Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless charger is placed on a surface (desktop/countertop) to charge electronic devices, then the charging function is provided, but the wireless charger is visible and occupies surface space

Engineering Contradiction:
Improvecharging convenienceVSAvoidsurface space occupation
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent embeds the wireless charger within the furniture structure (desktop or countertop), nesting the charging device inside the existing furniture. This allows the wireless charger to provide charging functionality while occupying no additional surface space, as it is integrated into the furniture's internal structure

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If wireless interrogation functionality is added to the wireless charger, then device identification capability is improved, but system complexity increases

Engineering Contradiction:
Improvedevice identification capabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the wireless charging functionality and wireless interrogation functionality into a single integrated system. The wireless charger and wireless interrogator share common components such as the transmit coil, controller, and power management circuitry, allowing device identification and charging to be performed simultaneously without proportionally increasing system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

AI summary

A system that incorporates teachings of the subject disclosure may include, for example, wireless chargers combined with wireless interrogators. The wireless chargers can transmit power wirelessly, while also wirelessly interrogating a nearby transponder, such as an RFID tag. The wireless chargers with wireless interrogators can also be programmable to allow user-implemented rules operable in response to an interrogation. Such rules can impose restrictions upon whether wireless charging is allowed to take place. Such rules can also be used to select a power-transmitting protocol that is particularly suited for the electronic device being charged. Other embodiments are disclosed.
