Solution Overview

Problem

Existing display containers and packaging solutions fail to efficiently and safely move goods from the back to the front, leading to visibility issues and increased manual labor costs, as they are often not reusable, lack stability, and can damage goods due to spring-loaded mechanisms.

Innovation Solution

A collapsible and nestable container with a vertically projecting slide plate and actuating element allows for manual displacement of goods from outside the container, enabling easy access without manual re-sorting, while the slide plate can be folded for compact storage and supports goods to prevent falling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If spring-loaded actuators are used to push goods forward, then goods can be moved to the front, but the spring force may be insufficient for heavy goods or too high causing damage to goods and difficulty in filling

Engineering Contradiction:
Improveease of goods movementVSAvoidgoods protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Instead of using spring-loaded actuators that push goods forward, the patent uses a slider that is pulled backward by an elastic element. This inversion of the force direction allows the elastic element to gently guide the slider back to its starting position without exerting excessive force on the goods, thereby protecting them from damage while still enabling effective movement.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The slider acts as an intermediary mechanical element between the user's manual input and the goods. By pulling the slider backward, the user indirectly moves the goods forward without directly contacting them, providing controlled and damage-free operation suitable for various goods weights.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the sliding element is rigidly connected to the actuating element, then the structure is simple, but the container cannot be nested or collapsed

Engineering Contradiction:
Improvestructural simplicityVSAvoidnesting capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The connection between the slider and actuating element is made dynamic rather than rigid. The slider can be pulled backward relative to the actuating element during operation, and the elastic element provides a restoring force. This dynamic connection allows the container to be collapsed or nested while maintaining the functional integrity of the goods-moving mechanism.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If goods are moved to the end of the container, then visibility is improved, but goods may tip over when packed in flexible containers

Engineering Contradiction:
Improvegoods visibilityVSAvoidgoods stability
Core Design Contradiction:
Illumination intensityVSStability of the object's composition

Solution Approach 1:

The slider is designed to extend beyond the container walls when in the forward position, creating a self-supporting structure. This extended slider acts as a built-in support that prevents flexible containers from tipping over, while simultaneously improving goods visibility by moving them to the front. The system serves both functions without requiring additional external supports.

Inventive Principle:
Principle #25Self-service

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 solution reduces manual effort and costs by allowing easy access to all goods, maintaining product stability, and preventing damage, while being reusable and adaptable to various goods sizes and weights.

Implementation Method 1

The sliding element can have a low-friction coating or be made of a low-friction material, facilitating smooth movement

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 2

The sliding element is hinged to the actuating element, in particular by 90°. The sliding element is hinged in the direction of the actuating element to allow the containers to be nested.

Methodology Applied
Scientific EffectHinge mechanism: Hinge
