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

VSEngineering 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

Engineering Contradiction:
Improveaccessibility of pump and repair accessoriesVSAvoidvolume around bicycle frame
Core Design Contradiction:
Ease of operationVSVolume of moving object

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveavailability for repair proceduresVSAvoidinterference with cyclist line of action
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If traditional external pump storage is used, then accessibility for tire inflation is improved, but portability and compactness are reduced

Engineering Contradiction:
Improveaccessibility for tire inflationVSAvoidportability and compactness
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.
