Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intelligent light sensing control is used to automatically turn on/off the lamp based on ambient light levels, then the lamp can respond to natural lighting conditions, but it becomes affected by other light sources at night causing incorrect operation
Solution Approach 1:
The control system is segmented into distinct functional blocks: voltage sensing function block for detecting solar panel voltage levels and timing function block for tracking sunlight movement. Each block operates independently with assigned control priorities, avoiding the interference problem of unified light sensing control.
Solution Approach 2:
The patent introduces a priority determination mechanism as an intermediary between the voltage sensing block and timing block. This mediator assigns control priorities based on working states, mediating the conflict between light sensing reliability and timing accuracy during nighttime operations.
2Illumination intensity
If the lamp operates continuously throughout the night based on light sensing, then lighting coverage is maintained, but energy consumption increases reducing solar-powered endurance
Solution Approach 1:
The timing function block implements periodic operation by tracking sunlight movement and controlling the lamp to operate during specific time windows when sunlight is available for charging, rather than continuous nighttime operation. This periodic action optimizes the balance between lighting coverage and energy conservation.
Solution Approach 2:
The control system dynamically adjusts the lamp's operating schedule based on real-time voltage sensing results and timing block calculations. The operating parameters change dynamically according to solar charging status and predicted sunlight availability, optimizing energy usage while maintaining necessary lighting coverage.
3Stability of the object's composition
If the lamp operates in preset current varying manner for extended duration, then lighting consistency is maintained, but energy depletes faster reducing operational endurance
Solution Approach 1:
The voltage sensing function block continuously monitors solar panel voltage and provides feedback to the control system. Based on this feedback, the timing block adjusts the lamp's operating schedule and current variation pattern, dynamically balancing brightness consistency with energy conservation to extend operational endurance.

AI summary
A lamp control method, a chip, a non-transitory computer-readable storage medium, a computer program, and an electronic device are provided. The lamp control method comprises acquiring a present working state of a lamp; determining a control priority of a voltage sensing function block and a control priority of a timing function block based on the present working state of the lamp to obtain a priority result; controlling the lamp to work based on the priority result. When the lamp is in the operating state, the control priority of the timing function block is configured to be higher than the control priority of the voltage sensing function block, such that the lamp is controlled to work based on the preset timing strategy, avoiding interference from other external light sources.
