Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional intrusion detectors are used, then intrusion detection capability is provided, but the detectors are visible and easy to detect by intruders
Solution Approach 1:
The transceiver element is housed within a magnetic contact assembly housing that is designed to be mounted in conjunction with a magnet component. The housing contains recesses that receive and conceal the transceiver element, integrating it within the overall magnetic contact assembly structure, making it difficult to distinguish from the functional components.
Solution Approach 2:
The housing is designed with specific local features including recesses that conceal the transceiver element and positioning features that align with the magnet component. The magnet component itself serves as a distraction element, drawing attention away from the concealed transceiver element located in a specific local region of the housing.
2Device complexity
If wireless communication is used, then installation complexity is reduced, but communication reliability may be compromised due to interference
Solution Approach 1:
The transceiver element is extracted as a separate functional component within the housing, allowing it to be positioned optimally for wireless communication while maintaining physical integration with the magnetic contact assembly. This separation enables the antenna to be positioned for optimal signal transmission while the housing provides shielding from interference.
Solution Approach 2:
The housing acts as an intermediary structure that provides physical protection and electromagnetic shielding for the transceiver element. The magnet component serves as a secondary intermediary that distracts potential intruders and provides functional magnetic contact capability while the transceiver operates independently within the housing.
3Ease of operation
If the transceiver element is exposed, then wireless communication functionality is achieved, but the overall assembly width increases
Solution Approach 1:
The transceiver element is nested within the housing structure, which is designed to align with and be mounted alongside the magnet component. The housing contains the transceiver element in a recessed position, ensuring that the overall assembly width is determined by the magnet component dimensions rather than the transceiver element dimensions.
Solution Approach 2:
The transceiver element is positioned within the housing in a manner that utilizes the depth dimension rather than increasing the width dimension. The antenna extends from the housing in a controlled manner to provide wireless communication capability without significantly increasing the overall assembly width, as the primary width is constrained by the magnet component mounting dimensions.
