Solution Overview

Problem

Existing container designs for consumer goods, such as cigarette packs, lack effective means to communicate with consumers without adding complexity to manufacturing processes or requiring additional components.

Innovation Solution

A container with a multilayer wrapper containing a conductive layer forming a wireless power transfer receiver coil, allowing an electronic device to be powered externally and communicate with consumers, while minimizing modifications to existing manufacturing processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a marker comprising magnetic resonating means is provided on the outer housing or applied to the outer surface of a foil wrapping material, then the marker becomes detectable by means of an electromagnetic field, but the manufacturing process complexity increases and additional components are required

Engineering Contradiction:
Improveconsumer communication capabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the marker function with the existing wrapper structure by integrating conductive layers directly into the wrapper's multilayer construction. The conductive layers are formed as part of the wrapper manufacturing process itself, merging the communication function with the packaging structure rather than adding separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wrapper structure serves multiple functions: it protects the consumer goods, provides structural integrity, and simultaneously acts as the communication interface through its integrated conductive layers. This multi-functionality eliminates the need for separate marker components while maintaining consumer communication capability.

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

2Duration of action of moving object

If an electronic device is powered by an internal power supply within the container, then the device can operate continuously, but the container size and weight increase

Engineering Contradiction:
Improveelectronic device operation durationVSAvoidcontainer volume
Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The patent extracts the power supply function from the container itself and relocates it to an external power supply unit. The container now only contains the electronic device and necessary circuitry, while power is supplied externally through connections to the conductive layers in the wrapper, reducing container volume and weight.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The conductive layers in the wrapper serve as an intermediary mechanism that transfers power from an external power supply to the electronic device. This intermediary approach allows the device to operate for extended periods without an internal battery, as power can be replenished externally through the wrapper's conductive structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If traditional manufacturing processes are used for forming the container, then production efficiency is maintained, but the means to communicate with consumers is limited to colours, text, graphics, shape, and surface texture

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidconsumer communication capability
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent changes the electrical parameters of the wrapper by incorporating conductive layers with specific resistance values and patterns. These parameter changes enable the wrapper to function as an electronic communication interface while being integrated into existing manufacturing processes that form multilayer wrappers with metallic coatings.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional mechanical/visual communication methods (colours, text, graphics) with an electronic system based on electromagnetic fields. The conductive layers in the wrapper create electrical circuits that can be activated to provide dynamic electronic communication with consumers, substituting static visual elements with programmable electronic displays or indicators.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
