Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single infrared sensing probe is used on the streetlight, then the device structure is simple, but the sensing coverage is limited and cannot achieve 360-degree coverage
Solution Approach 1:
The patent divides the single sensing function into multiple independent infrared sensing probes arranged at different positions and angles on the light pole. Each probe covers a specific sector, and together they achieve comprehensive 360-degree coverage, resolving the contradiction between coverage area and device complexity
Solution Approach 2:
The patent transitions from a single-point sensing approach to a multi-dimensional sensing array. By positioning probes at different heights, angles, and radial positions on the light pole, the system creates three-dimensional spatial coverage, enabling 360-degree detection while maintaining reasonable device complexity
2Adaptability or versatility
If the sensing distance of the infrared sensing probe is fixed, then the device structure is simple, but the streetlight cannot adequately serve the diverse needs of users
Solution Approach 1:
The patent introduces adjustable sensing distance capability through mechanisms that allow the infrared sensing probe to change its detection range dynamically. This enables the streetlight to adapt to different user needs (e.g., pedestrian zones vs. vehicle roads) while the adjustment mechanism maintains reasonable complexity through standardized design
Solution Approach 2:
The patent enables change in the sensing parameter (detection distance) of the infrared probe to adapt to different application scenarios. By allowing this key parameter to be adjusted, the system achieves versatility for different user requirements while the adjustment mechanism is designed to maintain acceptable complexity levels
3Adaptability or versatility
If the brightness of the light source is fixed, then the device structure is simple, but the system lacks the capability to be adjusted according to user preferences and leads to energy waste
Solution Approach 1:
The patent transforms the fixed brightness light source into a dynamically adjustable system. The brightness can be modified in real-time based on detection results and user preferences, enabling adaptive lighting that reduces energy waste while the control system maintains reasonable complexity through integrated design
Solution Approach 2:
The patent implements a feedback control mechanism where the infrared sensing probe detects human presence or movement, and this information feeds back to the brightness control system. The system automatically adjusts light source brightness based on detected activity levels, achieving energy efficiency while the feedback loop is designed to maintain acceptable system complexity
4Ease of operation
If the infrared sensor controls the light source to emit light continuously when detecting human activity, then the user experience is improved, but electricity waste increases when no one is present
Solution Approach 1:
The patent implements periodic or conditional lighting activation based on detection cycles. Instead of continuous operation, the light source is activated only during detected human presence periods and deactivated during absence periods. This periodic action pattern reduces energy loss while maintaining automatic control convenience through the sensing system
Solution Approach 2:
The patent uses feedback from the infrared sensing probe to control light source operation. When the probe detects human activity, feedback signals activate the light source; when no activity is detected, the system transitions to standby state. This feedback-based control achieves convenient automatic operation while significantly reducing electricity waste through conditional activation
