Solution Overview

Problem

Existing methods for disposing of used filters from smokable tobacco products do not effectively document their disposal, leading to environmental pollution and lack of accountability.

Innovation Solution

Equipping the filter unit with a data carrier, such as a magnetically encoded identifier or RFID transponder, to enable automatic identification and verification, allowing documentation of disposal through comparison with a database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a data carrier with identifier is added to the filter unit, then disposal documentation reliability is improved, but device complexity increases

Engineering Contradiction:
Improvedisposal documentation reliabilityVSAvoidfilter unit complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The data carrier is embedded within the filter unit structure, with the identifier integrated into the filter material or mouthpiece. This nesting approach adds the documentation capability while minimizing external additions, thus improving reliability without proportionally increasing overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The data carrier acts as an intermediary element that bridges the filter unit and the disposal documentation system. By separating the identification function into this dedicated component, the core filter unit remains relatively simple while achieving reliable disposal tracking through the intermediary data carrier.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If magnetic encoding or RFID transponder is used for identification, then automatic reading capability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveautomatic reading capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The identification function is extracted as a separate data carrier component that can be manufactured independently and then integrated into the filter unit. This allows specialized magnetic or RFID components to be produced using established processes and assembled into the final product, reducing overall manufacturing complexity while maintaining automatic reading capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs well-established magnetic encoding or RFID parameters that are already standardized in the industry. By using these proven parameters and technologies rather than developing new identification methods, the automatic reading capability is achieved while leveraging existing manufacturing expertise and processes.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the identifier is made visible or accessible from outside, then reading ease is improved, but product appearance is worsened

Engineering Contradiction:
Improvereading easeVSAvoidproduct appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The data carrier is nested within the filter unit structure, with the identifier embedded in the filter material or mouthpiece rather than displayed externally. This allows the identifier to remain accessible to the reading device while maintaining the aesthetic appearance of the filter unit from the user's perspective.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces visual identification mechanisms with magnetic or electromagnetic field-based reading. This substitution allows the identifier to be read through the filter material without requiring visual visibility, thus maintaining product appearance while enabling easy automatic reading through the mouthpiece or filter structure.

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