Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart functions are integrated into the main display device, then the device provides comprehensive functionality, but upgrading becomes complex and requires technical knowledge and additional equipment
Solution Approach 1:
The patent separates smart functions from the main display device by implementing them on a removable smart card. This segmentation allows the smart card to be independently upgraded without affecting the main device, thereby reducing upgrade complexity while maintaining adaptability. The smart card contains dedicated hardware and software for smart functions, enabling independent development and distribution of updates.
Solution Approach 2:
The patent extracts smart functions into a separate removable smart card component. This extraction allows the main display device to remain simple while the smart card handles all smart function operations. Upgrades are performed by replacing or updating the smart card, eliminating the need for complex technical procedures involving the main device.
2Adaptability or versatility
If smart functions are integrated into the main display device, then unified control is achieved, but upgrade costs and development resources increase
Solution Approach 1:
By segmenting smart functions into a separate smart card, the patent enables independent development and manufacturing of smart function modules. This reduces the burden on main device manufacturers, as they can partner with specialized smart card providers. Upgrades only require smart card replacement, not main device recall or complex assembly, significantly reducing development and manufacturing costs.
Solution Approach 2:
The smart card is designed as a universal platform that can be used across different display device models. This multi-functionality approach allows a single smart card design to serve multiple device types, reducing development costs through economies of scale. The standardized smart card interface enables widespread adoption and shared development resources.
3Ease of manufacture
If the system-on-chip (SoC) is designed for basic functions, then manufacturing is simpler, but the device becomes obsolete faster as smart functions evolve
Solution Approach 1:
The patent segments the device into a basic SoC for core functions and a separate smart card for evolving smart functions. This allows the SoC to remain simple and cost-effective for manufacturing, while the smart card handles advanced features. When smart functions need updating, only the smart card is replaced, extending the overall device lifespan without requiring SoC upgrades.
Solution Approach 2:
The smart card is pre-configured with the latest smart functions at the time of manufacture. This preliminary action ensures that devices start with current capabilities, and future updates are achieved by replacing the smart card rather than modifying the SoC. This approach preserves the simplicity of SoC manufacturing while ensuring the device remains current.
