Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solar lamp integrates insect control functionality, then the device provides dual functionality (lighting and insect control), but the device complexity increases
Solution Approach 1:
The patent combines a solar lamp and an electric insect control trap into a single integrated device. The lamp housing contains both illumination components (LEDs, solar cells, battery) and insect control components (electrocuting grids, insect-attracting lights). This merging of previously separate devices into one unified system provides dual functionality while managing the inherent complexity through shared structural elements and housing.
Solution Approach 2:
The solar lamp device is designed to perform multiple functions: it provides illumination through high-power LEDs, controls insects through electrocuting grids and attractant lights, and uses solar cells for energy harvesting. The single device serves as both a lighting source and an insect control trap, embodying the universality principle by making one object perform several different functions that were previously required separate devices for.
2Illumination intensity
If the lamp uses high-power LEDs for illumination, then the illumination intensity increases, but the energy consumption increases
Solution Approach 1:
The illumination LEDs are designed to operate periodically rather than continuously. The control circuit activates the high-power LEDs only when ambient light levels are below a predetermined threshold (darkness detection) and/or when motion is detected by the motion sensor. This periodic operation allows the system to deliver high illumination intensity when needed while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system incorporates ambient light sensors and motion sensors that provide feedback to the control circuit. The light sensor detects ambient light levels and feedback this information to control the illumination LEDs, activating them only when darkness is detected. The motion sensor provides feedback about detected motion, triggering the LEDs and insect control functions. This feedback mechanism ensures high illumination intensity is provided only when and where needed, optimizing energy usage.
3Reliability
If the lamp activates insect control functions continuously, then the insect control effectiveness increases, but the energy waste increases
Solution Approach 1:
The insect control functions (electrocuting grids and insect-attracting lights) are activated periodically based on motion detection and ambient light conditions rather than continuously. The motion sensor detects the presence of moving objects (insects or other motion) and triggers the insect control functions only when motion is detected. This periodic activation maintains insect control effectiveness by responding to actual insect presence while avoiding energy waste from continuous operation when no insects are present.
Solution Approach 2:
The system uses the motion sensor to automatically detect and respond to insect presence without continuous operation. When motion is detected, the insect control functions self-activate to address the detected insects. This self-service approach allows the system to maintain effectiveness by responding to actual insect activity while minimizing energy waste through automatic on-demand activation rather than continuous operation.

AI summary
A solar lamp has illumination functionality and insect control functionality. The lamp has a main body comprising a main housing, a rechargeable battery housed within lamp for powering the electronic functions of the lamp, device electronics housed within the lamp for controlling the electronic functions of the lamp in a plurality of states comprising an OFF state and an ON state, and a support attached to the lamp, the support containing solar cells for harvesting solar energy and recharging the rechargeable battery and also for detecting a level of ambient light. A transparent panel is disposed at a front of the main body, the panel disposed over a printed circuit board (PCB) on which are disposed a plurality of high-power LEDs for illumination. One or more extension housings are attached to the main body, each extension housing containing an inner grid and an outer grid for electrocuting insects and one or more insect-attracting lights for emitting insect-attracting wavelengths of light. A manual electrical switch is disposed on the lamp for manually selecting a state from the plurality of states. The solar cells, rechargable battery, manual electrical switch, inner grid, outer grid, insect-attracting lights and high-power LEDs are electrically and operatively connected to the device electronics. When the OFF state is selected by the manual electrical switch, the inner grid, outer grid, insect-attracting lights and high-power LEDs are off. When the ON state is selected, the inner grid, outer grid, and insect-attracting lights are on, and if the solar cells are detecting a level of ambient light below a predetermined level, the high-power LEDs are also on.
