Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a microcomputer and data processing system are used to enable various image and audio projections, then the functionality and content diversity are improved, but the device complexity and operation steps increase
Solution Approach 1:
The patent extracts the complex microcomputer data processing system from the core functionality and replaces it with a simpler mechanical rotation mechanism. The mapping disc with coded regions rotates to select different images and audio, eliminating the need for complex software interfaces and data processing while maintaining content diversity.
Solution Approach 2:
The system uses the rotation of the mapping disc itself to trigger the selection of images and audio through mechanical coding regions. The circuit board automatically reads the code from the rotating disc and activates corresponding images and audio without requiring user input or complex control procedures, making the system self-serveing.
2Device complexity
If manual operation is used to select and play music with each picture, then the device simplicity is maintained, but the synchronization between picture and audio is poor
Solution Approach 1:
The patent merges the image selection and audio selection into a single unified operation. The mapping disc combines both image codes and audio codes in one rotation, so that when the disc rotates to a specific position, both the corresponding image and audio are automatically selected and synchronized without separate manual operations.
Solution Approach 2:
The circuit board reads the code from the rotating mapping disc in real-time and provides feedback control to simultaneously activate the corresponding image and audio outputs. This feedback mechanism ensures precise synchronization between the selected image and audio based on the disc's rotation position.
3Adaptability or versatility
If the mapping disc rotates to change patterns, then the picture diversity is improved, but the audio synchronization with projection content is not provided
Solution Approach 1:
The mapping disc serves multiple functions simultaneously: it selects images, selects audio, and provides synchronization timing all through a single rotation mechanism. The disc is divided into regions with different codes that correspond to different images and audio tracks, allowing one component to perform multiple functions that were previously separate.
Solution Approach 2:
The patent embeds both image codes and audio codes within the same mapping disc structure. The disc contains nested coding regions where image information and audio information are integrated together, allowing the rotation of a single disc to control both image projection and audio playback with perfect synchronization.
