Detachable Bicycle Carrier Bracket With Adjustable Struts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle carrying structures face issues such as weight imbalances, aesthetic detractions, limited adjustability, and inflexibility due to their attachment methods and designs, which hinder operation and compatibility with different bicycle sizes and geometries.
Innovation Solution
A detachable carrier assembly featuring a bracket system attachable to the bicycle's head tube, with segments that can be inserted and detached, supporting a container that can be adjusted in orientation and position, eliminating the need for additional struts and allowing for easy removal without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If carrying structures are attached to handlebars through multiple strap or clamping systems, then the carrying structure can be secured to the bicycle, but the carrying structure can move in an axial direction along the handlebars as the rider navigates turns and corners
Solution Approach 1:
The attachment system is divided into multiple discrete components: a bracket assembly that attaches to the handlebar, separate support struts that connect to the front wheel fork, and a carrying structure. This segmentation allows each component to perform its specific function - the bracket provides primary attachment, the struts provide geometric stabilization, and together they create a rigid supported configuration that prevents axial movement while maintaining secure attachment
Solution Approach 2:
The support struts act as intermediary elements between the carrying structure and the bicycle frame. These struts connect the carrying structure to the front wheel fork, creating a triangular geometric relationship that provides structural stability. The intermediaries (struts) transfer and distribute loads, preventing the carrying structure from moving axially along the handlebars while maintaining reliable attachment through the bracket system
2Stability of the object's composition
If struts are added to extend from the carrying structure to the front wheel fork for additional support, then the carrying structure gains stability, but the addition of struts detracts from the aesthetics of the bicycle and adds more weight
Solution Approach 1:
The support struts are designed to be removable and adjustable rather than permanent fixed components. This dynamic design allows the struts to be installed only when additional stability is needed, and removed when not required, thereby reducing the overall weight of the moving object (bicycle with carrying structure) while maintaining the capability to provide stability when necessary
3Reliability
If the carrying structure is semi-permanently attached to the bicycle, then the attachment is secure, but the carrying structure can only be removed with hand tools, providing less flexibility in parking, storing and quickly adjusting
Solution Approach 1:
The bracket assembly incorporates a quick-release mechanism that allows the carrying structure to be rapidly attached and detached from the handlebar without requiring hand tools. This dynamic attachment system maintains secure attachment when engaged while providing the flexibility to quickly remove or adjust the carrying structure when needed, resolving the contradiction between secure attachment and ease of operation
4Device complexity
If the carrying structure is fixed in a single setting, then the attachment is simple, but the carrying structure cannot be adjusted to accommodate bicycles having different sizes, geometries, or handlebar shapes
Solution Approach 1:
The bracket assembly and support strut system are designed with adjustable components that allow the carrying structure to be positioned at multiple locations and orientations. The struts can be adjusted in length and angle, and the bracket can be mounted at different positions on the handlebar, enabling the same basic attachment system to adapt to bicycles of different sizes, geometries, and handlebar shapes while maintaining relatively simple attachment procedures
