Solution Overview

Problem

The rotating shaft system of truck covers in pickup trucks is prone to damage, leading to the risk of the cover detaching from the vehicle body during travel.

Innovation Solution

An anti-detachment hood system comprising a shaft system with hard frames and a rotation center, connected by an anti-detachment structure, which includes features like rotating hooks, clamping parts, and elastic bands to prevent detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rotating shaft system is used to enable the truck cover to open, then the ease of operation is improved, but the reliability deteriorates due to frequent rotation causing damage and loosening

Engineering Contradiction:

Improveease of openingVSAvoidshaft system durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-installing the anti-detachment structure on the shaft system before any damage occurs. This structure includes protective elements that are positioned in advance to prevent detachment, ensuring that when the shaft system undergoes frequent rotation, the cover remains securely attached even if loosening occurs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The anti-detachment structure serves as a protective measure that cushions against the harmful effects of frequent rotation. By having this structure in place beforehand, the patent prevents the worst-case scenario of cover detachment, thereby maintaining reliability while preserving the ease of operation provided by the rotating shaft system

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If the rotating shaft system is used frequently, then the productivity is improved, but the strength deteriorates due to loosening and damage

Engineering Contradiction:

Improvefrequency of useVSAvoidshaft system strength

Core Design Contradiction:

ProductivityVSStrength

Solution Approach 1:

The anti-detachment structure is installed in advance to prevent strength deterioration. This preliminary protective measure ensures that even with frequent use, the shaft system maintains its structural integrity and the cover remains securely attached

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The protective structure acts as a cushion against the cumulative damage from frequent rotation. By having this protection in place beforehand, the patent allows the shaft system to be used frequently without suffering from strength deterioration and loosening

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If the shaft system components are made of hard materials, then the strength is improved, but the ease of manufacture deteriorates

Engineering Contradiction:

Improvematerial strengthVSAvoidmanufacturing difficulty

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent segments the shaft system into distinct components: hard material elements (frames, rotation center) for strength, and the anti-detachment structure for protection. This segmentation allows each component to be manufactured separately with appropriate materials and methods, then assembled together, thereby maintaining strength while improving ease of manufacture

Inventive Principle:

Principle #1Segmentation
