Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control buttons are used for operation, then the display device can be operated from a distance, but multiple operations are required to navigate complex interfaces which is inconvenient and time-consuming
Solution Approach 1:
The patent replaces the mechanical button-pressing system with an optical system. A laser beam is projected onto the display screen to indicate the target position, and a photosensitive sensor detects the beam position. This substitution eliminates the need for multiple remote control operations by enabling direct position selection through beam projection, thereby reducing operation time and improving convenience.
2Ease of operation
If direct contact operation is used, then the operation is simple and direct, but the user must walk to the front of the display panel which is inconvenient
Solution Approach 1:
The patent introduces an intermediary system consisting of a beam emitter and a photosensitive sensor. The beam emitter projects a visible laser beam onto the display screen from a distance, and the photosensitive sensor acts as a mediator to detect the beam position and translate it into control signals. This intermediary system enables simple direct operation from a distance, eliminating the need for users to physically approach the display panel.
3Adaptability or versatility
If a beam projection system is added for remote operation, then remote and intuitive control is enabled, but the device structure becomes more complex
Solution Approach 1:
The patent integrates the beam emitter and photosensitive sensor into the existing display device structure, making the display panel itself serve multiple functions. The display screen not only displays information but also serves as the target surface for beam projection and the sensing area for position detection. This multi-functionality approach adds remote operation capability without significantly increasing overall device complexity.
