Solution Overview

Problem

Job sites often lack working surfaces, necessitating the use of sawhorses or work tables in pickup trucks, which occupy valuable space and can damage the truck's finish when used as tables.

Innovation Solution

A multifunction tonneau cover for pickup trucks that can be easily converted between a load bed cover and a work table, featuring leg receivers, storage pockets, a cover section, and reinforcement section, with gas struts and a hinge assembly for efficient conversion, protecting the finish by flipping the surface when used as a table.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sawhorses or work tables are loaded into the load bed to provide working surfaces, then working surfaces are available at job sites, but valuable load bed space is occupied and cannot be used for other cargo

Engineering Contradiction:
Improveavailability of working surfaceVSAvoidload bed space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The tonneau cover is designed to serve multiple functions: it acts as a load bed cover during transport and transforms into a work table at job sites. This multi-functionality eliminates the need to carry separate work tables, as the cover itself provides both protection and working surface capabilities.

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

Solution Approach 2:

The tonneau cover incorporates collapsible legs that can be extended to transform the flat cover into a elevated work table, and retracted to return to its original cover function. This dynamic transformation allows the same object to adapt between different uses without occupying additional space.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If sawhorses or work tables are used as work surfaces, then working surfaces are available, but the truck's finish can be damaged

Engineering Contradiction:
Improveavailability of working surfaceVSAvoiddamage to truck finish
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The tonneau cover transforms from a flat cover to an elevated work table by extending collapsible legs, creating a dynamic structure that lifts the working surface away from the truck bed. This elevation prevents direct contact between the work surface and the truck's finish, eliminating the risk of damage.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the tonneau cover is converted between load bed cover and work table functions, then versatility is improved, but conversion time and complexity increase

Engineering Contradiction:
Improvefunction conversion capabilityVSAvoidconversion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The tonneau cover is divided into modular components including the cover body and separate collapsible leg assemblies. These segmented parts can be independently manipulated, allowing the legs to be quickly extended or retracted without affecting the cover structure, thereby simplifying and speeding up the conversion process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collapsible legs are designed to nest within each other when retracted, similar to a nested doll structure. This nesting mechanism allows the legs to compact into a small space within the tonneau cover, enabling quick deployment and retraction without requiring complex assembly or disassembly procedures.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The tonneau cover effectively serves as a work table without occupying load bed space, freeing it for other cargo and protecting the truck's finish, while allowing quick and efficient conversion between functions.

Methodology Applied
Scientific EffectGas spring: Elasticity

Implementation Method 2

Each leg of the plurality of legs may include a tapered end that friction fits in one leg receiver of the plurality of leg receivers

Methodology Applied
Scientific EffectFriction fit: Friction
