Articulated Bicycle Frame Clamp for Multi-Bike Carrier Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bike carrier devices often struggle when transporting multiple bicycles, as the front bike can obstruct the mounting process to the yoke and frame of the bike carrier, requiring inadequate adjustment and alignment, which affects the secure fixing of bicycles during vehicle acceleration and braking.
Innovation Solution
A device with a rotatable joint arrangement between the bicycle-side and carrier-side base bodies allows for adjustable orientation and length, enabling the clamping elements to move around obstacles and adjust effectively to the bicycle frame, using a coupling mechanism that converts rotary motion into translational movement for secure clamping and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the device uses a straight tube base body design, then the structure is simple and manufacturing is easy, but the front bike obstructs the mounting process when transporting multiple bicycles
Solution Approach 1:
The base body is designed with articulation points that allow it to change its configuration dynamically. The segments can pivot relative to each other, transforming the structure from a rigid straight tube to a flexible articulated mechanism, enabling the device to adapt to obstacles during mounting operations
Solution Approach 2:
The base body is divided into multiple segments connected by articulation points, allowing each segment to move independently. This segmentation enables the device to navigate around obstacles by adjusting the relative positions of segments, solving the obstruction problem while maintaining manufacturing simplicity
2Adaptability or versatility
If the device allows angle adjustment between base bodies, then versatility and adaptability improve, but device complexity increases
Solution Approach 1:
The joint arrangement incorporates pivoting mechanisms that enable dynamic angle adjustment between the carrier-side and bicycle-side base bodies. This allows the device to adapt to different mounting scenarios and obstacle configurations while using relatively simple mechanical joints rather than complex adjustment systems
Solution Approach 2:
The articulated joint arrangement serves multiple functions: it provides angle adjustment for adaptability, maintains structural integrity for secure mounting, and enables navigation around obstacles. This multi-functionality achieves high versatility without proportionally increasing device complexity
3Device complexity
If the clamping elements are positioned in a fixed straight line, then the structure is simple, but the device cannot accommodate obstacles between the yoke and bicycle frame
Solution Approach 1:
The device incorporates articulation points that allow the clamping elements and base body segments to change their relative positions dynamically. This enables the device to route around obstacles by adjusting the angle and position of segments, transforming the clamping path from a fixed straight line to a flexible articulated configuration
Solution Approach 2:
The mounting path is divided into multiple segments connected by articulation points, allowing each segment to be positioned independently. This segmentation enables the device to navigate around obstacles by adjusting the relative positions of segments while maintaining a relatively simple overall structure
