Innovation Solution
A projecting apparatus comprising light emitting diodes, a light guide plate, and a switching control valve with a reflection layer, where the switching control valve is rotationally connected to an axis, allowing it to switch between on and off positions to control the light source between the light guide plate and the projecting component, simplifying operation and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a computer is used to control the projector, then the projector can be operated and controlled, but the operation becomes complicated and the cost increases
Solution Approach 1:
The patent extracts and removes the computer control system from the projector, eliminating the need for external computer connection. The projector is designed to be self-controlled with built-in timing and projection functions, directly solving the complexity issue by taking out the troublesome computer dependency.
Solution Approach 2:
The projector is designed to be self-sufficient with automatic timing control and self projection capabilities. The device can operate independently without requiring external computer control, making the system serve itself and eliminating the need for complex external control systems.
2Ease of operation
If a computer is used to control the projector, then the projector can be operated, but the cost increases
Solution Approach 1:
The patent removes the computer control component from the system, eliminating the need for expensive computer hardware and interfaces. By extracting this dependency, the manufacturing cost is reduced while maintaining full operational capability through built-in control mechanisms.
Solution Approach 2:
The projector incorporates self-control and automatic timing functions, eliminating the need for expensive external computer control systems. This self-sufficient design reduces manufacturing costs by removing unnecessary external components while maintaining full operational capability.
3Adaptability or versatility
If a switching control valve is added to control light flow, then the light source can be controlled between on and off positions, but the device structure becomes more complex
Solution Approach 1:
The switching control valve serves multiple functions: it controls the light path between on and off positions, directs light to different components, and enables various projection modes. By making this single component multi-functional, the patent achieves versatile light control without proportionally increasing overall system complexity.
Solution Approach 2:
The switching control valve acts as an intermediary component that mediates between the light guide plate and projecting components. It provides a centralized control point for managing light flow to different destinations, simplifying the overall control architecture while enabling versatile light routing functionality.
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
Simplifies the operation process and reduces costs by eliminating the need for a computer to control the projector, while maintaining functionality through the use of a switching control valve and reflection layers to manage light sources effectively.
Implementation Method 1
the switching control valve has a reflection layer mounted on a side thereof to which the light guide plate is connected, and while the switching control valve is switched to the off position, the reflection layer reflects the lights of the light guide plate back to the light guide plate
Data Source
AI summary
The present invention discloses a projecting apparatus. The apparatus includes light emitting diodes, a light guide plate and a projecting component. The light guide plate is mounted between the light emitting diodes and the projecting component. A switching control valve is mounted between the light guide plate and the projecting component. The switching control valve is switched between an on position and an off position between the light guide plate and the projecting component. In the on position, the switching control valve guides lights of the light guide plate to the projecting component as a light source of the projecting component; in the off position, the switching control valve cuts off the lights guided from the light guide plate to the projecting component to further cut off the light source of the light guide plate. The present invention further discloses a projecting equipment.
