Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is distributed through QR codes or internet web pages, then information can be accessed by user devices, but the information cannot be updated in real-time and requires internet connectivity
Solution Approach 1:
The information distribution device pre-loads and stores information locally in its memory before it is needed by users. This allows the device to provide updated information immediately when users scan it, without requiring real-time internet connectivity at the moment of access. The device performs the information retrieval action in advance during periods when network availability is higher.
Solution Approach 2:
The information distribution device acts as an intermediary between the remote server and user devices. It receives information from the server, stores it locally, and then provides it to users who may not have internet access. This intermediary role allows information to be distributed even when the user-device connection to the internet is unavailable.
2Loss of information
If an information distribution device connects wirelessly to a remote server for real-time updates, then information can be updated in real-time, but the device requires power source and increases device complexity
Solution Approach 1:
The information distribution device incorporates multiple functions into a single unit: wireless communication capability to connect to remote servers, local storage memory to hold information, and a power source to enable autonomous operation. This multi-functionality allows the device to update information real-time while maintaining a relatively simple overall structure that can be integrated into existing pastry formats.
Solution Approach 2:
The device is designed to autonomously connect to remote servers, retrieve information updates, and store them locally without requiring manual intervention. The power source enables the device to perform these operations automatically, reducing the need for human maintenance and simplifying the operational complexity despite the added hardware components.
3Device complexity
If static information is provided through QR codes, then device complexity is minimized, but information cannot be updated and adaptability is reduced
Solution Approach 1:
The information distribution device transitions from a static information delivery system (like traditional QR codes) to a dynamic system that can automatically update its content. The device periodically connects to remote servers to retrieve new information and updates its local storage accordingly, enabling it to adapt to changing information requirements while maintaining a relatively simple physical structure.
