Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate remote controllers are used for each electronic device, then each device can be controlled reliably, but the number of controllers increases causing user inconvenience
Solution Approach 1:
The patent implements a universal remote controller that can control multiple different electronic devices through image projection technology. The controller projects a remote control window onto the target device's display surface, allowing a single controller to perform functions previously requiring multiple dedicated controllers, thus resolving the contradiction between control reliability and user convenience
Solution Approach 2:
The patent introduces an image projection intermediary between the remote controller and the target device. By projecting the remote control window onto the device's display, it creates a new interaction medium that enables universal control while maintaining device-specific control accuracy, solving the contradiction between multi-device compatibility and reliable device control
2Reliability
If multiple remote controllers are used for different devices, then each device receives dedicated control signals, but the complexity of managing multiple controllers increases
Solution Approach 1:
The patent merges the functions of multiple device-specific remote controllers into a single universal controller. By combining control capabilities for TV, air conditioner, audio equipment, and other devices into one unit with image projection technology, it reduces the number of controllers from multiple to one, thereby reducing management complexity while maintaining control accuracy through device-specific reflection patterns
3Ease of operation
If a universal remote controller is designed to control multiple devices, then user convenience improves, but the difficulty of identifying and controlling the correct device increases
Solution Approach 1:
The patent uses different reflection patterns (analogous to visual codes) on different devices that the remote controller's camera can detect and identify. When the controller points at a device, it captures the reflection pattern, identifies the device type, and automatically switches to the appropriate control mode, making device identification intuitive and accurate while maintaining ease of operation
Solution Approach 2:
The patent implements a feedback mechanism where the remote controller projects a test pattern onto the target device, captures the reflected pattern through its camera, and uses this feedback to automatically identify and confirm the target device. This closed-loop feedback system ensures accurate device identification while keeping the operation simple for the user

AI summary
Disclosed herein is a remote controller capable of remotely controlling a plurality of devices. According to one embodiment of the present invention, the remote controller includes a transmitter to transmit a transmitting signal, a receiver to receive a reflective signal from a first reflection pattern, an image projector to project an image outward, an input unit provided with a plurality of buttons, and a controller to perform a control operation to enter a remote control mode for a first device corresponding to the first reflection pattern based on the reflective signal from the first reflection pattern and to perform a control operation to project a remote control window for remote control of the first device outward through the image projector. Thereby, remote control may be performed based on image projection.
