Innovation Solution
A display device and system incorporating both wired and wireless charging apparatuses, featuring a switch for selecting operating modes, a pad for wireless charging, a terminal for wired charging, and a light emitting unit for status confirmation, allowing users to choose between wireless, wired, or combined charging modes while maintaining the original display functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging apparatus is used separately, then wireless charging function is provided, but it requires separate power supply connection which limits usability
Solution Approach 1:
The patent combines the wireless charging apparatus and wired charging terminal into a single integrated charging device. The wireless charging pad and AC power terminal are merged into one housing, allowing users to charge devices wirelessly or via wired connection without needing separate charging devices or power supply connections.
Solution Approach 2:
The integrated charging device provides multiple charging functions through a single device: wireless charging mode for contactless charging and wired charging mode through the AC power terminal. This multi-functionality allows the device to adapt to different power supply situations and user preferences, enhancing versatility while simplifying operation.
2Ease of operation
If wireless charging technology is adopted, then charging convenience is improved, but device complexity increases due to separate apparatus requirements
Solution Approach 1:
The patent merges the wireless charging apparatus and wired charging terminal into a single integrated unit with unified housing and control. This combination reduces system complexity by eliminating the need for separate wireless charging pads and wired charging devices, while maintaining the charging convenience of wireless technology.
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 convenient and flexible charging options, allowing simultaneous use of devices during charging, with the ability to switch between wireless and wired charging modes, enhancing user experience and device accessibility.
Implementation Method 1
an electromagnetic induction scheme uses an electromagnetic energy coupling generated between several wound coils disclosed in Korean Patent Laid-Open Publication No. 2010-0094197 (laid-open published on Aug. 26, 2010). This scheme is based on Faraday's Law that a magnetic field generated by a coil in which AC or high frequency current flows generates an electromotive force at an output terminal of an adjacent coil.
Implementation Method 2
a light emitting unit connected to the switch and confirming a state of wired charging or wireless charging according to the operating modes
