Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation and storage of trench shields are challenging due to their size and weight, leading to instability during transport and difficulty in tracking their number and condition post-use.
Innovation Solution
A frame-based storage and transport device with holding studs and stops, along with lifting mechanisms, ensures stable positioning and easy transportation of trench shields, allowing for secure storage and quick inventory of shields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If shields are transported assembled in a dump truck, then transport capacity is improved, but stability during transport deteriorates causing shields to slip and suffer shocks
Solution Approach 1:
The transport system is segmented into a frame structure with multiple crosspieces and longitudinal members, creating distinct positioning zones for each shield. Holding studs and stops are distributed at specific locations along the frame to provide localized stabilization points, preventing shields from moving as a group while maintaining individual positioning control.
Solution Approach 2:
The frame is pre-configured with holding studs, stops, and crosspieces in predetermined positions before shield loading. This preliminary arrangement of restraining elements ensures that when shields are placed on the frame, they are immediately positioned and secured in stable orientations, preventing slippage and shocks during transport without requiring additional active intervention.
2Stability of the object's composition
If shields are transported disassembled, then stability during transport is improved, but tracking the state and number of shields deteriorates
Solution Approach 1:
The frame structure serves multiple functions simultaneously: it provides structural support for disassembled shield components, acts as an organized storage rack that maintains component identification, and functions as a transport platform. The standardized positioning features (crosspieces, holding studs) create consistent placement patterns that make inventory tracking straightforward even when shields are disassembled.
3Stability of the object's composition
If holding studs and stops are added to position shields, then stability is improved, but device complexity increases
Solution Approach 1:
The holding studs and stops are merged into the frame structure itself rather than being separate附加 components. The longitudinal members and crosspieces are integrated to form a unified rigid framework where positioning elements are built-in features. This integration reduces the number of separate parts and simplifies assembly while maintaining effective shield positioning and stabilization.
