Solution Overview

Problem

Conventional article transportation pallets occupy significant space during storage and transportation, and their large size often requires multiple trucks for delivery, increasing costs.

Innovation Solution

A foldable pallet body with intersecting strip-shaped first and second plate bodies forming quadrilateral regions, held in an expanded state by various holding means, allowing compact storage and efficient transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional fixed-shape pallets are used to transport large articles, then the pallets can load and transport articles during use, but the pallets take up a lot of space in storage areas when not in use

Engineering Contradiction:
Improveloading and transporting articlesVSAvoidspace occupied during storage
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The pallet body is designed to be expandable and foldable, transitioning between an expanded state for loading articles and a folded state for compact storage. The plate bodies are rotatably connected at intersection lines, allowing dynamic transformation of the pallet structure to adapt to different operational requirements.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional fixed-shape pallets are used for delivery, then the pallets can transport goods, but many pallets cannot be loaded on the truck bed or container if they are large, requiring several trucks and increasing transportation cost

Engineering Contradiction:
Improvetransporting goodsVSAvoidtransportation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The pallet body can be folded into a compact state for transportation, allowing more pallets to be loaded onto a single truck bed or container. This dynamic transformation increases the number of pallets that can be transported at once, improving transportation efficiency and reducing the number of trucks required.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If the pallet body is made foldable to reduce storage space, then the pallets become compact, but the pallets must maintain structural strength to withstand heavy articles when expanded

Engineering Contradiction:
Improvestorage spaceVSAvoidload-bearing capacity
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The pallet body is divided into multiple plate bodies (first and second plate bodies) that are arranged in parallel and intersect to form quadrilateral regions. This segmentation creates a lattice structure that provides structural strength while allowing the overall structure to be folded for compact storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pallet body uses a composite structure combining multiple plate bodies made of durable materials such as paper, plywood, plastic, or light metal. This composite construction enhances the load-bearing capacity while maintaining the foldable design for compact storage.

Inventive Principle:
Principle #40Composite materials

AI summary

[Object] To provide an article transportation pallet which does not take up much space during storage or transportation and can normally load and transport articles during use.[Solution Means] The article transportation pallet includes a foldable pallet body 4 having a first surface structure in which a plurality of first plate bodies 2 formed in a strip shape are arranged so as to be parallel to each other in a plane direction and a second surface structure in which a plurality of second plate bodies 3 formed in a strip shape are arranged so as to be parallel to each other in a plane direction, where the plurality of first plate bodies 2 and the plurality of second plate bodies 3 are arranged so that the plurality of second plate bodies 3 intersect with the plurality of first plate bodies 2 to constitute quadrilateral regions S, each surrounded by four wall surfaces composed of two of the first plate bodies and two of the second plate bodies, and the first and second plate bodies 2, 3 are rotatably connected at intersection lines of the first and second plate bodies 2, 3, and when the pallet body 4 is expanded into a use state, a box 15 is accommodated in the quadrilateral region S in order to hold the expanded state.
