Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the PIR sensor is integrated into the LED lamp bulb to provide inductive control functions, then the control functionality is improved, but the adaptability and ease of operation deteriorate because the sensor cannot be removed and the bulb cannot function as a common LED lamp
Solution Approach 1:
The PIR sensor is designed as a separable module that can be independently removed from the LED lamp bulb. The sensor housing includes a threaded portion that engages with the lamp base, allowing the sensor to be detached and the bulb to function as a standard LED lamp without the inductive control component.
Solution Approach 2:
The system transitions from a fixed integrated design to a dynamic configurable design where the PIR sensor can be installed or removed based on user needs. The threaded connection mechanism enables the sensor to be dynamically attached or detached, providing flexibility in functionality.
2Adaptability or versatility
If the PIR sensor is made removable to improve adaptability and ease of operation, then the versatility is improved, but the device complexity increases due to the need for additional mounting and connection structures
Solution Approach 1:
The lamp base is designed with a threaded connection structure that serves dual purposes: it functions as the standard electrical connection for the LED bulb and simultaneously as the mounting mechanism for the PIR sensor. This universal interface simplifies the overall structure by combining multiple functions into a single component.

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 design allows for increased control functions and expanded applications by enabling the lamp bulb to be used as a common LED lamp bulb, with adjustable timing and environmental sensing, improving service life and radiation quality through efficient heat dissipation and remote control capabilities.
Implementation Method 1
the IR sensing source of PIR sensor is a thermoelectric substance, which may, in the case of change of the human body's received infrared intensity, lose the charge balance and start to release current, thus obtaining the human sensing signals
Implementation Method 2
an aluminum radiator frame, which is assembled at lower part of the casing; said LED is mounted onto said aluminum radiator frame
