Solution Overview

Problem

Existing pallet storage boxes for utility vehicles have a high dead weight due to complex ribbed constructions, which do not significantly reduce weight while maintaining storage space and security.

Innovation Solution

A receiving device with a flexible cover element and a tensioning device for central clamping, replacing traditional flaps, simplifying construction, reducing weight, and enhancing carrying capacity by forming a smooth surface when closed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a ribbed construction is used to reinforce the floor, then the structural strength is improved, but the device complexity and dead weight increase

Engineering Contradiction:
Improvestructural strengthVSAvoidconstruction complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent replaces the rigid ribbed construction with a flexible tarpaulin cover that is tensioned using a clamping device. This flexible film approach provides the necessary structural reinforcement without the complex ribbed geometry, reducing both device complexity and dead weight while maintaining floor strength.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the physical state and properties of the covering material from rigid (ribbed construction) to flexible (tarpaulin), and uses tensioning to achieve the desired structural properties. This parameter change allows the same reinforcing function to be achieved with a simpler, lighter construction.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If traditional flaps are used for closing access openings, then the closure function is achieved, but the device complexity and weight increase

Engineering Contradiction:
Improveclosure functionVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a flexible tarpaulin cover instead of traditional rigid flaps to close access openings. This flexible film can be tensioned and clamped to provide reliable closure without the complex pivoting mechanisms required by traditional flaps, reducing device complexity and weight.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention replaces the mechanical pivoting system of traditional flaps with a tensioning and clamping system using a tarpaulin. This substitution eliminates the need for hinges, pivots, and associated mounting mechanisms, significantly simplifying the overall mechanical system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If a rigid box construction is used, then the structural stability is improved, but the dead weight increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddead weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent employs a flexible tarpaulin cover tensioned and clamped to the frame structure, replacing the need for heavy rigid box construction. The tensioned flexible film provides sufficient structural stability for pallet storage while dramatically reducing the dead weight compared to traditional rigid boxes.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention transitions from a static rigid structure to a dynamic flexible system that can be tensioned and adjusted. The tarpaulin cover can be dynamically tensioned using the clamping device to achieve the required structural stability, allowing the same function with much lower weight.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If access openings are made larger for easier loading, then the ease of operation is improved, but the security and closure reliability worsen

Engineering Contradiction:
Improveloading easeVSAvoidclosure security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses a flexible tarpaulin cover that can be tensioned and clamped securely over large access openings. This flexible film maintains closure security and reliability even for large openings that would be difficult to close with traditional rigid flaps, allowing easy loading while maintaining security.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the closure mechanism from rigid mechanical flaps to a flexible tensioned system. This parameter change allows large access openings to be securely closed using tension and friction from the clamping device, maintaining closure reliability while facilitating easier loading operations.

Inventive Principle:
Principle #35Parameter changes

AI summary

The case has a loading space (10) including side and base boundaries (11, 13) and a roof boundary. The side boundary includes an access opening (14) for the loading space. A flexible cover unit opens and closes the access opening. A clamping device (16) centrally clamps the cover unit in a closing position and includes a winding shaft that is connected with the cover unit. A free edge of the cover unit includes a piping that is engages with a piping groove of the shaft. An axial stopper is arranged on the rotary drive for axially fixing the shaft.
