Bicycle Seatpost Pump Assembly With Internal Tire Repair Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle pumps and repair accessories create extra volume and aerodynamic drag, compromising cyclist performance and safety due to their external storage and transport, lacking portability and versatility.
Innovation Solution
A pump and accessory set integrated into the bicycle seatpost, featuring a pump with an internal compartment for repair tools and an external capsule, allowing discreet storage within the frame, enhancing portability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pumps and repair accessories are stored externally on the bicycle, then accessibility and availability for use is improved, but volume and aerodynamic drag increase compromising cyclist performance
Solution Approach 1:
The pump and repair accessories are nested within the bicycle seatpost structure. The seatpost contains a hollow interior space that accommodates the pump mechanism, storage compartments for repair kits, and necessary components. This nesting approach allows the pump system to be integrated into the existing bicycle structure without adding external volume, thereby maintaining cyclist performance while ensuring accessibility when needed.
Solution Approach 2:
The seatpost is designed to serve multiple functions: it provides the traditional function of supporting the saddle while simultaneously serving as a storage container for the pump and repair accessories. The seatpost structure includes integrated compartments and mounting mechanisms that allow it to function both as a structural support element and as a portable repair station, eliminating the need for separate external storage.
2Adaptability or versatility
If pumps and repair accessories are stored externally on the bicycle, then availability for repair procedures is improved, but cyclist performance and safety are compromised due to interference with line of action
Solution Approach 1:
The pump system and repair accessories are nested within the seatpost, placing all necessary components inside the bicycle's existing structure. This eliminates external attachments that could interfere with the cyclist's line of action or aerodynamics, while still providing full accessibility to repair tools when needed through integrated access mechanisms.
Solution Approach 2:
The harmful external attachments are extracted and replaced by an internal integration solution. Instead of having pumps and accessories attached to external parts of the bicycle where they interfere with cycling performance, the system extracts these components and relocates them inside the seatpost structure, removing the harmful interference while preserving functionality.
3Ease of operation
If traditional external pump storage is used, then accessibility for tire inflation is improved, but portability and compactness are reduced
Solution Approach 1:
The pump system is merged with the seatpost structure, combining what were previously separate entities (pump and bicycle frame) into a single integrated unit. The pump mechanism, storage compartments, and mounting structures are all combined within the seatpost, creating a compact portable system that maintains full functionality for tire inflation while significantly improving portability and reducing overall device complexity.

AI summary
The present patent relates to a pump and accessory assembly integrated into a bicycle seatpost, which, according to its features, enables the formation of a pump and accessory assembly having its own specific mechanical structure in a format that allows it to be carried inside the seatpost (A) of a bicycle saddle (B), comprising a pump (2) and an external capsule (3) that is fitted to a pumping hose (C) and houses a kit for maintaining and repairing bicycle inner tubes and tyres, including glue, patches, sandpaper, and spatulas. The invention aims to completely optimise manual tyre inflation and repair procedures for bicycles and the like in a wide range of environments, together with storage entirely inside the bicycle frame, allowing for rapid and effective tyre repair.
