Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If rigid protective shells are used, then protection against bad weather is improved, but weight and cost increase
Solution Approach 1:
The patent replaces rigid protective shells with a flexible canvas wall that provides weather protection while being significantly lighter. The flexible wall can be made of waterproof or water-resistant materials that protect against rain and wind without the weight penalty of rigid structures.
Solution Approach 2:
The invention uses composite construction combining a flexible canvas wall with a lightweight frame structure. The frame provides structural support while the canvas provides weather protection, creating a composite system that achieves protection without the weight of solid rigid shells.
2Ease of operation
If pre-installed fastening systems are used, then installation is simplified, but device complexity and cost increase
Solution Approach 1:
The patent enables users to install the protective device themselves using simple attachment mechanisms that require no specialized tools or pre-installed components on the bicycle. The device includes its own attachment means that can be directly fixed to the bicycle frame.
Solution Approach 2:
The protective device is divided into separate modular components (frame, canvas wall, attachment means) that can be independently assembled and installed. This segmentation allows for simple step-by-step installation without requiring complex pre-assembled fastening systems.
3Reliability
If heavy protective structures are used, then durability is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The flexible canvas wall provides sufficient durability for weather protection while being lightweight and easily foldable. The flexibility of the material allows it to withstand environmental conditions without requiring heavy rigid construction.
Solution Approach 2:
The frame structure is designed to be elastically deformable, allowing the entire device to be folded compactly for transport and then expanded when needed. This dynamic structure maintains durability during use while enabling easy portability when folded.
