Solution Overview

Problem

Existing stage equipment transport and storage containers are heavy, difficult to manufacture, require excessive storage space, and have walls that bear the weight of the stack, making them unstable and hard to repair.

Innovation Solution

A lightweight, stable stacking container with a frame made of steel profiles and corner reinforcement plates, where the walls, bottom, and lid serve a protective function, allowing for easy removal and replacement, and are designed using water-resistant laminated wood panels, with a simple tool-free mechanism for installing and removing the front and rear walls, and incorporating roller carriers directly connected to the frame for load distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the walls are made thick and heavy to bear the weight of the stack, then the stability is improved, but the weight of the container increases and storage space is reduced

Engineering Contradiction:
Improvestacking stabilityVSAvoidcontainer weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The container is divided into two functional parts: a load-bearing frame structure made of steel profiles that handles stacking forces, and thin non-load-bearing walls made of lightweight material that provide only protective enclosure. This segmentation allows the walls to be lightweight while the frame ensures stacking stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The load-bearing function is extracted from the walls and transferred to a separate frame structure. The walls are taken out of the supporting function and designed solely for protection, enabling them to be made from lightweight materials without compromising stacking stability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the walls are made thick and heavy to bear the weight of the stack, then the stability is improved, but the storage space is reduced

Engineering Contradiction:
Improvestacking stabilityVSAvoidstorage volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The container structure is segmented into a frame that provides structural integrity for stacking and thin walls that provide enclosure. This allows maximum internal storage volume since the walls can be made extremely thin without needing to bear load.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting function is extracted from the walls and assigned to the frame, allowing the walls to be minimized in thickness. This maximizes the internal storage volume while the frame maintains stacking stability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If the walls are permanently fixed to the frame, then the structural integrity is improved, but the ease of repair and replacement is worsened

Engineering Contradiction:
Improvestructural integrityVSAvoidwall replacement ease
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The container is segmented into a permanent load-bearing frame and removable protective walls. The frame maintains structural integrity through rigid connections, while the walls are designed as separate, easily replaceable components that can be removed and reinstalled without tools.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The walls transition from a fixed state to a dynamically removable state. The simple groove-based retention system allows walls to be easily inserted and removed, providing flexibility for repair and replacement while the frame maintains permanent structural integrity.

Inventive Principle:
Principle #15Dynamics

4Strength

If rivets or screws are used to attach the walls to the frame, then the structural integrity is improved, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improveattachment strengthVSAvoidmanufacturing simplicity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The attachment system is segmented into simple geometric features (grooves and edges) rather than complex fasteners. The walls are retained by their own weight in grooves, eliminating the need for rivets, screws, or other complex joining mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The walls themselves serve as their own fastening mechanism through their weight and geometry. The upper edge of the wall is pushed between the legs of U-profiles and locked in position by its own weight, requiring no additional fastening components or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to an apparatus for transporting and/or storing stage equipment, in particular exhibition materials, comprising a box-shaped stacking container which can be moved on running rollers (11) and which has a frame connected to running roller carriers (10) and a base (4), two side walls (5), a front wall (6), a rear wall (7) and a top (8). The frame (1) is formed by profiled rods (2) joined to one another at the corners of the container and running along the edges of the container and is stiffened by corner stiffening plates (3) inserted into the corners of the frame, wherein the profiled rods in each case form mounting frames, into which the base (4), the two side walls (5), the front wall (6), the rear wall (7) and the top (8) of the container are inserted.
