Solution Overview

Problem

Existing container carriers with central carrying handles are not suitable for secure hanging on stationary objects, leading to instability and potential container loss, especially when loads are uneven, and become ineffective when wet, causing accidents.

Innovation Solution

The container carrier features recesses on the end walls above the longitudinal wall edges with passage openings, allowing for easy and stable hanging on horizontal elements without translational movement, using radial feed, and a holding section formed by connected end walls for easy transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a central carrying handle is used in the container carrier, then the carrier can be transported by hand, but it cannot be securely hung on stationary objects, leading to instability and potential container loss

Engineering Contradiction:
Improvehand transport capabilityVSAvoidhanging stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention divides the carrying function into two separate components: a central carrying handle for hand transport and recesses with passage openings for hanging on stationary objects. This segmentation allows each component to be optimized for its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container carrier is designed with multiple functions: the central holding section enables hand carrying, while the recesses with passage openings provide hanging capability on stationary objects. This multi-functionality allows the same carrier to serve both transport purposes effectively.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the container carrier is placed on the floor for storage, then it is easily accessible, but it becomes ineffective when the floor is wet and the carton loses load-bearing capacity

Engineering Contradiction:
ImproveaccessibilityVSAvoidload-bearing capacity in wet conditions
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention transitions the storage method from horizontal floor placement to vertical hanging storage by providing recesses that accommodate horizontal stationary elements. This dimensional change elevates the carrier above wet surfaces while maintaining accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the container carrier is designed with recesses on end walls for hanging, then stable fixation is achieved, but the structure becomes more complex

Engineering Contradiction:
Improvehanging fixation stabilityVSAvoidcarrier structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hanging function is localized to specific recesses with passage openings on the end walls, while the rest of the carrier maintains its simple standardized format. This local quality approach adds functionality only where needed without complicating the overall structure.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a cardboard container carrier (1) for storing or transporting several bottles or cups. The cardboard box (1) has a rectangular base, on the bottom surface (3) of which several container compartments (4) are formed, as well as two parallel longitudinal walls (5) forming the outer contour and end walls (6) perpendicular to these, parallel to each other. The end walls (6) each have a circular recess (9) with a through-opening (10) in a region (8) above the edge (7) of the adjacent longitudinal walls (5) for inserting an element (11), for example, a fixed rod or a handrail. For carrying the cardboard box (1), the end walls (6) are connected to each other in an overlapping area (17) at a respective horizontal bend (16) by a plug-in tab connection (18), which thus forms a carrying handle.
