Solution Overview

Problem

Existing packaging inserts for transport containers, particularly folding boxes, lack flexibility to accommodate goods of different sizes and shapes, leading to the need for multiple inserts and increased risk of damage during transport.

Innovation Solution

A packaging insert with a single hollow floor that can be wrapped with a film web, featuring a resilient membrane and adjustable wing supports to ensure secure positioning and protection of goods, allowing for universal use with various sizes and shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a packaging insert with fixed cavity dimensions is used, then goods of specific sizes can be securely positioned, but flexibility to accommodate goods of different sizes and shapes is reduced

Engineering Contradiction:

Improveflexibility to accommodate different goodsVSAvoidneed for multiple packaging inserts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging insert employs movable side walls that can be adjusted to different positions, transforming a static structure into a dynamic one. This allows the same packaging insert to adapt to goods of varying sizes and shapes by reconfiguring the internal cavity dimensions, thereby providing versatility without requiring multiple different inserts

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The packaging insert is designed with adjustable side walls and reconfigurable structures that enable a single insert to serve multiple functions for different product types and sizes. This universal design eliminates the need for maintaining multiple specialized inserts, reducing complexity while improving adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If goods are placed on a membrane without additional securing, then placement is simple, but goods may displace during transport increasing damage risk

Engineering Contradiction:

Improveease of goods placementVSAvoidprotection against goods displacement

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The packaging insert utilizes a membrane as a flexible base for placing goods, maintaining simplicity of operation. The membrane's flexibility allows easy goods placement while the surrounding adjustable side walls and structural elements provide securing mechanisms that prevent displacement during transport, balancing ease of operation with reliability

Inventive Principle:

Principle #30Flexible shells and thin films

3Device complexity

If a single hollow floor design is used, then wrapping with film web is simplified, but shock absorption capability may be reduced compared to multi-level structures

Engineering Contradiction:

Improvesimplicity of wrapping structureVSAvoidimpact energy on goods

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The single hollow floor is covered with a film web that provides shock absorption and cushioning capabilities. The flexible film material absorbs impact energy while maintaining the structural simplicity of a single-level design, avoiding the complexity of multi-level hollow floors while still protecting goods from damage

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The combination of the rigid hollow floor structure with the flexible film web creates a composite system that benefits from both materials. The film web adds shock absorption properties to the simple single-level structure, mitigating impact forces on goods without requiring complex multi-level constructions

Inventive Principle:

Principle #40Composite materials

AI summary

The invention relates to a packaging insert (100) for the shock-absorbing arrangement of goods (W) within a transport container, in particular a folding box. The packaging insert (100) comprises a blank (1) that can be folded to form a hollow base (101), which has wing walls (7-9) that can be folded along fold lines (F1-F3), as well as a frame (3) and a wall section (4) connecting the frame (3) to a base plate (2), at which the frame (3) and the base plate (2) can be folded along fold lines (F4, F5). A membrane (6) for receiving the goods that can be placed on it is attached to the frame (3), and this membrane at least partially covers an opening (5) defined by the frame (3).According to the invention, the base plate (2) has a free edge (2a) opposite the wall section (4) with the frame (3) arranged thereon, in order to fix the goods (W) placed on the membrane (6) between the membrane (6) and a section of the film (201) by wrapping the intended folded blank (1) with a separate film strip (201) transversely to this free edge (2a).
