Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the power receiving unit supports multiple wireless power transfer standards, then interoperability with different power transmitting units is improved, but device complexity increases

Engineering Contradiction:

ImproveinteroperabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by detecting the input frequency of the rectifier before establishing power transfer communication. The frequency detector measures the frequency early in the booting process, and the booting trial counter records the number of booting attempts, allowing the selector to determine the appropriate protocol in advance before full power transfer begins, thus avoiding trial-and-error communication attempts

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex mechanical or procedural trial-and-error protocols with an electronic frequency detection and counting system. Instead of attempting multiple protocols sequentially until one works, the system uses the frequency detector and booting trial counter to electronically identify the correct protocol through frequency measurement and booting attempt recording, substituting a sophisticated electronic detection mechanism for simpler but less efficient protocol selection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If protocol selection is made without frequency detection, then device complexity is reduced, but power transfer reliability deteriorates due to failed communication attempts

Engineering Contradiction:

Improvedevice complexityVSAvoidpower transfer reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements feedback by using the booting trial counter to monitor the number of booting attempts and the frequency detector to continuously measure input frequency. This feedback information is fed back to the selector, which uses the recorded booting trial count and detected frequency to intelligently determine the correct protocol, ensuring reliable power transfer communication through informed decision-making based on real-time system state

Inventive Principle:

Principle #23Feedback

AI summary

A wireless power transfer standard selector of a power receiving device and a method therefor are disclosed. A wireless power transfer standard selector according to one embodiment comprises: a frequency sensor for sensing an input frequency of a rectifier; a boot attempt counter for counting and storing the number of bootings in which an output voltage of a power converter is generated and then disappears; and a selection unit for selecting a wireless power transfer standard method by using the input frequency sensed through the frequency sensor and/or the number of bootings counted through the boot attempt counter.
