Bicycle Valve Stem Support Bracket with Thumb Screw Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire valve devices integrated into bicycle wheels are not easily engaged or disengaged for use with a pump and lack an adjustment mechanism for compatibility with different valve types.
Innovation Solution
A bracket with a valve aperture and screw apertures, secured by thumb screws, which can be adjusted to fit various rim sizes and valve types, including a separate adjuster plate for thinner valves, allowing secure attachment to the bicycle rim and easy engagement with a pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If valve devices are integrated into the wheel or tire, then they provide stable valve support, but they are not easily engaged or disengaged for use with a pump
Solution Approach 1:
The valve support device is divided into a bracket portion that attaches to the rim and a valve holder portion that can be independently engaged and disengaged. This segmentation allows the valve holder to be easily removed for pump access while the bracket remains securely attached to the rim, resolving the contradiction between ease of operation and stability.
2Adaptability or versatility
If a fixed bracket design is used, then the structure is simple, but it lacks adjustment capability for different valve types and rim sizes
Solution Approach 1:
The bracket includes an adjustable arm with movable positioning features that allow the bracket to adapt to different rim sizes and valve types. This dynamic adjustment capability enables versatility without requiring multiple fixed bracket designs, balancing adaptability with manageable complexity.
Solution Approach 2:
The bracket is designed with universal features including multiple screw aperture positions and an adjustable arm that can accommodate various rim diameters and valve stem types. This multi-functionality allows a single bracket design to serve multiple purposes across different bicycle configurations.

AI summary
A valve stem support apparatus for supporting a valve stem while attached to a pump includes a bracket having a bracket top side, a bracket right side and a bracket left side. The bracket top side has a valve aperture extending therethrough. The valve aperture slidingly receives a valve stem of a tire of a bicycle. Each of the bracket left side and the bracket right side has a screw aperture extending therethrough. A receiving distance between the bracket right side and the bracket left side is wider than a rim of the bicycle. A pair of thumb screws is coupled to the bracket. The pair of thumb screws is threadingly engaged with the screw apertures of the bracket left side and the bracket right side to engage the rim of the bicycle and secure the bracket.
