Assembled Plastic Pallet with Interchangeable Strakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plastic trays are monolithic, making them prone to damage during forklift use, leading to unnecessary replacement and significant waste, especially in large-scale storage operations where only specific sides are damaged, resulting in high replacement costs.
Innovation Solution
An assembled plastic tray design featuring interchangeable strakes of different sizes, where first and second mainboard steel tubes are inserted into corresponding holes, and strakes are mounted on the mainboard through bosses and penetrating slots, with steel tube connection members and blocks for secure fixation, allowing for easy strake replacement and cost savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated injection molding is used to form monolithic trays, then product stability is improved, but waste increases when only side surfaces are damaged
Solution Approach 1:
The tray is divided into multiple separable components: a main body and multiple strakes (side panels). The strakes can be independently removed and replaced when damaged, while the main body remains intact and reusable. This segmentation allows only the damaged portions to be discarded rather than the entire tray, significantly reducing material waste.
2Ease of manufacture
If monolithic tray design is used, then manufacturing simplicity is improved, but repairability deteriorates
Solution Approach 1:
The tray structure is segmented into a main body and detachable strakes connected through joining mechanisms (such as insertion holes, bosses, and fastening elements). This allows the strakes to be independently replaced when damaged, improving repairability while maintaining manufacturing simplicity through standardized connection designs.
Solution Approach 2:
The design enables discarding only the damaged strakes while recovering and reusing the main body and undamaged components. The standardized connection interfaces facilitate quick removal of damaged strakes and attachment of new ones, making the repair process efficient and cost-effective.
3Adaptability or versatility
If interchangeable strakes of different sizes are designed, then adaptability is improved, but device complexity increases
Solution Approach 1:
The main body is designed with universal connection interfaces (such as standardized insertion holes, bosses, and fastening positions) that can accommodate different types and sizes of strakes. This universality allows the same main body to work with multiple strake configurations, improving adaptability without significantly increasing the complexity of the core structure.

AI summary
The disclosure discloses an assembled plastic tray, including a main board and strakes fixed at two sides of the mainboard, wherein, the mainboard includes two rib frames and a plurality of strip-shaped pad feel uniformly distributed between the two rib frames. The steps for assembling the plastic tray includes: firstly, respectively inserting first mainboard steel tubes and second mainboard steel tubes into first mainboard steel tube holes and second mainboard steel tube holes of the rib frames on the mainboard, subsequently, mounting the two strakes on the two side surfaces of the mainboard through a boss and penetrating slots and fixing the boss and the penetrating slots through strake connection blocks, then inserting strake steel tubes into strake steel tube holes on the two strakes, and finally, fixing the strake steel tubes and the first mainboard steel tubes through steel tube connection members and steel blocks. The tray of the disclosure has the advantages of low cost, simple installation, rapid strake change and the like.
