Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If advanced display information is rendered on portable communication devices, then information display quality is improved, but memory consumption increases
Solution Approach 1:
The patent segments information display into two distinct modes: automatic display mode for essential information that updates independently, and user-requested display mode for detailed information. This segmentation allows the system to load only necessary data into memory at any given time, reducing overall memory consumption while maintaining high display quality for both modes through selective data loading.
Solution Approach 2:
The system performs preliminary actions by pre-loading and caching information in the information buffer before it is actually needed for display. The automatic display mode operates on pre-fetched data, and when users request additional information, the system can quickly retrieve it from the buffer rather than loading everything into memory upfront, thus optimizing memory usage.
2Speed
If high bandwidth network connectivity is used to transfer information, then information transfer speed is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action through the automatic display mode, which periodically updates essential information without requiring continuous user interaction or high-bandwidth connections. The information buffer is updated periodically with essential data, allowing the device to maintain informative displays while using lower bandwidth and consuming less energy compared to continuously loading all possible information at high speed.
Solution Approach 2:
The patent extracts only the essential information needed for automatic display from the complete data set available through network connections. By separating essential information (loaded automatically) from detailed information (loaded on demand), the system reduces the amount of data that requires high-bandwidth transfer, thereby lowering energy consumption while maintaining fast transfer speeds for the extracted essential data.
3Quantity of substance
If volatile memory is increased to enable advanced information display, then display capability is improved, but device cost increases
Solution Approach 1:
The system implements dynamic memory management where the information buffer size and content are dynamically adjusted based on current display needs. Essential information for automatic display mode occupies a fixed, smaller portion of memory, while additional information for user-requested mode is loaded dynamically only when needed. This dynamic approach allows the device to provide advanced display capabilities with a smaller, more cost-effective memory configuration compared to systems that allocate fixed large memory capacities.
Solution Approach 2:
The patent changes the parameter of memory usage from a static, fixed allocation to a dynamic, demand-based allocation. The system monitors and adjusts the amount of information stored in the buffer based on display mode, user behavior patterns, and available resources. This parameter change enables the device to achieve advanced display functionality with optimized memory utilization, reducing the required memory capacity and thereby lowering manufacturing costs.
4Ease of operation
If automatic information display is implemented, then user convenience is improved, but radio link usage increases
Solution Approach 1:
The system applies partial action by implementing automatic display for only the essential portion of information that users most frequently need. Not all available information is automatically loaded or updated via radio link - only the critical subset required for automatic display mode. This partial approach maintains user convenience through automatic updates while significantly reducing radio link usage compared to systems that automatically load all available information.
Data Source
AI summary
A portable communication device equipped with a screen and a random access memory. The device receives a data stream through a radio link for automatically displaying information from the data stream on a display screen, without any user's request, a part of this information being stored in random access memory during a period of time that is longer than the duration of display and displays information from the data stream on the display screen, upon user's request, this information being stored in random access memory during the duration of display only.
