Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single decoder is used for information acquisition, then the device complexity is reduced, but the adaptability to handle various information acquisition methods (geometric patterns and optically changing time series patterns) deteriorates
Solution Approach 1:
The decoder system is segmented into multiple independent decoders: a first decoder for geometric patterns (QR codes) and a second decoder for optically changing time series patterns (visible light communication). Each decoder is specialized for a specific information acquisition method, allowing the system to handle multiple types of information without requiring a single complex universal decoder.
Solution Approach 2:
The imaging device serves multiple functions by capturing both geometric patterns and optically changing time series patterns using the same camera. The imaging controller coordinates the imaging device to acquire different types of information through different acquisition methods, making the overall system universal while maintaining specialized decoders for each method.
2Adaptability or versatility
If multiple decoders are used for different information acquisition methods, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The decoding functionality is segmented into separate specialized decoders rather than a single monolithic decoder. The first decoder handles geometric patterns while the second decoder handles temporal light pattern changes, allowing each component to be optimized for its specific task while maintaining overall system manageability.
Solution Approach 2:
The imaging controller acts as an intermediary that coordinates between the imaging device and the multiple decoders. It manages the imaging process to capture both geometric and temporal patterns, and directs the appropriate decoder to process each type of information, simplifying the interaction between multiple components.
3Productivity
If the imager captures both geometric patterns and optically changing time series patterns simultaneously, then the productivity of information acquisition is improved, but the imaging control complexity increases
Solution Approach 1:
The imaging controller is configured to capture both geometric patterns and optically changing time series patterns in advance during the imaging process. By preparing multiple types of information simultaneously rather than sequentially, the system improves productivity while the controller manages the complexity through predetermined capture sequences.
Solution Approach 2:
The imaging device continuously captures information including both geometric and temporal pattern data without interruption. This continuous acquisition of multiple information types simultaneously maximizes productivity, while the imaging controller maintains manageable complexity through uninterrupted operational flow.

AI summary
The imager and controller of an information apparatus images the back face of another information apparatus to acquire the manufacturing number of the other information apparatus corresponding to the two-dimensional bar code provided on the back face of the other information apparatus and acquire visible light information corresponding to blinking of light emitted by the light emitter arranged on the back face of the other information apparatus. Furthermore, the controller controls the imager so as to be able to image the two-dimensional bar code and the light emitted by the light emitter.
