Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless transceivers are placed on the kettle body and base, then wireless signal transmission is enabled, but the transceivers require precise positioning to ensure accurate and efficient transmission

Engineering Contradiction:
Improvesignal transmission accuracyVSAvoidpositioning requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a reflective mechanism (mediator) between the wireless transceivers and each other to enable signal reflection. This allows the transceivers to be positioned more flexibly on the kettle body and base without requiring precise direct line-of-sight alignment, as the reflected signal path compensates for positional variations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes the spatial dimension by positioning the reflective mechanism at specific angles and locations to create alternative signal paths. By adding this dimensional element (the reflective surface), the system achieves reliable transmission without constraining the transceivers to precise positions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If conventional conductive terminals are used for signal transmission, then power and signal transmission is enabled, but oxidation of output terminals degrades signal quality

Engineering Contradiction:
Improvesignal transmission qualityVSAvoidoxidation of terminals
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical contact-based conductive terminal system with a wireless signal transmission system using infrared transceivers. This substitution eliminates the physical terminals that are susceptible to oxidation, thereby preventing signal degradation caused by terminal corrosion while maintaining reliable communication between the kettle body and base.

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

3Measurement precision

If wireless transceivers require precise positioning, then signal transmission accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvesignal transmission precisionVSAvoidpositioning precision requirement
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The reflective mechanism serves as an intermediary that relaxes the positioning precision requirements for the transceivers. By introducing this intermediate reflective element, the system achieves accurate signal transmission without requiring the transceivers to be positioned with high precision, thus reducing overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An electric kettle includes a kettle body, a base, a heating element and a wireless signal transmission device. The wireless signal transmission device includes a controller circuitry, a first wireless transceiver, a second wireless transceiver, and a light reflection arrangement. The light reflection arrangement includes a first reflective mechanism provided on the kettle body, and a second reflective mechanism provided on the base, wherein when the kettle body is rotatably and detachably coupled with the base through a lower and an upper connector, wherein when one of the first and the second wireless transceiver is activated to generate a wireless signal toward another of the wireless transceiver, the wireless signal is subject to multiple reflections by the first and the second reflective mechanism until the wireless signal reaches the corresponding first and the second wireless transceiver.
