Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless power transmission is performed without visual indicators, then the device structure remains simple, but users cannot spatially recognize the chargeable area
Solution Approach 1:
The patent applies light emitting devices that change color or illuminate to indicate the chargeable area and charging status. Visual indicators provide spatial recognition information to users without complicating the core wireless power transmission structure, resolving the contradiction between structural simplicity and detectability.
2Productivity
If multiple electronic devices are charged simultaneously, then charging capacity increases, but managing and monitoring charging information becomes difficult
Solution Approach 1:
The patent segments charging information display by providing individual visual indicators for each electronic device being charged. This allows users to monitor and manage multiple charging devices simultaneously by distinguishing each device's charging status, capacity, and progress through separate visual cues, thus handling high charging capacity without overwhelming complexity.
3Device complexity
If the chargeable area is fixed, then the wireless power transmitter structure is simple, but adaptability to different charging scenarios is limited
Solution Approach 1:
The patent implements a dynamic chargeable area indication system where the visual indicators can adjust the displayed chargeable area based on different charging scenarios. The system can expand or contract the indicated chargeable area to accommodate different numbers and types of electronic devices, providing versatility without requiring physical structural changes to the transmitter.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily identify and manage charging areas and priorities for multiple devices by visually displaying chargeable areas and related information, enhancing user experience and control over wireless charging.
Implementation Method 1
Electromagnetic induction or resonance types of wireless communication are recently in wide use for smartphones or such electronic devices. If a power transmitting unit (PTU) (e.g., a wireless power transmitter) and a power receiving unit (PRU) (e.g., a smartphone or a wearable electronic device) come in contact or close to each other within a predetermined distance, the battery of the power receiving unit may be charged by electromagnetic induction or electromagnetic resonance between the transmission coil of the power transmitting unit and the reception coil of the power receiving unit.
Implementation Method 2
at least one light emitting device including light emitting circuitry
