Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems require complex configuration processes due to the presence of user controls and displays in access control terminals, which are rarely used after initial setup, leading to inefficiencies and increased production costs.
Innovation Solution
An integrated circuit card with an antenna, communication circuit, and electromechanical switches that allow for radio-based wireless data exchange, featuring a secure element with a processor and memory, enabling power management through energy harvesting and selective component activation based on switching states, eliminating the need for user controls and displays in external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access control terminals include user controls and displays for configuration, then configuration capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the configuration capability from the access control terminal and relocates it to the integrated circuit card. The card now contains the user controls and display, while the terminal is simplified to only perform authentication functions. This extraction resolves the contradiction by removing complexity from the terminal while preserving configuration capability in the card.
Solution Approach 2:
The patent inverts the traditional architecture where the terminal had configuration capabilities and the card was simple. Now the card has the complex configuration interface and the terminal is simplified. This inversion resolves the technical contradiction by placing the user controls and display in the card rather than the terminal.
2Adaptability or versatility
If access control terminals include user controls and displays, then configuration functionality is improved, but production costs increase
Solution Approach 1:
By extracting the user controls and display from the terminal and placing them in the integrated circuit card, the patent reduces the bill of materials and manufacturing complexity for the terminal. The card, being a standardized component, can incorporate these elements more efficiently, thereby reducing overall production costs while maintaining configuration functionality.
Solution Approach 2:
The integrated circuit card serves multiple functions: it acts as both an authentication credential and a configuration interface for the terminal. This multi-functionality eliminates the need for separate configuration devices, reducing overall system cost while maintaining full configuration capability.
3Adaptability or versatility
If access control terminals have user controls and displays, then configuration capability is improved, but energy consumption increases
Solution Approach 1:
The display and user controls in the integrated circuit card are activated only periodically during configuration operations, rather than being continuously active. The card enters low-power states between interactions, significantly reducing energy consumption while maintaining configuration capability when needed.
Solution Approach 2:
The integrated circuit card autonomously manages its own power consumption by controlling when the display and user controls are active. The card detects when configuration is needed and activates these components only during such events, eliminating the need for continuous power supply and reducing overall energy consumption.
