Bicycle Holder Catching Bar With Strap Closure for Large Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle holders struggle to securely fasten bicycles with large frame sections, such as e-bikes, preventing complete closure and safe retention.
Innovation Solution
A device with a bar equipped with first and second catching means, including a strap or belt connected to a connecting element, allows for complete closure around the bicycle frame, ensuring secure fastening even on bicycles with large frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid arms are used for catching means, then structural strength is improved, but adaptability to different frame sizes deteriorates
Solution Approach 1:
The catching means is divided into two functional parts: rigid arms for structural strength and a flexible strap for adaptability. The rigid arms provide the necessary mechanical strength for blocking the device, while the flexible strap can adapt to different frame sizes and shapes, including very big section frames like e-bikes.
Solution Approach 2:
The strap component allows the catching means to change its physical parameters (length, shape, flexibility) to adapt to different bicycle frame sizes. This enables the same device to securely fasten both standard and large-framed bicycles.
2Ease of manufacture
If fixed-length arms are used, then manufacturing simplicity is improved, but ease of operation deteriorates
Solution Approach 1:
The device separates the fixed rigid arms (easy to manufacture) from the adjustable strap component (easy to operate). The rigid arms can be简单地 manufactured with standard dimensions, while the strap provides the necessary flexibility for easy fastening to various frame sizes.
Solution Approach 2:
The strap introduces dynamic adjustability to the otherwise static rigid arm structure. This allows the catching means to adapt its configuration during operation to accommodate different frame sizes, making fastening easier without complicating the manufacturing of the main structural components.
3Reliability
If rigid structure is used for catching means, then reliability is improved, but adaptability to large frames deteriorates
Solution Approach 1:
The catching means combines rigid arms for reliable structural blocking with a flexible strap that can adapt to large frame sections. The rigid arms ensure reliable fastening through their blocking action, while the strap accommodates various frame sizes including very big section e-bike frames.
Solution Approach 2:
The device uses a composite approach combining rigid materials for the arms and flexible materials for the strap. This composite structure maintains the reliability benefits of rigid components while adding the adaptability of flexible materials to accommodate different frame sizes.
