Dual-Function Barrel Pump Axial Cartridge Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-function barrel pumps with integrated compressed gas dispensers face issues such as mounting interference, safety hazards due to protruding cartridges, lack of storage solutions, and limited working space, which complicate their use on bicycle frames and during cartridge dispensing.
Innovation Solution
A dual-function barrel pump design that allows axial storage of the compressed gas cartridge, features a locking and sealing mechanism for the manual handle, and incorporates a secure method for storing cartridges on both ends of the pump, ensuring safety and ease of use by minimizing parts and maintaining a slim profile for convenient mounting and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the compressed gas cartridge is mounted at an angle off-axis from the barrel, then the cartridge can be dispensed, but mounting interference occurs and the pump cannot be conveniently mounted on a frame
Solution Approach 1:
Instead of mounting the cartridge at an angle off-axis from the barrel, the invention inverts the approach by mounting the cartridge axially at the end of the barrel, with the cartridge axis aligned with the barrel axis. This eliminates the protruding interference problem while maintaining dispensing functionality.
Solution Approach 2:
The invention changes the spatial arrangement from an angled off-axis mounting to an axial end-mounted configuration. This dimensional repositioning allows the cartridge to be stored within the pump's longitudinal axis, eliminating protrusion issues and enabling convenient frame mounting.
2Ease of operation
If the compressed gas cartridge protrudes from the pump, then the cartridge can be accessed, but it creates safety hazards and interference with the user
Solution Approach 1:
The invention applies preliminary anti-action by designing the cartridge mounting orientation so that the cartridge outlet points away from the user's head and body during normal operation. The axial end-mounted configuration with proper orientation prevents the cartridge from becoming a dangerous projectile if rapidly unthreaded, directly counteracting the potential harm before it can occur.
3Ease of operation
If the pump is designed with a slim profile for easy mounting, then mounting convenience is improved, but cartridge storage space is limited
Solution Approach 1:
The invention applies the nesting principle by integrating the cartridge storage function within the pump's existing cylindrical structure. The cartridge is stored axially at the end of the barrel, utilizing the longitudinal space along the pump's axis rather than requiring additional lateral volume. This allows a slim-profile pump to accommodate cartridge storage without compromising mounting convenience.

AI summary
The present invention relates to a versatile manually-actuated barrel style pump also capable of controllably dispensing a compressed gas cartridge. The current invention addresses the shortcomings of the prior art dual function pumps available providing the user with a more versatile dual function barrel pump integrated with a compressed gas cartridge dispenser as well as addresses the deficiencies from the prior art dual function pumps. Compressed gas cartridge storage methods that incorporate with the pump and user ergonomics and increased user safety will also become evident.
