Bicycle Lock Pump Integrating Piston Cylinder and Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle accessories lack a combination pump and lock that incorporates a flexible cable for securing bicycles, with no simple and reliable way to use one end for both tire inflation and locking, and lack a flexible cable lock with a piston-cylinder pump and lock bolt or shackle.
Innovation Solution
A combination lock and pump featuring a flexible, break-resistant cable with a male end that includes both a pump piston-cylinder and a lock bolt or shackle, and a female end with receiving apertures for tire valve stems and a lock bolt, connected by an air inflation tube running parallel to the cable, allowing for dual functionality as a lock and pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate accessories (lock, pump, tools) are carried on a bicycle, then security and tire inflation functions are provided, but space is consumed and weight is added
Solution Approach 1:
The patent combines a cable lock and a tire pump into a single integrated accessory. The cable lock includes a flexible cable with a lock body at one end and a lock bolt at the other end, while the pump is integrated into the lock body structure. This merging of previously separate accessories (lock and pump) into one unified device reduces the number of separate items needed, thereby saving storage space on the bicycle while maintaining both security and tire inflation functions.
Solution Approach 2:
The cable lock structure is designed to serve multiple functions: it provides security through the locking mechanism and simultaneously serves as a tire pump. The lock body houses both the locking components and the pump mechanism, allowing the single accessory to perform both protective and maintenance functions. This multi-functionality eliminates the need to carry separate lock and pump accessories.

3Ease of operation
If accessories are stored with the bicycle and left unattended, then convenience is provided, but the accessories may be stolen
Solution Approach 1:
The patent combines a cable lock and a tire pump into a single integrated accessory. The cable lock includes a flexible cable with a lock body at one end and a lock bolt at the other end, while the pump is integrated into the lock body structure. This merging of previously separate accessories (lock and pump) into one unified device reduces the number of separate items needed, thereby saving storage space on the bicycle while maintaining both security and tire inflation functions.
4Area of stationary object
If a single accessory integrates both lock and pump functions, then space and weight are reduced, but structural complexity increases
Solution Approach 1:
The patent integrates the pump mechanism within the lock body structure. The pump is nested inside the lock body, with the piston and cylinder components arranged within the available internal space of the lock assembly. This nesting arrangement allows the pump to be housed within the existing lock structure without requiring additional external space, thereby maintaining a compact form factor while achieving multi-functionality.
Solution Approach 2:
The cable lock is divided into distinct functional segments: the flexible cable portion, the lock body, the lock bolt, and the integrated pump mechanism. Each segment performs a specific function and can be independently analyzed or manufactured. The lock body serves as the central hub that houses both the locking mechanism and the pump, while the cable and bolt provide the security function. This segmentation allows for modular construction and assembly.

AI summary
A combination lock and pump for use with a bicycle. The combination lock and pump has a flexible cable including an inflation tube running parallel with a metal rope or chain. The flexible cable has a male end preferably including a lock bolt or shackle and a piston-cylinder pump. The flexible cable also has a female end preferably including a lock cylinder with a key hole and one or more apertures to receive either a bicycle tire's valve stem or the male end's lock bolt or shackle. When used as a lock, the combination secures the bicycle from theft by looping the flexible cable around the bicycle and locking together its male and female ends. When used as a pump, the combination's female end attaches to the bicycle tire's valve stem and inflates the tire by actuating the pump of the male end.
