis, the device adapts to different wheel parameters (thickness and radius). This enables a single device structure to accommodate multiple wheel specifications without increasing complexity.
2Adaptability or versatility
If multiple fixed shoes are used to support different wheel sizes, then the device structure becomes complex, but it still cannot accommodate all wheel variations
Solution Approach 1:
The patent uses dynamics by implementing movable shoes that can rotate about pivot axes. Instead of having multiple fixed shoes for different wheel sizes, the system uses fewer shoes that can dynamically adjust their position. This reduces the number of components while expanding the range of wheel radii that can be supported.
Solution Approach 2:
The patent applies universality by designing each positioning shoe to serve multiple functions through its ability to rotate and adjust. A single shoe can position wheels of various radii and thicknesses by changing its angular position, making the component universal rather than specialized for one wheel size.
3Reliability
If shoes are optimized for specific wheel dimensions, then positioning precision is high for those dimensions, but stability is compromised for other dimensions
Solution Approach 1:
The patent resolves this contradiction by making the shoes dynamic with rotational freedom about pivot axes. Each shoe can adjust its angle to match the specific wheel thickness, maintaining optimal contact and positioning stability for whatever wheel dimension is present, rather than being fixed for one specific dimension.
Solution Approach 2:
The patent uses parameter changes by allowing the positioning angle and orientation of each shoe to vary based on the wheel dimensions. This enables the system to maintain high positioning precision and stability across a wide range of wheel thicknesses by adjusting the geometric parameters of the shoe positions.
4Adaptability or versatility
If a rail with fixed support points is used, then the device structure is simple, but it only works for one wheel radius
Solution Approach 1:
The patent applies dynamics by replacing fixed rail support points with movable shoes on pivot axes. The shoes can rotate to accommodate different wheel radii, providing adaptability without requiring complex adjustable mechanisms. The simplicity is maintained through the use of simple rotational joints rather than complex adjustment systems.
