Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an interactive device is embedded in each book, then interactivity is provided, but production cost increases and device quality decreases
Solution Approach 1:
The interactive system is divided into two segments: a reusable electronic device and a simple book with identifier. The book contains only a book-identifier (passive element), while the electronic device contains all active components (processor, memory, output devices). This segmentation allows books to be manufactured simply without embedded electronics, reducing production costs while maintaining interactivity through the external device.
Solution Approach 2:
Instead of embedding expensive interactive devices in each book, the system uses a single electronic device that can be attached to multiple books. The book-identifier acts as a simple copyable element that can be replicated in books without complex electronics, allowing the same high-quality electronic device to serve multiple books sequentially.
2Adaptability or versatility
If buttons or touch positions are used for user input, then interaction is enabled, but the number of interaction possibilities is limited
Solution Approach 1:
The electronic device incorporates a touchscreen display that serves multiple functions: displaying book content, providing virtual buttons, enabling touch input, and showing feedback. This single multi-functional component replaces multiple dedicated buttons and input mechanisms, significantly increasing interaction possibilities while actually reducing overall device complexity.
Solution Approach 2:
The user interface is dynamic and adaptive, with virtual buttons and interaction elements that can change position, number, and function based on the book content and user preferences. Unlike fixed physical buttons, the touchscreen allows the interface to be reconfigured for different interaction scenarios, enabling unlimited interaction possibilities.
3Measurement precision
If an active page-identifier device is included in each book, then page identification is achieved, but the book becomes cumbersome and requires frequent battery changes
Solution Approach 1:
The active page-identifier device is extracted from the book and placed in the external electronic device. The book retains only a passive book-identifier (such as a magnetic strip or RFID tag), eliminating the need for batteries and complex electronics in the book itself. This extraction resolves the contradiction by providing accurate page identification through the external device while keeping the book simple and easy to use.
Solution Approach 2:
The book-identifier in the book is a simple, passive, and inexpensive element that does not require power. It can be a magnetic strip, RFID tag, or other passive identifier that is cheap to manufacture and does not need replacement. The complex, battery-powered detection and processing is done in the reusable external device, separating the disposable/simple book component from the durable electronic component.
