Bicycle Carrier Quick-Release Locking for Stable Frame Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle carriers experience unstable relative movement between the main frame and mounting rod during vehicle travel, leading to potential bicycle falls due to easy disengagement of the positioning mechanism.
Innovation Solution
A carrier design featuring a mounting rod connected to a vehicle, with a frame body including a connecting seat, stand rod, and lateral rods, utilizing a first quick-release mechanism with an elastic abutting portion to securely position the connecting seat and prevent unexpected rotation, ensuring stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main frame and mounting rod are rotatably connected to allow door opening without dismantling, then the ease of operation is improved, but the relative movement becomes unstable during travel
Solution Approach 1:
The rotatable connecting seat enables the carrier to transition between a compact first position (for stable travel) and an extended second position (for door opening). This dynamic reconfiguration allows the system to optimize for either stability or operational convenience depending on the operational phase, resolving the contradiction between these two requirements.
Solution Approach 2:
The elastic abutting portion provides preliminary positioning action by blocking rotation to the second position during travel. This pre-established constraint prevents unstable relative movement before it can occur, while still allowing intentional rotation to the first position for door opening 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
The carrier maintains stable and safe positioning of the bicycle during vehicle movement, preventing falls and allowing easy door opening by using a combination of elastic and rotatable components to secure the connecting seat in place.
Implementation Method 1
a first quick-release mechanism, including a first elastic abutting portion, the first elastic abutting portion being disposed on one of the mounting rod and the connecting seat, the first elastic abutting portion being blockably abuttable against the other of the mounting rod and the connecting seat
