Solution Overview
Problem
Existing systems for detecting, identifying, and activating digital devices on a serial data bus are complex and require internal addressable switches and I/O ports, making them cumbersome for key control and management systems, and lack a simple means to associate LEDs with storage receptacles.
Innovation Solution
A reader board assembly circuit and method that uses a touch-and-hold connector, a microcontroller, a light-emitting source, and a host controller to selectively identify and activate digital devices on a serial data bus, eliminating the need for internal addressable switches and I/O ports, and associating LEDs with the storage receptacle, enabling easy detection and identification of digital devices with unique registration numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If internal addressable switches and I/O ports are used to identify digital devices, then device identification capability is improved, but system complexity increases
Solution Approach 1:
The patent extracts the identification function from complex internal addressable switches and I/O ports, replacing it with a simplified one-wire interface that uses unique digital registration numbers. This removes unnecessary complexity while maintaining precise device identification capability through the microcontroller's ability to read and distinguish these unique numbers.
Solution Approach 2:
The one-wire interface serves multiple functions: it provides unique device identification, enables communication between the microcontroller and digital devices, and allows for device activation. This multi-functional approach eliminates the need for separate addressable switches and I/O ports, reducing system complexity while maintaining identification precision.
2Ease of manufacture
If LEDs are associated with each carrier, then location indication is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the LED location indication function with the storage receptacle structure rather than associating LEDs with each individual carrier. This consolidation reduces the total number of LEDs needed and simplifies the system architecture, making it easier to manufacture while maintaining effective location indication capability.
3Reliability
If external power source is required for the system, then operational reliability is improved, but ease of operation deteriorates due to power connection requirements
Solution Approach 1:
The system is designed to draw power directly from the serial data bus through the one-wire interface, eliminating the need for separate external power connections. This self-powering approach simplifies installation and operation (improving ease of operation) while maintaining reliability through the stable power supply from the existing data bus infrastructure.
