Solution Overview

Problem

Existing carrying devices for kegs, such as beer containers, face issues with stackability and material efficiency, as they often require more material and have insecure fastening mechanisms, leading to difficulties in stacking and reusability.

Innovation Solution

A combination of a keg and a carrying device featuring an annular bead on the keg's top with a ring-shaped base and clips for secure attachment, allowing the handle to pivot within the plane of the insert ring, enabling easy stacking and one-handed carrying, while being made from cost-effective thermoplastic materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a carrying device with handle is attached to the top of a keg, then the keg can be carried comfortably with one hand, but the stackability of the kegs deteriorates due to increased height and interference with stacking interface

Engineering Contradiction:
Improveone-handed carryingVSAvoidstackability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The carrying handle is designed to be movable relative to the ring-shaped base, allowing it to pivot between a horizontal transport position and a vertical stacking position. This dynamic configuration enables the handle to adapt to different operational states: during transport it provides ergonomic handling, during stacking it retracts to maintain proper keg alignment and interface contact

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The carrying device is designed with a ring-shaped base that fits within the annular bead structure of the keg top, and the handle pivots within the plane of this ring. When stacked, the carrying device of one keg nests within the structural envelope of the keg above, with the handle completely accommodated within the circumference of the flanged edge, maintaining the original stacking interface

Inventive Principle:
Principle #7Nested doll (Nesting)

2Device complexity

If simple carrying devices with articulated handles are used, then the structure is simple and space-saving, but the fastening mechanism becomes insecure and attachment reliability deteriorates

Engineering Contradiction:
Improvestructure simplicityVSAvoidfastening security
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The fastening function is merged with the ring-shaped base structure itself. The base incorporates multiple attachment points integrated into its circumferential structure, eliminating the need for separate fastening components. This unified design maintains structural simplicity while providing multiple distributed attachment points that collectively enhance fastening security and load distribution

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The attachment mechanism is segmented into multiple discrete attachment points distributed around the circumference of the ring-shaped base. Each attachment point provides independent fastening capability, and the collective effect of multiple points creates a secure, redundant fastening system that distributes mechanical loads evenly around the keg opening

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If conventional carrying handles are attached to kegs, then carrying functionality is provided, but material consumption increases and manufacturing cost rises

Engineering Contradiction:
Improvecarrying functionalityVSAvoidmaterial consumption
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The carrying device utilizes a thin-walled ring-shaped base structure that provides sufficient mechanical strength for attachment and handle support while minimizing material volume. The structure employs optimized wall thickness distribution and geometric reinforcement to achieve high strength-to-weight ratio, reducing material consumption while maintaining carrying functionality

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The ring-shaped base serves multiple functions simultaneously: it provides the structural framework for attachment to the keg, acts as the mounting platform for the carrying handle, defines the geometric envelope for handle movement, and provides the interface for fastening mechanisms. This multi-functionality eliminates the need for separate structural components, reducing overall material consumption

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

Applied Scientific Principles

AI summary

The handling cradle (1) has an annular base at which a carrying handle (2) is articulated secured and three attaching units are arranged for fastening the cradle. The annular base is designed with a depositor ring (3) inlaid into a flanged rim (22) at a top face (21) of a firkin (20). The hinges (4) are arranged at opposed sides of the ring and are connected with ends of the handle. The hinges are arranged for enabling the pivoting of the handle in a plane of the ring such that the handle is received completely in the plane of the ring in a non-use arrangement.
