Air Chuck Swivel Head for Motorcycle Valve Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern motorcycles with smaller rim sizes and larger brake rotors present a challenge in accessing the tire valve due to limited space, leading to inefficient air chuck alignment and potential user injury from heat or other hazards.
Innovation Solution
An air chuck with a swivel head that allows for a range of angles, enabling easier access and alignment with the tire valve, reducing the risk of injury and improving sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed angle head air chuck is used, then the structure is simple, but the alignment with the valve stem is difficult when rim size is small and brake rotor is large
Solution Approach 1:
The air chuck head is made swivelable rather than fixed, allowing it to rotate and adjust to different angles. This dynamic adjustment enables the head to align properly with the valve stem even when access space is limited by small rims and large brake rotors, directly resolving the alignment difficulty without requiring complex external positioning mechanisms.
Solution Approach 2:
The air chuck is divided into separable components: a handle portion and a head portion connected by a swivel mechanism. This segmentation allows the head to independently rotate and orient itself relative to the handle, providing the necessary flexibility for alignment while keeping the overall structure relatively simple.
2Manufacturing precision
If the air chuck head is forced into alignment, then alignment may be achieved, but user injury risk increases due to heat from brake rotor or other hazards
Solution Approach 1:
The swivel mechanism allows the head to dynamically adjust its angle to achieve proper alignment with the valve stem. This eliminates the need for users to force the air chuck into position, thereby avoiding contact with hot brake rotors or other hazardous areas, while still achieving the required nozzle-to-valve alignment precision.
3Object-affected harmful factors
If the air chuck handle is positioned to avoid the brake rotor, then safety is improved, but the head cannot attach squarely to the valve stem
Solution Approach 1:
By separating the handle portion from the head portion with a swivel mechanism, the invention allows the handle to be positioned in a safe location away from the brake rotor while the head independently orients itself to attach squarely to the valve stem. This segmentation decouples the positional constraints of the handle from the alignment requirements of the head.
Solution Approach 2:
The swivel mechanism provides dynamic adjustment capability, allowing the head to rotate and find the correct alignment angle with the valve stem even when the handle is positioned at a safe distance from the brake rotor. This resolves the conflict between safety positioning and proper attachment alignment.
4Adaptability or versatility
If a swivel head mechanism is added, then alignment flexibility is improved, but the device complexity increases
Solution Approach 1:
A swivel mechanism is incorporated at the connection between the handle and head, allowing the head to rotate freely to achieve various approach angles. This single rotational degree of freedom provides the necessary adaptability for different valve positions while adding minimal structural complexity compared to more complex articulated or telescopic mechanisms.
