Solution Overview
Problem
Existing protecting structures for vehicles with two or more wheels are not replaceable after serious damage, leading to economic loss and are complex and costly to manufacture.
Innovation Solution
A modular protecting structure that is removably fixable to the chassis using threaded elements, allowing for easy replacement and rapid mounting/dismantling, and can be adapted to various vehicle chassis with the integration of photovoltaic cells for energy supplementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the protecting structure is made as an integral part of the chassis, then the structural strength and stability are improved, but the replaceability and ease of repair deteriorate
Solution Approach 1:
The protecting structure is divided into separate modular components (upper portion, front portion, rear portion) that can be independently replaced. The upper portion bounds the zone from above, the front portion bounds the front, and the rear portion bounds the rear, allowing selective replacement of damaged sections without replacing the entire chassis.
Solution Approach 2:
The protecting structure is extracted from the chassis and made separable through removably fixable connections. Threaded elements and fixing means are used to detach the protecting structure from the chassis, enabling the protecting structure to be removed and replaced independently while the chassis remains intact.
2Stability of the object's composition
If the protecting structure is made as an integral part of the chassis, then the structural stability is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The protecting structure comprises separate portions (upper, front, rear) that can be manufactured independently and then assembled. Each portion can be produced separately using optimized processes for that specific component, reducing overall manufacturing complexity compared to producing a single integrated structure.
Solution Approach 2:
The protecting structure is designed with universal fixing means that can be adapted to different chassis types. The removably fixable connections allow the same protecting structure design to be used across multiple vehicle models, reducing the need for custom manufacturing for each chassis variation.
3Ease of repair
If the protecting structure is made replaceable with removably fixable connections, then the ease of repair is improved, but the structural strength may deteriorate
Solution Approach 1:
Threaded elements and fixing means are pre-installed on the chassis and protecting structure components during manufacturing. These preliminary fixing elements are designed to provide strong structural connections when assembled, ensuring that the removably fixable joints maintain adequate structural strength during normal use while still allowing easy replacement when needed.
