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 seldom 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 enable radio-based wireless data exchange, powered by an external device, and a secure element for secure data transmission and reception, 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 and production costs increase
Solution Approach 1:
The patent extracts the configuration control elements (display and user controls) from the access control terminal and relocates them to the integrated circuit card. The terminal itself becomes a simple reader that only performs authentication, while the card contains the configuration interface. This separation resolves the contradiction by maintaining configuration capability while eliminating the complexity and cost of having these elements in the terminal.
Solution Approach 2:
The integrated circuit card acts as an intermediary that bridges the user and the access control terminal. Instead of the terminal directly providing configuration interfaces, the card serves as a portable configuration device that communicates with the terminal. This mediator approach allows configuration functionality to exist without requiring complex terminal design.
2Adaptability or versatility
If access control terminals include display and user controls, then configuration functionality is improved, but production costs increase
Solution Approach 1:
By extracting the expensive display and control components from the terminal and placing them in the card, the patent significantly reduces terminal production costs. The terminal becomes a simpler device with fewer components, while the card (which is already a complex component) absorbs the configuration functionality costs.
Solution Approach 2:
The integrated circuit card serves multiple functions: it acts as an identification credential, a configuration device, and a communication interface. By making the card multi-functional, the patent eliminates the need for separate configuration devices, thereby reducing overall system costs while maintaining full configuration capability.
3Ease of operation
If access control terminals have configuration interfaces, then ease of configuration is improved, but device complexity increases
Solution Approach 1:
Instead of the terminal providing configuration interfaces to the user, the patent inverts the approach by having the card provide the configuration interface. The user interacts with the card's interface rather than the terminal's interface. This inversion maintains ease of configuration while simplifying the terminal's design and reducing its complexity.
