Elastic Band Tire Pump Coupling for Valve Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure increase devices require cumbersome coupling mechanisms and additional accessories, making them inefficient and cumbersome to use across different valve types, especially requiring manual effort and complex equipment.
Innovation Solution
A device with an elastic band that positions around the tire to secure a pump nipple to the valve, providing an airtight seal without manual effort, suitable for all valve types, including those with reducing valves, and featuring a recess with a tapering inner wall and compressible material for secure fitting, allowing easy manufacturing and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber compression mechanism or clamp is used to couple the pump nipple to the valve, then an airtight seal can be achieved, but the device complexity and manual effort required increase significantly
Solution Approach 1:
The elastic band automatically secures the pump nipple to the valve without requiring manual operation of clamps or compression mechanisms. The band self-adjusts to maintain an airtight seal through its elastic properties, eliminating the need for complex manually-operated coupling devices.
Solution Approach 2:
The patent replaces complex mechanical coupling systems (clamps, lever-operated compression mechanisms) with a simple elastic band that uses elastic force instead of mechanical fastening. This substitution dramatically simplifies the device while maintaining sealing reliability.
2Reliability
If a clamp or special coupling device is used for Dunlop- or Blitz-type valves, then secure coupling is achieved, but the ease of operation and portability are reduced
Solution Approach 1:
The elastic band automatically secures the pump nipple to various valve types without requiring the user to manually operate clamps or adjust coupling mechanisms. The band self-adjusts to accommodate different valve types (Presta, Schrader, Dunlop, Blitz) while maintaining secure coupling.
Solution Approach 2:
The elastic band design provides universal compatibility with multiple valve types without requiring different coupling mechanisms. A single device configuration can secure various valve types, eliminating the need for type-specific clamps or adapters.
3Reliability
If complex coupling mechanisms are used to secure the pump nipple, then reliable coupling is achieved, but the weight and manufacturing cost increase
Solution Approach 1:
The elastic band provides reliable coupling through its inherent elastic properties without requiring additional heavy components. The band self-adjusts to maintain secure attachment, eliminating the need for weighty mechanical fastening systems while preserving coupling reliability.
Solution Approach 2:
The elastic band is a simple, inexpensive component that can be easily replaced if needed. This approach uses a low-cost, simple component instead of expensive, complex mechanical coupling systems, reducing both weight and manufacturing cost while maintaining functional reliability.
