Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the construction robot operates in high-dust environments to perform construction tasks, then productivity is improved, but sensor contamination occurs leading to reduced measurement precision
Solution Approach 1:
The cleaning device performs preliminary cleaning actions before dirt accumulation significantly degrades sensor performance. The system proactively removes dust and contaminants from sensor surfaces through suction, blowing, and wiping mechanisms, preventing measurement precision loss while maintaining continuous construction operations
Solution Approach 2:
The cleaning device operates continuously or periodically to maintain sensor cleanliness throughout the construction process. By integrating the cleaning mechanism with the robot's operational cycle, the system ensures uninterrupted monitoring capability while performing construction tasks in dusty environments
2Measurement precision
If the sensor is positioned close to the work position for better monitoring, then measurement precision is improved, but dust exposure increases leading to faster contamination
Solution Approach 1:
The cleaning device acts as an intermediary between the sensor and the dusty environment. By positioning the cleaning mechanisms (suction device, blower, wiper) near the sensor, they create a protective zone that actively removes dust particles before they can contaminate the sensor surface, enabling the sensor to operate close to the work position without suffering from increased dust exposure
3Measurement precision
If a cleaning device is added to remove dust from sensors, then measurement precision is maintained, but device complexity increases
Solution Approach 1:
The cleaning device integrates multiple cleaning functions (suction, blowing, wiping) into a single unified system mounted on the robot arm. By combining these mechanisms and controlling them through a single control unit, the system maintains sensor cleanliness without proportionally increasing overall device complexity
Solution Approach 2:
The cleaning device is designed to serve multiple purposes: the suction device removes loose dust, the blower prevents dust settlement, and the wiper cleans adhered contaminants. This multi-functional approach allows a single integrated system to address various contamination scenarios, reducing the need for separate cleaning mechanisms
Applied Scientific Principles
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 cleaning device effectively removes dirt and dust from sensor surfaces, allowing the construction robot to accurately monitor and execute tasks even in high-dust environments, thereby enhancing safety and task reliability.
Implementation Method 1
The cleaning device may comprise a suction device. The suction device may, for example, be a vacuum cleaner.
Implementation Method 2
Alternatively or additionally, it is also conceivable for the cleaning device to include a blowing device.
Implementation Method 3
It's also conceivable that the cleaning device includes a wiper. Stubborn dirt on the sensor surface, which, for example, cannot be vacuumed or blown away, can then be wiped off the sensor surface with the help of the wiper.
