Solution Overview

Problem

Existing beverage-making apparatuses face challenges with high energy consumption and risk of dirtying due to constant lighting for optical capsule recognition, and unwanted light emissions.

Innovation Solution

An apparatus with a switchable lighting device that activates only when a capsule is detected in the image capture zone, using a detecting device to control the lighting and image acquisition, minimizing energy use and reducing exposure to potential contamination, while eliminating unnecessary light emissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the lighting device is constantly active for optical capsule recognition, then the capsule recognition is reliable, but the energy consumption increases and the risk of dirtying the image acquisition device increases

Engineering Contradiction:
Improvecapsule recognition reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The lighting device operates periodically rather than continuously, activating only when a capsule is detected in the capture zone and deactivating when no capsule is present. This periodic operation maintains reliable capsule recognition when needed while dramatically reducing overall energy consumption and minimizing exposure to contamination risks.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the detecting device to automatically control the lighting device based on the presence of a capsule, eliminating the need for manual intervention. The lighting device serves itself by activating only when required for capsule recognition, thereby reducing energy waste and contamination risk while maintaining recognition reliability.

Inventive Principle:
Principle #25Self-service

2Reliability

If the lighting device is constantly active, then the capsule recognition is reliable, but unwanted light emissions occur

Engineering Contradiction:
Improvecapsule recognition reliabilityVSAvoidunwanted light emissions
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The lighting device is activated periodically only when a capsule is detected in the capture zone and deactivated when no capsule is present. This eliminates unwanted light emissions during periods when capsule recognition is not needed, while maintaining reliable recognition when a capsule is present.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The harmful unwanted light emissions are extracted or removed from the system by conditionally deactivating the lighting device when not needed. The lighting is separated from continuous operation and only occurs during necessary capsule recognition events, eliminating unnecessary light pollution.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the lighting device is constantly active, then the capsule recognition is reliable, but the wear on components increases

Engineering Contradiction:
Improvecapsule recognition reliabilityVSAvoidcomponent lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The lighting device operates periodically rather than continuously, activating only when a capsule is detected and deactivating when no capsule is present. This reduces the cumulative operating time and wear on the lighting device and image acquisition device, extending their lifespan while maintaining reliable capsule recognition when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The detecting device automatically controls the lighting device to activate only when required, reducing unnecessary wear on components. The system self-regulates to minimize component usage while ensuring reliable operation during capsule recognition events.

Inventive Principle:
Principle #25Self-service
