Ground-Anchored Bicycle Pump with Segmented Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle pumps are lightweight, prone to wear and tear, and difficult to disassemble, making them less durable and cumbersome to use for maintaining tire pressure, especially in public settings exposed to the elements.
Innovation Solution
A robust bicycle pump design featuring a ground-anchored body with a detachable top portion, a handle assembly, and a hose system with a pressure gauge, including annular grooves for secure plate connections and 'push to connect' fittings for easy assembly and maintenance, allowing for secure anchoring and efficient air displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional bicycle pumps are made lightweight, then portability is improved, but durability and robustness deteriorate
Solution Approach 1:
The pump is divided into multiple separable components including a pump body, handle assembly, hose with nozzle, and base. This segmentation allows each component to be optimized independently - the body can use robust materials for durability while individual parts can be replaced if damaged, effectively resolving the contradiction between lightweight design and durability.
2Strength
If pump parts are integrally formed as a single piece, then structural strength is improved, but ease of disassembly and maintenance deteriorates
Solution Approach 1:
The pump employs multiple connection mechanisms that allow the structure to be strong when assembled but easily disassembled for maintenance. The handle assembly connects to the body via a pin or bayonet connection, the hose connects via push-to-connect fittings, and the base anchors via removable feet. This resolves the contradiction by providing integral strength during operation while enabling easy disassembly for repair.
Solution Approach 2:
The pump transitions from a static integrated structure to a dynamic modular structure where components can be easily assembled and disassembled. The quick-connect fittings and removable connections allow the pump to adapt between a unified strong structure during use and a separable structure for maintenance, resolving the contradiction between structural strength and ease of repair.
3Ease of operation
If public pumps are mounted outdoors, then accessibility is improved, but exposure to elements causes wear and tear
Solution Approach 1:
The pump base includes pre-installed protective features such as rubber feet for ground protection, a corrosion-resistant coating on the metal body, and a weather-resistant hose. These protective measures are built in beforehand to cushion against the harmful effects of outdoor exposure, resolving the contradiction between accessibility and environmental durability.
Solution Approach 2:
The pump utilizes composite construction with a metal body (for strength), rubber or plastic components (for weather resistance), and coated surfaces (for corrosion protection). This combination of materials with complementary properties allows the pump to withstand outdoor elements while remaining accessible and functional, resolving the contradiction between accessibility and environmental exposure.
4Ease of repair
If pump components are made replaceable, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The pump is designed with clearly segmented components that connect through standardized interfaces. The handle assembly, hose, nozzle, and base are separate replaceable parts with simple connection mechanisms. This segmentation enables easy replacement of individual components without requiring complex disassembly procedures, resolving the contradiction between ease of repair and device complexity.

The pump provides a durable, easy-to-use solution for maintaining tire pressure with robust materials and user-friendly features like an oil-filled pressure gauge and magnetic nozzle head, allowing for easy replacement of components and improved longevity.
Implementation Method 1
When the piston rod is moved downward within the tube, air is displaced from the tube and through the air line to the hose such that the head dispenses air

AI summary
A pump for inflating tires with air is provided. The pump includes a body having a base and a top portion and a cutout configured to receive a tire of a bicycle. The base is configured to be anchored to the ground. The pump includes a handle assembly including a piston rod and a handle bar. The pump includes a tube positioned in the body and secured to at least one plate in the body. The tube slidably receives the piston rod and is connected to an air line. The pump includes a hose connected to the air line and extending from the body. The hose has a head configured to engage a nozzle of the tire. When the piston rod is moved downward within the tube, air is displaced from the tube and through the air line to the hose such that the head dispenses air.
