Universal Bicycle Battery Holder Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle accessory mounts are limited in their ability to attach to a wide range of different diameters and shapes of bicycle frames and wheels, as they are typically designed for specific mounting locations and sizes, leading to compatibility issues with modern bicycles.
Innovation Solution
A universal mounting system featuring a V-shaped groove with a notch for engaging curved tubing and interchangeable mounting portions that can be secured to frame tubing and wheels using cable ties, allowing for secure attachment across various diameters and orientations, and a battery holder with a water-tight interior and removable power cables for balanced weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery holder is designed for a specific mounting location and diameter range, then it can be securely mounted at that location, but it cannot be adapted to other mounting locations or different bicycle components
Solution Approach 1:
The battery holder incorporates a universal mounting system with interchangeable mounting portions that can attach to various bicycle components including frame tubing of different diameters, wheel hubs, and handlebars. The mounting portions can be detached and reattached at different locations, allowing the same battery holder to serve multiple mounting purposes across different bicycle components.
Solution Approach 2:
The battery holder is divided into separable components including a removable mounting portion that can be detached from the main body. This segmentation allows the mounting portion to be independently attached or detached from the battery holder body, enabling flexible repositioning and adaptation to different mounting locations without replacing the entire battery holder.
2Manufacturing precision
If a battery holder is designed for a specific diameter range, then it fits that diameter accurately, but it cannot accommodate significantly different diameters
Solution Approach 1:
The mounting portions incorporate adjustable mechanisms including expandable arms and variable positioning features that allow the mounting structure to dynamically adapt to different tubing diameters. The mounting portions can be adjusted to accommodate diameters ranging from approximately 10mm to 60mm, providing both precise fit for each diameter and versatility across the entire range.
Solution Approach 2:
The mounting portions utilize adjustable parameters including variable arm lengths, adjustable positioning slots, and modifiable clamp configurations that can be changed to match different tubing diameters. These parameter adjustments enable the same mounting portion to securely fit tubing of significantly different sizes while maintaining manufacturing precision for each specific application.
3Ease of manufacture
If a battery holder is integrated with the accessory, then it is designed for a specific location, but it cannot power separate devices or be mounted elsewhere
Solution Approach 1:
The battery holder is designed as a separate, standalone unit with removable mounting portions, allowing it to be detached from any integrated accessory and mounted independently on various bicycle components. This segmentation enables the battery holder to power multiple different devices at different locations without being constrained by an integrated design.
Solution Approach 2:
The battery holder is designed as a universal power source that can be mounted on various bicycle components and used to power different accessories including headlamps, tail lamps, and other electrical devices. The removable mounting portions enable the battery holder to be easily repositioned and reconfigured for different applications and locations.
4Stability of the object's composition
If a clamp is designed to fit a limited range of tubing sizes, then it provides a stable mount for that size, but it requires multiple different clamps for different sizes
Solution Approach 1:
A single battery holder design incorporates multiple mounting portions that can attach to tubing of various diameters, eliminating the need for multiple different clamp types. The interchangeable mounting portions provide stable mounting across a wide diameter range while maintaining a simple, unified battery holder structure.
Solution Approach 2:
The mounting system is segmented into interchangeable mounting portions that can be attached to or removed from the battery holder body. This segmentation allows a single battery holder to function as multiple different clamps for different tubing sizes by simply changing the mounting portion, reducing the overall number of components needed.

AI summary
An accessory for attachment to a wheeled vehicle such as a bicycle includes a body portion and a mounting portion. The mounting portion has a V-shaped groove for receiving a wide range of shapes and sizes of frame tubing, wheel hubs, and the like. The groove has first and second portions separated by a notch to engage curved tubing with at least two contacts. A pair of cable ties secures the accessory to the tubing or the hub. A plurality of interchangeable mounting portions can be provided for mounting the accessory to the bicycle in different orientations. When a light is secured to a wheel, the accessory can be a battery holder secured to the hub on an opposite side of the hub from the light to offset weight of the light. The wheel can be balanced with proper radial positioning of the light and the battery holder.
