Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-speed electric vehicles face challenges with rear storage boxes that are difficult to dismantle, prone to rust, and easily damaged, limiting their usability and maintenance.
Innovation Solution
A fixing device with a rotary seat and clamping mechanism that allows easy mounting and dismantling of the storage box through a clamping block and resisting piece interaction, featuring convex ribs and columns for stable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage box is fixed to the vehicle body, then the storage box is stable and secure, but it becomes difficult to dismantle and maintain
Solution Approach 1:
The fixing device employs a rotary seat that can rotate between a locked position (where clamping blocks engage with resisting pieces to secure the storage box) and an unlocked position (where the storage box can be removed). This dynamic mechanism allows the same structure to provide both stability during use and ease of dismantling when needed, resolving the contradiction between fixed stability and dismantling convenience
Solution Approach 2:
The fixing device is divided into separate functional components: a rotary seat, multiple clamping blocks, and resisting pieces. The clamping blocks are distributed around the rotary seat, with each capable of independently engaging with resisting pieces on the vehicle body. This segmentation allows partial engagement or disengagement of clamping mechanisms, facilitating easy dismantling while maintaining stability when fully engaged
2Reliability
If the storage box is permanently mounted, then it is secure, but it is prone to rust and damage due to lack of maintenance access
Solution Approach 1:
The rotary seat mechanism enables dynamic switching between a secured state (where the storage box is firmly attached for reliable operation) and a removable state (where the storage box can be detached for maintenance or cleaning). This resolves the contradiction by allowing the mounting system to provide security when needed while enabling easy access for maintenance when required
Solution Approach 2:
The fixing device allows the storage box to be easily removed and reattached by the user without requiring tools or complex procedures. The rotary seat with its clamping blocks and resisting pieces enables a simple rotate-to-lock or rotate-to-release operation, making maintenance and cleaning accessible to the user themselves, thus improving ease of repair while maintaining mounting security
3Ease of manufacture
If a simple fixing structure is used, then it is easy to manufacture, but it may not provide sufficient stability
Solution Approach 1:
The fixing structure is segmented into multiple identical clamping blocks arranged around the rotary seat, each engaging with its own resisting piece. This modular segmentation allows the use of simple, standardized components that are easy to manufacture, while the collective action of multiple clamping blocks provides sufficient stability. The simplicity of individual components is maintained while achieving overall system stability through repetition and distribution
Solution Approach 2:
The rotary seat merges multiple clamping blocks and resisting pieces into a single integrated rotating mechanism. This combination allows all clamping elements to be engaged or disengaged simultaneously through one rotational motion, simplifying the manufacturing process while ensuring stable attachment when engaged. The merging of components into a unified rotary mechanism maintains structural simplicity while providing reliable stability

AI summary
A fixing device for a storage box of a low-speed electric vehicle; wherein the storage box is configured to be arranged on a rear end of the low-speed electric vehicle. The fixing device includes a rotary seat detachably connected to the storage box, and a mounting portion is concavely formed on the low-speed electric vehicle. The rotary seat is configured to be rotatably assembled in the mounting portion. A mounting surface of the rotary seat is arranged with a convex rib, the convex rib being arranged with a clamping block, and a mounting gap is defined between a part of the clamping block and the convex rib. A resisting piece is convexly formed on the mounting portion, and the clamping block is clamped with or separated from the resisting piece when rotating with the rotary seat.
