Solution Overview

Problem

Existing cover apparatuses for truck cargo boxes face challenges in stable opening and closing operations due to deformation and cannot effectively cover irregularly shaped loads, leading to safety and convenience issues during transportation.

Innovation Solution

A cover apparatus with cross-shaped hinge units, variable members, and rotational driving means that allow for automatic opening and closing, and covers composed of interconnected blocks to adapt to deformed cargo box shapes and irregular loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-plate cover is used, then the structure is simple, but it cannot completely cover irregularly shaped loads and fails when cargo box deformation occurs

Engineering Contradiction:
Improvecover structure simplicityVSAvoidcover operation stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The cover is divided into multiple blocks (first cover block, second cover block, third cover block) connected by hinge assemblies, allowing each segment to independently adapt to deformation and irregular load shapes while maintaining overall cover functionality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge assemblies enable dynamic adjustment of the cover blocks relative to each other, allowing the cover structure to flex and adapt to cargo box deformation and irregular load contours during operation

Inventive Principle:
Principle #15Dynamics

2Device complexity

If traditional hinge structures are used, then the structure is simple, but opening and closing operations become impossible when cargo box deformation occurs

Engineering Contradiction:
Improvehinge structure simplicityVSAvoidcover opening and closing operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The cross-shaped hinge structure adds a rotational degree of freedom in addition to the standard hinge movement, allowing the cover to accommodate deformation through multi-axis movement rather than being constrained to a single plane of motion

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If a single-plate cover is used, then the structure is simple, but transportation safety cannot be secured for irregular loads

Engineering Contradiction:
Improvecover structure simplicityVSAvoidload scattering and falling
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The multi-block cover structure can conform to irregular load shapes more effectively than a single plate, ensuring complete coverage and preventing load scattering while maintaining structural simplicity through modular design

Inventive Principle:
Principle #1Segmentation
