Display Power Selector for Cable-Free Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in aesthetics and installation due to exposed connection cables when connecting to a separate electronic apparatus for power, and consumers may be reluctant to purchase such setups due to space constraints and visual impact.
Innovation Solution
A display apparatus with a selector that allows selective connection between a wall power source and a power source from a separate electronic apparatus, using switches and converters to manage power supply, enabling automatic switching between AC and DC power sources based on connection states and user control, and a manual switch for user preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display apparatus connects to a separate electronic apparatus for power supply, then the display can receive power, but connection cables become exposed and spoil aesthetics
Solution Approach 1:
The patent combines the power supply function with the display apparatus itself by integrating a power converter and dual connectors (wall socket connector and electronic apparatus connector) into the display. This merging eliminates the need for separate external power adapters and exposed cables, as the display can directly convert power from either source internally.
2Reliability
If a separate electronic apparatus is provided for power supply, then the display can receive power, but it creates space constraints and increases device complexity
Solution Approach 1:
The display apparatus is designed with multi-functionality to receive power from multiple sources through a single device. The integrated power converter can process both wall socket power and electronic apparatus power, making the display universally compatible with different power sources without requiring additional separate power supply equipment.
3Adaptability or versatility
If automatic switching between power sources is implemented, then power connection flexibility is improved, but risk of simultaneous power application increases
Solution Approach 1:
The patent implements a selector that continuously monitors the connection status of both power sources and provides feedback control. When the wall socket connector is detected as connected, the selector automatically switches to use only that power source and disconnects the electronic apparatus power path. Conversely, when the wall socket is disconnected, it switches to use the electronic apparatus power source, preventing simultaneous power application through active monitoring and responsive switching.
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
The solution enhances safety and convenience by allowing users to select power sources easily, preventing simultaneous power application, and improving aesthetics by hiding cables, thus addressing consumer reluctance and installation challenges.
Implementation Method 1
a first converter configured to convert a first power supplied from the first power source
Implementation Method 2
a second converter configured to supply operation power to the display based on power converted by the first converter or a second power supplied from the second power source
