Solution Overview

Problem

Existing pickup truck covers are prone to structural weaknesses such as deformation, breakage, and water leakage, particularly at the front and rear, due to poor structural strength and inadequate sealing.

Innovation Solution

An ultra-thin embedded hard cover with reinforcing strips is designed, incorporating rotating shafts and edge strips for folding and sealing, with reinforcing strips bonded to the plates to enhance structural strength and provide waterproofing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple plates are combined to form the cover, then the cover can accommodate diverse environments, but the structural strength becomes poor and deformation risk increases

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The cover is divided into multiple detachable plates connected by rotating shafts, allowing the cover to be segmented for flexibility while maintaining overall structural integrity through the connection mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines metal reinforcing strips with plate materials to create a composite structure that leverages the strength of metal strips while maintaining the functional properties of the plates, thereby improving overall structural strength

Inventive Principle:

Principle #40Composite materials

2Weight of moving object

If the cover is made ultra-thin to reduce weight, then weight is reduced, but structural strength and resistance to breakage deteriorate

Engineering Contradiction:

Improvecover weightVSAvoidresistance to breakage

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

Instead of uniformly thickening the entire cover, the patent applies reinforcing strips only at specific locations where strength is needed, maintaining ultra-thin design in non-critical areas while providing localized reinforcement to prevent breakage

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The combination of ultra-thin plates with strategically placed reinforcing strips creates a composite structure that achieves high strength-to-weight ratio, maintaining light weight while providing necessary structural strength

Inventive Principle:

Principle #40Composite materials

3Ease of manufacture

If the cover uses simple plate connections, then manufacturing is simple, but waterproofing performance deteriorates

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidwaterproofing performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces sealing strips as intermediary elements between adjacent plates, which serve as mediators to ensure waterproof connections without complicating the overall manufacturing process, as the sealing strips can be independently attached

Inventive Principle:

Principle #24Intermediary (Mediator)
