Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the laser line is used to mark points of interest on the jobsite surface, then the point transfer function is achieved, but the laser line is difficult to see in bright-lighting conditions or long distances
Solution Approach 1:
A reflective target is introduced as an intermediary element between the laser controller and the observer. The target reflects the laser line back to the observer, significantly enhancing the visibility of the laser line in bright-lighting conditions and at long distances, thereby maintaining measurement precision without compromising visibility
Solution Approach 2:
The reflective target is designed with high-reflectivity properties that enhance the contrast and visibility of the laser line. By utilizing the reflective characteristics of the target, the system effectively amplifies the laser line's visibility under various lighting conditions
2Adaptability or versatility
If the reflective target is positioned on rough, wet, uneven, or grassy surfaces, then the target can be placed on the jobsite surface, but finding the exact position of the point of interest becomes difficult and time consuming
Solution Approach 1:
The system incorporates feedback mechanisms where the laser controller continuously monitors the position of the reflective target and provides real-time guidance to the user. This feedback loop enables rapid adjustment and precise positioning of the target on challenging surfaces, eliminating trial-and-error processes
Solution Approach 2:
The reflective target is designed with a universal base or mounting mechanism that adapts to various surface types including rough, wet, uneven, or grassy surfaces. This multi-functional design allows the target to be securely positioned on any jobsite surface while maintaining measurement precision
3Productivity
If material is stored on the floor during construction, then construction activities can proceed, but the laser line is interrupted and users must remove material which is exhaustive and time consuming
Solution Approach 1:
The laser line measurement process is segmented into multiple sections. Instead of requiring a continuous unobstructed laser line across the entire measurement distance, the system divides the measurement into segments that can be taken around or between stored materials, allowing construction activities to continue without interruption
4Device complexity
If the plumb line laser pointer and reflective target are fixed in position, then the device structure is simple, but fine positioning in any horizontal direction is not possible
Solution Approach 1:
The device incorporates dynamic positioning mechanisms that allow the reflective target and plumb line laser pointer to be freely positioned in any horizontal direction. These mechanisms include adjustable mounts and movable platforms that provide fine positioning capability while maintaining a relatively simple device structure through modular design
