Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed calibration procedure with predetermined waypoints is used, then the robotic arm can operate with simple control logic, but it cannot adapt to variations in slide dimensions and positioning

Engineering Contradiction:
Improveadaptability to slide variationsVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system captures images of the slide at the current waypoint, detects the slide's actual position and dimensions, and uses this feedback to dynamically adjust subsequent waypoints. This closed-loop feedback mechanism enables the robotic arm to adapt to variations in slide positioning and dimensions while maintaining operational precision.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The calibration procedure transitions from a static, predetermined sequence of waypoints to a dynamic process where waypoints are continuously adjusted based on real-time slide detection. The system modifies the calibration path adaptively, allowing the robotic arm to respond to actual slide characteristics rather than following a rigid pre-programmed trajectory.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the robotic arm follows a predetermined calibration procedure, then the control logic remains simple, but handling precision deteriorates due to dimensional variations

Engineering Contradiction:
Improveslide handling precisionVSAvoidwaypoint adaptation complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system uses image capture and slide detection to obtain real-time feedback on slide position and dimensions. This feedback is processed to calculate corrected waypoints that compensate for dimensional variations, ensuring precise slide handling while managing complexity through automated image processing algorithms.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes the parameters of the calibration procedure, specifically the waypoint coordinates, based on detected slide characteristics. By adjusting these parameters in real-time according to actual slide dimensions and positioning, the system maintains high handling precision despite variations in slide specifications.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If adaptive waypoint adjustment is implemented, then handling accuracy improves, but the calibration process time increases

Engineering Contradiction:
Improvepick and place accuracyVSAvoidcalibration procedure time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary slide detection and waypoint adjustment before the robotic arm executes pick and place operations. By preparing adapted waypoints in advance based on detected slide characteristics, the system ensures high accuracy during actual handling while minimizing time loss through proactive rather than reactive adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adaptive waypoint adjustment operates continuously throughout the calibration and handling process rather than requiring separate adjustment phases. The robotic arm moves through calibration waypoints while image capture and waypoint adaptation occur in an integrated continuous process, maintaining useful action throughout and reducing overall calibration time.

Inventive Principle:
Principle #20Continuity of useful action
