Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If workers visually estimate distance to target, then operation is simple and quick, but measurement precision is poor leading to multiple vehicle repositions
Solution Approach 1:
The patent replaces the manual visual estimation method with an automated laser-based distance measuring system. The laser probe emits laser beams to measure distances to multiple nodes automatically, eliminating the need for workers to visually estimate distances and reducing measurement errors that lead to multiple vehicle repositions.
Solution Approach 2:
The patent introduces a control system as an intermediary between the laser probe and the worker. The control system processes distance measurements from the laser probe, determines whether the vehicle is positioned correctly for reaching multiple nodes, and provides automated guidance, reducing the complexity burden on the worker while improving measurement precision.
2Productivity
If vehicle is repositioned multiple times to reach multiple nodes, then distance estimation accuracy is maintained, but productivity decreases due to time loss
Solution Approach 1:
The patent performs preliminary distance measurements to multiple nodes before the worker commits to a vehicle position. The control system calculates whether the current vehicle position can service multiple nodes based on measured distances, allowing the worker to make an informed decision upfront and avoid multiple repositioning operations.
Solution Approach 2:
The patent implements a feedback loop where the laser probe continuously measures distances to multiple nodes, the control system processes this data to determine optimal vehicle positioning, and the information is fed back to guide the worker's positioning decisions. This feedback mechanism enables the vehicle to be positioned correctly the first time to service multiple nodes, reducing repositioning time and improving productivity.
