Solution Overview
Problem
The trolley body of existing mold conveyance trolleys is constructed with large-sized steels, resulting in excessive rigidity and strength, leading to high production costs and increased motor size due to the need for numerous steel members and complex attachment structures.
Innovation Solution
A mold conveyance trolley design featuring a trolley body with first and second side plates oriented vertically, connected by structural frames with parallel linking members and steel pipe members to regulate gaps, allowing for a lightweight and simplified construction that maintains rigidity and supports roller conveyors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large sized type steels are used to construct the trolley body, then rigidity and strength are improved, but weight increases and production cost increases
Solution Approach 1:
The trolley body is segmented into multiple plate members (first plate member, second plate member, third plate member, fourth plate member) connected by linking members, replacing the traditional single-piece large steel construction. This segmentation allows each component to be optimized independently and reduces overall material usage while maintaining structural integrity.
Solution Approach 2:
The invention uses a composite structure combining multiple plate members with linking members to create a lightweight yet rigid trolley body. The combination of these components achieves the required strength without relying on large sized steels, thereby reducing weight while maintaining structural performance.
2Stability of the object's composition
If large sized type steels are used to construct the trolley body, then rigidity is improved, but production cost increases
Solution Approach 1:
The trolley body is divided into multiple plate members (first plate member, second plate member, third plate member, fourth plate member) connected by linking members, replacing the traditional single-piece large steel construction. This segmentation allows each component to be manufactured independently using standard fabrication processes, reducing production cost while maintaining structural rigidity.
Solution Approach 2:
The linking members are designed to be adjustable in length, allowing the structural frame to adapt to different rigidity requirements. This adjustability enables optimization of the structure for minimal weight while achieving the required rigidity, thereby reducing production costs associated with over-engineering.
3Adaptability or versatility
If numerous steel members and complex attachment structures are used, then attachment capability is improved, but device complexity increases
Solution Approach 1:
The linking members serve multiple functions: they connect plate members to form the structural frame, provide adjustability for rigidity optimization, and enable modular assembly of the trolley body. This multi-functionality reduces the need for separate attachment components, thereby simplifying the overall structure while maintaining attachment capability.
Solution Approach 2:
The adjustable length feature of the linking members provides adaptability for different configuration requirements without adding complex attachment mechanisms. This dynamic adjustment capability allows the same structural frame to accommodate various attachment needs while maintaining a simple and unified design.
