Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an additional receiving hole and light-transmitting colored plate are arranged on the housing for sensor installation, then the sensor can receive remote control optical signals, but the visual appearance of the housing is degraded and manufacturing cost increases
Solution Approach 1:
The patent makes the air flowing hole serve dual functions: allowing air circulation for heat dissipation and enabling remote control optical signal reception. By positioning the sensor to face the air flowing hole, the housing structure itself becomes the signal reception pathway, eliminating the need for separate receiving holes or decorative plates while maintaining both thermal management and remote control functionality.
2Ease of operation
If an additional receiving hole and light-transmitting colored plate are arranged on the housing for sensor installation, then the sensor can receive remote control optical signals, but the number of components and manufacturing complexity increase
Solution Approach 1:
The patent merges the air flowing hole (for heat dissipation) with the signal reception function by positioning the sensor to face the air flowing hole. This consolidation eliminates the need for separate receiving holes and decorative plates, reducing component count and simplifying the manufacturing process while achieving both thermal management and remote control signal reception.
3Ease of operation
If a receiving hole is arranged on the housing for sensor installation, then the sensor can receive remote control optical signals, but the housing structure becomes more complex
Solution Approach 1:
The patent makes the air flowing hole serve dual functions: allowing air circulation for heat dissipation and enabling remote control optical signal reception. By positioning the sensor to face the air flowing hole, the housing structure itself becomes the signal reception pathway, eliminating the need for separate receiving holes or decorative plates while maintaining both thermal management and remote control functionality.

AI summary
The invention provides a projector which is characterized by including a housing, a control module and a sensor. The housing is provided with a mounting structure and at least one air flowing hole. The mounting structure is located inside the housing, and the air flowing hole communicates with external environment and an interior of the housing. The control module is disposed inside the housing. The sensor is arranged on the mounting structure and aligns to the air flowing hole. The sensor is electrically connected with the control module, and the sensor receives a remote control optical signal from the external environment to generate an electrical signal and the sensor transmits the electrical signal to the control module. In this way, the manufacturing process of the projector is simplified and the manufacturing cost is reduced.
