Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the playback speed of fitness course content is fixed, then the system complexity is reduced, but the user experience deteriorates due to inability to adjust to different exercise paces
Solution Approach 1:
The patent implements dynamic playback speed adjustment by allowing users to change video playback speed during exercise sessions. The system provides multiple speed options (0.5x, 0.75x, 1.0x, 1.25x, 1.5x) and enables smooth transitions between speeds without requiring session interruption, making the system adaptable to different exercise paces and user needs.
Solution Approach 2:
The patent changes the playback speed parameter of video content to accommodate different user requirements. By adjusting the playback speed parameter, the system maintains a single unified course structure while providing personalized viewing experiences, thus improving user experience without significantly increasing system complexity.
2Ease of operation
If multiple tuning steps are required for playback speed adjustment, then the playback speed control precision is improved, but the operation complexity increases leading to poor user experience
Solution Approach 1:
The patent provides preliminary action by pre-setting multiple playback speed options (0.5x, 0.75x, 1.0x, 1.25x, 1.5x) that are immediately available to users. This eliminates the need for gradual step-by-step tuning, allowing users to directly select their desired speed without multiple adjustment steps, thereby simplifying operation while maintaining control precision.
Solution Approach 2:
The system enables self-service by allowing users to independently adjust playback speed according to their own exercise pace requirements. The interface provides clear speed options that users can select without requiring complex configuration or multiple tuning steps, making the adjustment process intuitive and user-friendly.
3Adaptability or versatility
If fitness courses are provided in a single form, then the device complexity is reduced, but the adaptability deteriorates as users lack choice in video presentation style
Solution Approach 1:
The patent segments video content into different types (cartoon animation and real human demonstration) within the same fitness course. Users can switch between these segmented video types during exercise sessions, providing adaptability and choice without requiring completely separate course structures. This segmentation approach maintains course unity while offering presentation style variety.
Solution Approach 2:
The patent implements multi-functionality by making the video playback system capable of displaying multiple video types (cartoon and real human demonstration) within a single unified course framework. The same course structure supports different video presentation styles, allowing users to choose their preferred visual format while maintaining the integrity and coherence of the fitness program.
Data Source
AI summary
A fitness coaching method, system and terminal are provided. The fitness coaching method includes the following steps: acquiring first option data of a user; retrieving a demonstrative video, and reading VideoSpeedData in the fitness coaching system according to a unique identifier of the demonstrative video to obtain a set playback speed; playing the demonstrative video, and generating synchronous count text and speech by a Text to Speech (TTS) module; acquiring second option data of the user, tuning the set playback speed, packaging to obtain a latest VideoSpeedData to be stored in SharedPreferences of the fitness coaching system, wherein a tuned playback speed is used as the set playback speed corresponding to the demonstrative video when the demonstrative video is selected a next time.
