Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera supports both still image and moving image shooting with frame rate switching, then the functionality and versatility are improved, but the device complexity and operational complexity increase
Solution Approach 1:
The patent combines still image shooting mode and moving image shooting mode with multiple frame rate options into a single unified shooting device. The control unit integrates switching between different shooting modes (still image, moving image at various frame rates) through one control system, eliminating the need for separate devices or complex external controls for each mode.
Solution Approach 2:
The imaging device is designed to perform multiple functions: still image shooting, moving image shooting at multiple frame rates (30fps, 60fps, 120fps, 240fps), and seamless switching between these modes. The single device universal structure allows users to access all shooting modes without adding external equipment or complicating the basic device architecture.
2Adaptability or versatility
If multiple shooting modes and frame rates are available, then the adaptability is improved, but the ease of operation deteriorates due to complex switching
Solution Approach 1:
The control unit is pre-programmed with predetermined switching rules and logic for transitioning between shooting modes. When a user selects a shooting mode, the control unit automatically handles the switching sequence, frame rate adjustments, and parameter settings in advance prepared configurations, reducing the cognitive load and operational steps required by the user.
Solution Approach 2:
The control unit autonomously manages the complexity of mode switching and frame rate selection without requiring manual intervention for each parameter change. The system self-adjusts settings based on the selected mode, automatically transitioning between still image and moving image shooting, and selecting appropriate frame rates, thereby simplifying user interaction to basic mode selection only.
3Adaptability or versatility
If frame rate switching is supported during moving image shooting, then the versatility is improved, but the operational complexity increases
Solution Approach 1:
The patent implements dynamic frame rate switching capability that allows users to change frame rates during moving image shooting without stopping recording. The control unit dynamically adjusts the frame rate between 30fps, 60fps, 120fps, and 240fps in real-time based on user input, enabling flexible adaptation to different shooting scenarios while maintaining continuous operation.
Solution Approach 2:
The control unit supports periodic switching between different frame rates during moving image recording, allowing users to alternate between frame rates at regular intervals or on-demand. This periodic action capability enables creative shooting techniques such as slow motion segments followed by normal speed segments, while the control system automatically manages the transitions without interrupting the overall recording session.
