Removable Address Memory in Base Units for Fast Device Head Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security/automation systems face difficulties in efficiently and easily reconfiguring device addresses, especially when replacing device heads, often requiring specialized tools and conversion tables, and are cumbersome for installers due to the location of addressing devices in hard-to-reach places.
Innovation Solution
A removable and electrically readable addressing device is integrated into the base unit, allowing the device head to read the address from a removable addressing device, such as a card-shaped pennant, which can be swapped or reconfigured without needing special tools, maintaining the address with the base unit during head replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the addressing device is integrated into the base unit, then the address reconfiguration becomes easier and faster, but the device complexity increases
Solution Approach 1:
The addressing device is segmented from the device head and integrated into the base unit as a separate, removable component. This allows the addressing functionality to be independently managed in the base unit while keeping the device head simple and interchangeable.
Solution Approach 2:
The base unit acts as an intermediary between the device head and the addressing system. It houses the addressing device and provides the interface for address reading, separating the addressing function from the sensing function in the device head.
2Productivity
If the addressing device is made removable, then the address changes become faster and more flexible, but the reliability of address retention may be compromised
Solution Approach 1:
The addressing device is pre-programmed with a unique address before being installed in the base unit. This preliminary configuration ensures that the address is already set and retained, eliminating the need for field programming and ensuring reliability while maintaining removability.
Solution Approach 2:
The addressing device contains a memory copy of the address information that is read by the device head. This copying mechanism allows the address to be stored in a removable component while ensuring it is reliably transferred to the device head during operation.
3Measurement precision
If the addressing device is located in the base unit, then the address reading becomes more accurate, but the ease of access for reconfiguration deteriorates
Solution Approach 1:
The addressing device is segmented as a separate, removable component within the base unit. This segmentation allows it to be easily accessed and replaced while maintaining its integrated functionality for accurate address reading.
Solution Approach 2:
The addressing device transitions from a static integrated component to a dynamic removable component. It can be easily inserted and removed from the base unit, providing flexibility for reconfiguration while maintaining its function during operation.

AI summary
Example implementations include an addressable device having a base unit mountable on a structure and a device head removably mountable onto the base unit. A removable addressing device is removably mountable onto the base unit and comprises at least one memory storing an address for the addressable device. When the device head and the removable addressing device are mounted onto the base unit, the device head is electrically connected with the removable addressing device and is configured to read the address stored on the at least one memory of the removable addressing device.
