Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users leave a digital television without turning it off, then the television remains on consuming energy, but differentiated services and personalized applications cannot be provided resulting in poor user experience
Solution Approach 1:
The system performs preliminary detection of user presence using sensors (camera, pressure sensor, gravity sensor) before the user actually leaves the television. Based on this preliminary detection, the system proactively transfers media playback to a second terminal (mobile phone) before the television is turned off, thus providing personalized services without unnecessary energy consumption.
Solution Approach 2:
The patent introduces a media playback system as an intermediary between the digital television and the user's mobile terminal. This intermediary system detects user presence, manages media information transfer, and coordinates playback across multiple devices, enabling personalized services while optimizing energy usage.
2Use of energy by stationary object
If the digital television is turned off when leaving, then energy consumption is reduced, but seamless playback transition to other devices cannot be achieved resulting in poor user experience
Solution Approach 1:
The system performs preliminary detection of user absence using sensors (camera, pressure sensor, gravity sensor) and proactively transfers media playback to a second terminal before the television is turned off. This preliminary action ensures seamless playback continuity without requiring the television to remain on for energy-intensive operations.
Solution Approach 2:
The media playback system acts as an intermediary that manages the transition of media information from the digital television to the user's mobile terminal. It detects user presence/absence, initiates transfer protocols, and coordinates playback synchronization, enabling seamless operation while allowing the television to be turned off for energy savings.
3Adaptability or versatility
If media playback is transferred between terminals based on location detection, then personalized services are provided, but system complexity increases due to multiple detection mechanisms
Solution Approach 1:
The patent segments the detection function into multiple independent sensors (camera for image recognition, pressure sensor for contact detection, gravity sensor for orientation detection). Each sensor independently detects different aspects of user presence, and the media playback system integrates these segmented detection results to make transfer decisions, thereby providing personalized services while managing system complexity through functional segmentation.
4Ease of operation
If multiple sensors are used to detect user presence for seamless playback, then user experience is improved, but device complexity and cost increase
Solution Approach 1:
The system segments the user presence detection function across multiple sensors (camera, pressure sensor, gravity sensor), with each sensor handling a specific detection task. This segmentation allows the system to achieve comprehensive detection capability while keeping each individual sensor component relatively simple and cost-effective.
Solution Approach 2:
The media playback system is designed with multi-functionality to handle various detection inputs (image data from camera, pressure data from pressure sensor, gravity data from gravity sensor) and unify them into a single user presence determination logic. This universal design allows the system to improve user experience through multiple sensors while avoiding the need for separate processing systems for each sensor type.

AI summary
A media playback method, so as to implement seamless playback of media information, is presented. The media playback method includes: determining a first location relationship between a target object and a first terminal; when the first location relationship meets a first preset condition, determining a second location relationship between a second terminal and the target object; and when the second location relationship meets a second preset condition, sending media information currently played on the first terminal to the second terminal, to enable the second terminal to play the media information. By using the foregoing technical solution, seamless playback of media information among multiple screens is implemented, thereby providing personalized data services and applications to a target object, and improving efficiency of acquiring media information by a target object.
