Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional construction cones use passive warning effects (color marks or reflective strips), then the structure is simple, but the warning effect is poor at night or in bad weather
Solution Approach 1:
The patent applies dynamics by making the construction cone rotatable so that the detection angle and warning coverage are dynamically changed. The cone body can rotate 360 degrees, allowing the distance sensor and warning devices to cover all directions over time, transforming a static limited-coverage system into a dynamic full-coverage system.
Solution Approach 2:
The patent uses periodic action through the rotational movement of the cone body. The distance sensor periodically scans different directions as the cone rotates, and the warning devices (lights and sirens) are activated periodically when objects are detected in different sectors, ensuring continuous monitoring and warning coverage around the construction area.
2Reliability
If a distance sensor is added to enhance warning effect, then the warning capability is improved, but the alarm distance, range, and angle are limited by the installation position

3Reliability
If a warning lamp is added on top of the construction cone, then the visibility is improved, but the electricity consumption increases in fine weather and the warning effect cannot be adjusted responsive to environmental changes
Solution Approach 1:
The patent applies feedback by using environmental sensors (light sensor and humidity sensor) to detect ambient conditions and automatically adjusting the operation of the warning lamp and siren accordingly. When ambient light is sufficient or weather is clear, the warning devices are deactivated or operated at lower intensity, reducing energy consumption. When ambient light is low or weather is poor, the warning devices are activated at higher intensity, ensuring adequate visibility and warning effect.

AI summary
An intelligent construction cone includes a light pervious body rotatable relative to a body. A rotating device is mounted to the light pervious body and driven by a driving device to rotate the light pervious body. A distance detector sends a distance signal to a controller coupled to the driving device. The distance detector is jointly rotatable with the light pervious body to eliminate detection dead angle. A warning device is coupled to the controller and generates a warning message responsive to the distance signal. A lighting device is coupled to the controller and provides illumination. A light sensor and a humidity sensor are coupled to the controller and detect environmental brightness and environmental humidity, respectively. The warning message and intensity of the illumination are adjusted according to a distance between an object and the distance detector, the environmental brightness, and the environmental humidity.
