Solution Overview

Problem

Existing systems for holding and supplying electrical energy to elongated primary conductors in container systems, particularly for inductive coupling, do not efficiently manage heat insulation and automated storage of refrigerated goods.

Innovation Solution

The system incorporates a housing part with a secondary winding that is inductively coupled to the primary conductor, featuring a thermal barrier with similar or greater specific thermal resistance than the container wall, allowing for inductive electrical supply without a plug connection and enabling automated storage by activating the inductive coupling when containers are stacked.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the secondary part fills the recess in the container wall to enable inductive electrical supply, then electrical energy can be supplied without plug connection, but heat flow may penetrate into the container interior

Engineering Contradiction:
Improveelectrical supply without plug connectionVSAvoidheat flow into container interior
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The secondary part is designed with a thermal barrier having similar or greater specific thermal resistance than the container wall, creating localized thermal insulation at the exact position where electrical supply is needed. This allows the recess to be filled for electrical coupling while maintaining thermal insulation properties at that specific location.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The secondary part comprises a housing part and a thermal barrier, forming a composite structure. The housing part provides mechanical protection and structural support, while the thermal barrier provides thermal insulation. This composite design enables both electrical supply functionality and thermal insulation in a single integrated component.

Inventive Principle:
Principle #40Composite materials

2Productivity

If containers are stacked vertically for automated storage, then storage efficiency is improved, but ensuring reliable inductive coupling for all containers becomes more difficult

Engineering Contradiction:
Improveautomated storage efficiencyVSAvoidinductive coupling reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The holding means with guide elements is designed to universally accommodate multiple containers of the same type in vertical stacks. The guide elements ensure that each container is positioned correctly regardless of its position in the stack, enabling reliable inductive coupling for all containers from a single primary conductor.

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

Solution Approach 2:

The guide elements in the holding means ensure that all containers in the vertical stack are positioned at appropriate intervals along the primary conductor, creating equivalent coupling conditions for each container. This uniform positioning ensures that each container receives adequate electromagnetic energy for reliable operation.

Inventive Principle:
Principle #12Equipotentiality

3Adaptability or versatility

If the primary conductor is laid in a loop for supplying multiple containers, then electrical supply coverage is improved, but the complexity of the system increases

Engineering Contradiction:
Improveelectrical supply coverageVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holding means combines multiple functions into a single structure: it mechanically supports the primary conductor in a loop configuration, provides guide elements for container positioning, and enables inductive coupling for multiple containers. This integration reduces overall system complexity despite the extended electrical supply coverage.

Inventive Principle:
Principle #5Merging (Combining)
