Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a small-sized display device is integrated into the document, then the document maintains portability and compactness, but the display device cannot display complex character strings simultaneously
Solution Approach 1:
The display device dynamically switches between displaying different portions of character strings based on user input. The processor controls the display to show the first portion initially, then replaces it with the second portion upon receiving input signals, enabling the display to adapt its content over time rather than attempting to show all characters simultaneously.
Solution Approach 2:
The character string information is segmented into multiple portions (first portion and second portion) that are displayed sequentially. This segmentation allows the limited display capacity to present complex information by dividing it into manageable segments that can be shown in sequence rather than all at once.
2Device complexity
If the display device shows only a limited number of characters simultaneously, then the display remains simple and compact, but users cannot view complete character strings at once
Solution Approach 1:
The display device employs periodic action by sequentially showing different portions of the character string based on user input. The processor receives input signals and periodically updates the display content, switching between the first and second portions of character data, allowing users to access complete information through repeated interaction rather than displaying everything simultaneously.
3Adaptability or versatility
If the document uses contactless interface for communication, then the document enables wireless data transmission, but the document requires external electromagnetic fields for power and control
Solution Approach 1:
The antenna serves multiple functions: it acts as both a communication interface for contactless data transmission and as an energy harvesting device that converts electromagnetic fields into electrical energy. This multi-functionality allows the document to achieve wireless communication capability while using the same component for power supply, reducing overall system complexity.
4Loss of information
If the document processes character strings sequentially through user input, then the document can display complex information on small displays, but the user interaction time increases
Solution Approach 1:
The display device maintains continuous useful action by keeping the first portion of the character string displayed throughout the interaction process. When the user provides input, the system replaces the displayed portion with the next segment rather than clearing the display, ensuring that information presentation continues uninterrupted and users can follow the character string assembly in real-time.
