Solution Overview

Problem

Humidity from the beverage preparation process can penetrate the resilient support member and affect the circuitry of beverage production machines, leading to incorrect identification of capsules after producing more than 2000 beverages.

Innovation Solution

Incorporating a waterproof material layer between the resilient support member and the discrete conductive parts of the contact means, which are made of materials like silicone or laminates, to prevent humidity from reaching the circuitry and using displaceable probes to read the identification information on the capsule's surface structure, ensuring accurate operation of the machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a resilient support member is used to provide elasticity to the probe and insulate the circuitry, then the probe can return to a non-contact position and provide insulation, but humidity can penetrate the resilient support member after more than 2000 beverages, affecting the circuitry

Engineering Contradiction:
Improvecircuitry insulation reliabilityVSAvoidhumidity penetration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A waterproof material layer is introduced as an intermediary between the resilient support member and the discrete conductive parts. This intermediate layer specifically blocks humidity penetration while allowing the resilient support member to maintain its elasticity and insulation functions. The waterproof layer acts as a mediator that protects the circuitry from humidity without interfering with the probe's mechanical operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The support structure becomes a composite system combining the resilient support member (providing elasticity) with a waterproof material layer (providing humidity barrier). This composite structure integrates two different material functions: the resilient member maintains probe positioning and electrical insulation, while the waterproof layer prevents humidity penetration to protect the circuitry.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If the resilient support member is made of silicone material to provide elasticity and insulation, then the probe can function properly, but humidity can still pass through after extended use

Engineering Contradiction:
Improveprobe elasticity and insulationVSAvoidhumidity resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The support structure is segmented into two distinct functional layers: the resilient support member (silicone) that provides probe elasticity and insulation, and a separate waterproof material layer that provides humidity resistance. This segmentation allows each layer to specialize in one function without compromising the other, solving the contradiction between ease of operation and reliability.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the machine produces more than 2000 beverages, then productivity is improved, but humidity accumulation affects the circuitry leading to wrong identification

Engineering Contradiction:
Improvebeverage production volumeVSAvoidcapsule identification accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The waterproof material layer is installed in advance as a preventive measure before humidity penetration can occur. This preliminary protective action prevents humidity accumulation that would otherwise occur after producing more than 2000 beverages, thereby maintaining capsule identification accuracy throughout the production cycle.

Inventive Principle:
Principle #10Preliminary action
