Solution Overview

Problem

Conventional packaging methods for inspection chambers, such as cardboard boxes and transparent plastic film, are inefficient and costly, leading to deformation and increased storage costs due to the need for extensive materials, and do not provide stable stacking during transportation.

Innovation Solution

A stacking aid comprising support structures, such as arcuate and discrete portions, and eyelets, which are integrated or detachably attached to the inspection chamber, allowing for stable stacking and reduced material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If inspection chambers are packed in cardboard boxes, then easy stacking is achieved, but material consumption and cost increase significantly

Engineering Contradiction:
Improvestacking easeVSAvoidcardboard material consumption
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The invention extracts the stacking function from the packaging material (cardboard box) and integrates it directly into the inspection chamber structure through protruding support elements. This eliminates the need for separate packaging materials while maintaining stacking capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The stacking support function is merged with the inspection chamber housing itself. The protruding elements are formed as integral parts of the chamber structure, combining the protective housing function with the stacking aid function in a single component.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If inspection chambers are wrapped in transparent plastic film, then some protection and stacking facilitation is achieved, but deformation occurs due to sunlight exposure

Engineering Contradiction:
Improveprotection from damageVSAvoidchamber shape stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The protective function is extracted from the plastic film packaging and transferred to the structural design of the inspection chamber itself through reinforced walls and integrated support elements, eliminating the need for external packaging that causes deformation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the disposable plastic film packaging with a permanent, reusable structural solution built into the chamber itself, providing ongoing protection without the degradation issues of temporary packaging materials.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If conventional packaging materials are used, then stacking is facilitated, but storage space efficiency decreases due to extensive material usage

Engineering Contradiction:
Improvestacking facilitationVSAvoidstorage space requirement
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The stacking facilitation function is extracted from external packaging materials and integrated into the chamber structure itself, eliminating the volume occupied by packaging materials and improving storage space efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The stacking aid function is merged with the chamber housing, allowing the same structural elements to provide both protection and stacking capability, thereby reducing the overall volume required for storage and transportation.

Inventive Principle:
Principle #5Merging (Combining)

4Object-affected harmful factors

If individual cardboard boxing is used for each inspection chamber, then protection during transport is achieved, but time consumption increases

Engineering Contradiction:
Improvetransport protectionVSAvoidpackaging time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The protective function is extracted from individual packaging processes and integrated into the chamber structure itself, eliminating the time-consuming individual boxing step while maintaining transport protection.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The inspection chamber structure itself provides the protective function that previously required external packaging. The integrated support elements and reinforced structure protect the chamber during transport without requiring separate packaging operations.

Inventive Principle:
Principle #25Self-service

AI summary

A stacking aid for inspection chambers (1) for use in drainage or sewage systems to allow stable stacking of the inspection chambers. The stacking aid comprises at least one support structure (15A, 15B) configured to extend from an exterior surface (19) of a first inspection chamber into an interior of a second inspection chamber and/or adjacent to an exterior surface of a wall defining the interior of the second inspection chamber to thereby reduce movement of the first and second inspection chambers relative to each other in a direction perpendicular to the direction of stacking. An assembly of an inspection chamber stacking aid and an inspection chamber is also provided.
