Solution Overview
Problem
Video conferencing during the COVID-19 pandemic faced challenges such as impaired student-teacher engagement due to limited visibility, particularly because of technical difficulties like restricted camera viewing frames and student movement, which hindered facial expression visibility.
Innovation Solution
An electromagnetic payload orientation device (EPOD) with a rotor and stator, utilizing electromagnetic coils and a control circuit to induce relative rotation, constraining motion via guide tracks, allowing the payload to track users automatically, such as with a camera, to maintain the user's face within the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed camera is used for video conferencing, then the device complexity is low, but the user's face may move out of the frame reducing visibility
Solution Approach 1:
The patent replaces traditional mechanical pan-tilt-zoom mechanisms with an electromagnetic field-based system. Electromagnetic coils generate magnetic fields that interact with a magnetic rotor to achieve payload orientation and tracking, eliminating complex mechanical linkages, gears, and motors while maintaining the ability to dynamically adjust camera orientation for continuous user tracking.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the control system and the payload orientation mechanism. The electromagnetic coils act as intermediaries that convert electrical signals into magnetic fields, which then interact with the magnetic rotor to produce controlled motion, providing smooth and precise orientation adjustment without direct mechanical coupling.
2Manufacturing precision
If electromagnetic coils are used to induce rotation, then the payload orientation control precision is improved, but the power consumption increases
Solution Approach 1:
The patent employs periodic activation of electromagnetic coils to achieve payload orientation. Instead of continuous power application, the system uses pulsed or periodic electromagnetic field generation to induce rotor rotation, reducing overall power consumption while maintaining precise orientation control through timed electromagnetic actuation sequences.
Solution Approach 2:
The patent implements dynamic electromagnetic field generation where the coil activation patterns are continuously adjusted based on real-time tracking requirements. The system modulates the electromagnetic field strength and timing dynamically, applying power only when and where needed to achieve the desired orientation change, thereby optimizing energy efficiency while maintaining control precision.

AI summary
Apparatus and associated methods relate to an electromagnetic steered orientation device. In an illustrative example, an exemplary electromagnetic payload orientation device (EPOD) includes a rotor, a stator, and a payload mounted on the rotor. The rotor, for example, may be coupled to a magnetic source. For example, the stator may include electromagnetic coils operable by a controller circuit to induce relative rotation between the rotor and the stator. In some examples, the rotor is a sphere provided with one or more guide tracks on an outer surface, and the stator is a concentric shell surrounding the sphere provided with at least one follower corresponding to the guide tracks such that a relative rotation between the rotor and stator is constrained by the guide track to follow a predetermined motion profile. Various embodiments may advantageously provide a substantially smooth and low voltage mechanism to orient the payload.
