Bicycle Seat Post Integrated CO2 Inflation System

Solution Overview

Problem

Bicycle riders face inconvenience and bulkiness when carrying tire repair kits, especially during rides, as traditional tire pumps are time-consuming, exhausting, and prone to theft or loss.

Innovation Solution

A bicycle seat post with a built-in tire inflator storage system, comprising a cylindrical seat post, post adapter, inflation adapter, and pressurized cartridges, allowing for secure storage and efficient inflation of tires by releasing pressurized gas through a rupture seal mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional tire pump is mounted to the bicycle frame, then the rider can inflate tires during rides, but the pump adds bulk and weight to the bicycle and is prone to theft or loss

Engineering Contradiction:

Improvetire inflation capabilityVSAvoidbulk of repair kit

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent combines the tire pump, storage chamber, and cartridge holder into a single integrated seat post assembly. The pump is mounted within the seat post structure, and the storage chamber is formed inside the seat post, eliminating the need for separate repair kits and reducing overall volume.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The seat post serves multiple functions: it supports the bicycle seat, provides structural support, houses the storage chamber for cartridges, mounts the pump, and acts as the inflation delivery system. This multi-functionality eliminates the need for separate repair equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a traditional tire pump is used, then tires can be inflated, but the process is time consuming and exhausting

Engineering Contradiction:

Improvetire inflation capabilityVSAvoidinflation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent uses disposable pressurized gas cartridges (CO2 or nitrous oxide) as the inflation source. These cartridges provide rapid inflation without requiring manual pumping, significantly reducing both time and physical effort. The cartridges are discarded after use, replacing the need for reusable manual pumps.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If a tire repair kit is carried by the rider, then tire inflation is possible, but it adds bulk and weight

Engineering Contradiction:

Improvetire inflation capabilityVSAvoidweight of repair kit

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The patent combines the tire pump, storage chamber, and cartridge holder into a single integrated seat post assembly. The pump is mounted within the seat post structure, and the storage chamber is formed inside the seat post, eliminating the need for separate repair kits and reducing overall volume.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The seat post serves multiple functions: it supports the bicycle seat, provides structural support, houses the storage chamber for cartridges, mounts the pump, and acts as the inflation delivery system. This multi-functionality eliminates the need for separate repair equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If the pump is mounted to the bicycle frame, then inflation is possible, but it could be stolen or accidentally detached and lost

Engineering Contradiction:

Improvetire inflation capabilityVSAvoidretention of inflation tool

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines the tire pump, storage chamber, and cartridge holder into a single integrated seat post assembly. The pump is mounted within the seat post structure, and the storage chamber is formed inside the seat post, eliminating the need for separate repair kits and reducing overall volume.

Inventive Principle:

AI summary

A bicycle seat support and inflation storage system. A bicycle seat is mounted to a first end of a bicycle seat post. A first end of a post adapter is threaded to a second end of the seat post. A first end of an inflation adapter is threaded to the second end of the post adapter. A pressurized gas cartridge is disposed inside a chamber of the seat post. The system is partially disposed inside a bicycle seat tube during storage. The seat post is removed from the bicycle seat tube and the post adapter is detached from the seat post to release the cartridge. The inflation adapter is detached from the post adapter and attached to a tire tube valve stem. The cartridge is attached to the inflation adapter first end and a rupture seal is broken to release the pressurized gas for inflating the tire tube.
