Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical counter-balancing is used to position display devices, then the device can be positioned at different angles, but the system becomes complex and difficult to control precisely
Solution Approach 1:
The patent replaces complex mechanical counter-balancing linkages with an electronic control system that uses motors to actuate pivotable components. The controller receives sensor data and sends commands to motors, eliminating the need for complex mechanical CAMs or linkages to coordinate multiple axes. This substitution maintains the ability to position the display at various angles while dramatically reducing mechanical complexity.
Solution Approach 2:
The patent implements a feedback control system where sensors detect the position of pivotable components and provide data to the controller. The controller processes this sensor data and adjusts motor actuation accordingly to achieve precise positioning. This closed-loop feedback mechanism enables accurate control of display positions without requiring complex pre-calibrated mechanical linkages.
2Stability of the object's composition
If friction components are added to compensate for counter-balancing mismatch, then the device stability improves, but the user experience deteriorates due to poor feel when adjusting
Solution Approach 1:
The patent replaces friction-based mechanical compensation with electronic control. Motors provide precise actuation forces to counter-balance the display at any position, eliminating the need for friction components. This electronic approach maintains stability while providing smooth, controlled movement that enhances user experience compared to the gritty feel of friction-based systems.
Solution Approach 2:
The patent implements dynamic counter-balancing where the control system continuously adjusts motor forces based on real-time sensor feedback. This dynamic adjustment allows the system to maintain stability at any position while providing smooth, natural movement during adjustment. The electronic system can adapt forces moment-to-moment, creating a responsive and pleasant user experience.

AI summary
In embodiments of electronic compensated pivot control, a computing device includes a device housing that is integrated with a display device, and the device housing tilts for multiple display positions. Pivotable components pivot in coordination to position the display device in a display position, and sensors detect positioning inputs that are received to re-position the display device. Actuators are implemented for electronic actuation to drive the pivotable components to position the display device, and clutches are implemented to limit movement of the pivotable components. A pivot controller is implemented to receive input data corresponding to a user input to change a position of the display device, control the actuators based on the input data to assist with positioning the display device, receive an indication that the user input has stopped, and control the one or more clutches to hold the position of the display device.
