Portable Compressor Suspension for Tire Valve Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable compressor devices for inflating motor vehicle tires are cumbersome and difficult to use, especially in unfamiliar situations, as they require carrying a spare wheel and multiple tools, and have complex hose connections that are prone to misplacement or incorrect assembly, leading to inefficient repair processes and increased packing size due to long hoses.
Innovation Solution
A portable compressor device with a releasable mechanical connection to the tire valve, allowing it to 'hang' independently of the ground, eliminating the need for separate hose connections and ensuring all components are in the correct position for easy operation, featuring a short hose and intuitive screw cap or loop connections for secure attachment and alignment of operating elements towards the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a long hose is used to connect the compressor to the tire valve, then the compressor can be placed on the ground next to the tire, but the packing size increases and the device becomes more cumbersome
Solution Approach 1:
The compressor is suspended from the tire valve in a vertical dimension rather than being placed on the horizontal ground surface. This dimensional change eliminates the need for a long hose while maintaining operational accessibility, as the compressor hangs close to the tire without requiring ground contact.
Solution Approach 2:
The hose connection is extracted and replaced by a direct mechanical suspension system. The compressor is attached directly to the valve assembly through a holder or loop, removing the intermediate hose element that previously connected the ground-placed compressor to the tire valve.
2Adaptability or versatility
If multiple separate components and tools are carried for tire repair, then comprehensive repair capability is achieved, but the device becomes complex and difficult to handle in unfamiliar situations
Solution Approach 1:
The compressor device integrates multiple functions into a single unified assembly. The compressor motor, air tank, sealant container, valve stem attachment mechanism, and suspension holder are combined into one integrated device that performs sealing, inflation, and self-suspension functions simultaneously.
Solution Approach 2:
The compressor device serves multiple purposes: it seals punctures by injecting sealant, inflates the tire by compressing air into the tire, and automatically positions itself for operation by suspending from the valve. This multi-functionality eliminates the need for separate tools while maintaining comprehensive repair capability.
3Stability of the object's composition
If the compressor is placed on the ground during operation, then stability is achieved, but ground contact interferes with portability and creates issues on uneven or muddy surfaces
Solution Approach 1:
The compressor device autonomously positions itself for operation by utilizing the tire valve as a suspension point. The holder or loop attachment mechanism automatically suspends the compressor from the valve when brought near the tire, eliminating the need for manual placement on the ground and adapting to any surface conditions.
Solution Approach 2:
The operational position of the compressor is changed from horizontal ground contact to vertical suspension from the tire valve. This dimensional shift allows the device to operate stably without ground contact, adapting to uneven, muddy, or inaccessible surfaces while maintaining proper orientation for inflation.
4Adaptability or versatility
If separate hose connections and multiple connection steps are required, then flexible assembly is achieved, but the process becomes time-consuming and prone to misplacement or incorrect assembly
Solution Approach 1:
The mechanical attachment and pneumatic connection functions are merged into a single integrated attachment mechanism. The holder or loop structure simultaneously secures the compressor to the valve assembly and establishes the pneumatic pathway, eliminating the need for separate hose connection steps.
Solution Approach 2:
The compressor is pre-positioned and pre-oriented by the suspension mechanism before operation begins. The holder design ensures the compressor assumes the correct operational alignment automatically upon attachment, eliminating the need for manual adjustment or positioning during the repair process.
