Solution Overview

Problem

Existing beverage capsule detection systems are complex and costly, and the environmental impact of non-recyclable materials used in traditional capsules is a growing concern, with issues related to reproduction of original capsule colors and codes, and increasing regulatory pressure for biodegradability and compostability.

Innovation Solution

A biodegradable and compostable capsule with a detectable substance embedded in the plastic material, utilizing infrared detection technology to ensure authenticity and simplify the detection process, where the substance is dispersed within the plastic matrix and detectable by a sensor, allowing for easier production and reduced complexity in machine systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If color detection systems with multiple light emitters and sensors are used to detect capsule authenticity, then capsule authentication capability is improved, but device complexity increases

Engineering Contradiction:
Improvecapsule authentication capabilityVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the detection function from complex optical systems and implements it through a simple proximity sensor that detects the presence or absence of a capsule in the dispensing compartment. This reduces device complexity while maintaining authentication capability by using a single sensor instead of multiple light emitters and color sensors.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The proximity sensor serves multiple functions: it detects capsule presence, verifies capsule authenticity, and controls the dispensing process. This multi-functionality eliminates the need for separate detection systems, reducing overall device complexity while maintaining reliable authentication.

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

2Object-affected harmful factors

If biodegradable and compostable materials are used for capsule construction, then environmental compatibility is improved, but detection reliability may worsen

Engineering Contradiction:
Improveenvironmental impactVSAvoiddetection reliability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent uses composite materials consisting of biodegradable plastic material combined with a detectable substance (such as magnetic particles, conductive materials, or RFID tags). This composite structure maintains the environmental benefits of biodegradability while ensuring reliable detection through the embedded detectable substance.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The detectable substance acts as an intermediary between the biodegradable capsule material and the sensor. It enables the sensor to detect the capsule's presence and authenticity without requiring the sensor to directly interact with the biodegradable material itself, thus maintaining both environmental compatibility and detection reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If codes are printed on the capsule film or lateral wall for detection, then capsule identification capability is improved, but manufacturing complexity and production time increase

Engineering Contradiction:
Improvecapsule identification capabilityVSAvoidproduction speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The detectable substance is embedded in the plastic material during the capsule manufacturing process itself, rather than adding codes afterward. This preliminary incorporation of the detection element eliminates post-manufacturing steps, maintaining production speed while ensuring accurate capsule identification through the embedded substance.

Inventive Principle:
Principle #10Preliminary action
