Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of wheel holders for vehicle measurement is complex and difficult due to the lack of a special carrying handle, requiring two-handed operation and risking incorrect assembly, which can lead to inaccurate measurement results.
Innovation Solution
A wheel holder with radially extending arms featuring movable elements and a locking mechanism, including a carrying handle with integrated locking and unlocking elements, allowing for one-handed operation and secure attachment to a wheel with adjustable diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wheel holder is designed without a dedicated carrying handle and integrated locking mechanism, then the device structure remains simple, but the handling and mounting process becomes complex requiring two-handed operation
Solution Approach 1:
The carrying handle is merged with the locking mechanism into a single integrated component. The handle serves dual functions: carrying the wheel holder and actuating the locking mechanism to secure the arms to the wheel. This combination eliminates the need for separate locking components and enables one-handed operation throughout the mounting process.
Solution Approach 2:
The carrying handle is designed as a multi-functional element that performs multiple operations: it serves as the carrying grip during transport, the actuating lever for locking the arms, and the operational interface for securing the wheel holder to the wheel. This universal design reduces the number of separate components needed.
2Productivity
If the wheel holder requires two-handed operation for mounting, then the structural design can be simpler, but the installation time and complexity increase
Solution Approach 1:
The wheel holder is designed to be serviced and secured by a single operator without requiring assistance from a second person. The integrated handle allows one person to simultaneously hold the device and actuate the locking mechanism, making the system self-sufficient for one-handed operation throughout the installation process.
3Adaptability or versatility
If the arms have fixed length, then the manufacturing is simpler, but the adaptability to wheels of different diameters is reduced
Solution Approach 1:
The arms are designed with movable elements that can change length dynamically. The locking mechanism secures these movable elements at specific positions, allowing the arm length to be adjusted to match different wheel diameters. This dynamic adjustment capability provides versatility while maintaining secure attachment through the locking mechanism.
4Manufacturing precision
If the movable elements are not mechanically coupled to move synchronously, then the structure is simpler, but the accuracy of diameter adjustment is reduced
Solution Approach 1:
The movable elements are mechanically coupled through a coupling mechanism that ensures they move synchronously when one element is adjusted. This coupling maintains the symmetrical relationship between opposing arms, ensuring accurate diameter adjustment. The locking mechanism then secures the elements in their adjusted positions.

AI summary
The invention relates to a wheel holder (2) for fastening to a wheel (1), particularly to a wheel (1) of a motor vehicle, comprising at least two arms (22, 23, 24), which extend outward from a center (28) of the wheel holder (2) in a radial direction. Each of the arms (22, 23, 24) has at least one movable element (32, 33, 34), which is movable in the radial direction. The wheel holder (2) comprises a locking element (82), which is designed such that the movable elements (32, 33, 34) can be fixed such that the movable elements (32, 33, 34) are no longer movable in the radial direction, by actuating the locking element (82). The wheel holder (2) also comprises an unlocking element (84), which is designed such that the fixing of the movable elements (32, 33, 34) can be released by actuating the unlocking element (84).
