Bicycle Rack Base Frictional Connection Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle rack assemblies face difficulties in quickly and easily assembling or disassembling the receiving member due to alignment issues and the weight of objects, especially when using sliding rails, which can be cumbersome and labor-intensive.
Innovation Solution
A bicycle rack assembly design featuring a base with engaging recesses and outer portions that form frictional connections, allowing for quick assembly and disassembly by force-fitting the base to the rack, and utilizing a positioning assembly with a movable member and spring for secure attachment and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sliding rails are used to connect the receiving member to the rack, then the receiving member can be removed by sliding off, but alignment becomes difficult and labor-intensive when heavy objects are placed in the receiving member
Solution Approach 1:
The connection interface is segmented into a connection portion with an engaging recess and multiple outer portions, allowing the base to be divided into functional segments that simplify the connection process and reduce alignment complexity
Solution Approach 2:
The positioning assembly acts as an intermediary mechanism between the base and rack, featuring a movable member that can be positioned to facilitate easy alignment and connection without requiring precise manual alignment of the entire base structure
2Adaptability or versatility
If resilient ropes are used to attach objects to the rack, then objects can be attached, but the length of the ropes restricts the size of objects that can be attached
Solution Approach 1:
The attachment system is segmented into a modular base unit with integrated connection features, eliminating the need for separate ropes and allowing objects of various sizes to be attached directly to the rack without length restrictions
Solution Approach 2:
The resilient ropes are extracted from the system and replaced with a direct structural connection through the base and positioning assembly, removing the length constraint entirely while maintaining attachment functionality
3Reliability
If the receiving member is securely attached to the rack, then the connection is stable, but disassembly becomes difficult and time-consuming
Solution Approach 1:
The positioning assembly incorporates a movable member that can dynamically transition between locked and unlocked positions, allowing the connection to be stable during use but easily released when needed, reducing disassembly time while maintaining reliability
Solution Approach 2:
The positioning assembly is designed to facilitate self-service assembly and disassembly, where the movable member can be easily manipulated by the user to quickly release the connection without requiring tools or complex operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and effortless attachment and detachment of the receiving member to the rack, reducing the time and effort required for assembly and disassembly while ensuring secure attachment and easy release.
Implementation Method 1
At least two of the outer portions are in contact with at least two of the lateral portions and friction is formed therebetween so as to attach the base to the rack
Implementation Method 2
a positioning assembly with a movable member and spring for secure attachment and easy release

AI summary
A bicycle rack assembly includes a rack (1) which includes multiple lateral portions (11) that are located adjacent to each other and facing to each other. One of the lateral portions has an engaging recess (12) which includes a narrow area (121) and a wide area (122). A base (2) has a connection portion (22) which is engaged with the engaging recess. The base includes multiple outer portions (21) which are located corresponding to the lateral portions. At least more than two of the outer portions are in contact with at least more than two of the lateral portions and friction is formed therebetween so as to attach the base to the rack. A receiving member (3) is removably connected to the base. The bicycle rack assembly is easily assembled and dis-assembled.
