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

VSEngineering 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

Engineering Contradiction:
Improvetransport capacityVSAvoidstability during transport
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvestability during transportVSAvoidtracking state and number of shields
Core Design Contradiction:
Stability of the object's compositionVSLoss of information

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If holding studs and stops are added to position shields, then stability is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)
