Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pickup truck bed covers fail to securely protect cumbersome loads that extend above the side rails, and they often impede the transportation of such loads.

Innovation Solution

A cover system with elongated imperforate panels hinged to bases on the truck's side rails, allowing panels to move between horizontal and vertical positions, ensuring full coverage and securement of loads beyond the side rails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the cover extends only intermediate the side rails of the truck bed, then it provides sufficient protection for goods that cannot tolerate moisture, but it fails to secure valuable goods and impede carrying cumbersome loads that extend above the side rails

Engineering Contradiction:

Improveprotection from moistureVSAvoidability to secure and accommodate cumbersome loads

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The cover is divided into multiple panels (first panel, second panel, third panel, fourth panel) that can be independently positioned and configured. This segmentation allows the cover to adapt to different load configurations, providing both moisture protection for standard loads and extended coverage for cumbersome loads that protrude above the side rails.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cover panels are connected through hinges and latches, allowing them to move between different positions (covering and uncovering states). This dynamic configuration enables the cover to accommodate varying load sizes and shapes, securing cumbersome loads while maintaining protection capabilities.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the cover relies on gravity to seat the cover on tops of the side rails, then it provides simple installation, but it is defeated by cumbersome loads that extend to a higher elevation than the tops of the side rails

Engineering Contradiction:

Improvesimple installation mechanismVSAvoideffectiveness with high loads

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cover panels extend in multiple dimensions beyond the traditional flat cover configuration. The panels can position themselves at different elevations and angles, allowing them to accommodate loads that extend above the side rails while maintaining secure coverage through multi-dimensional positioning rather than relying solely on gravity-based seating.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the cover uses multiple panels that fold back to open, then it provides access to the bed of the truck, but it fails to adequately secure valuable goods that may be transported by truck

Engineering Contradiction:

Improveaccess to truck bedVSAvoidsecurity of valuable goods

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cover system merges multiple functional elements into a unified structure: panels for coverage, hinges for movement, and latches for security. This combination allows the cover to provide both easy access (through panel folding) and reliable security (through the integrated latch mechanism that secures panels in the closed position).

Inventive Principle:

Principle #5Merging (Combining)
