Configurable Detection Device Adapter for Signal Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection devices have a multitude of variants, leading to a high number of references, and previous solutions only reduce this number by half without accounting for multiple configurable parameters.
Innovation Solution
A detection device with a configurable detector and adapter system, utilizing mechanical selection means such as conductive pins and a mechanical polarizer, and configuration means like a movable part with a pivotable keying device, to select and assign various output signal types and ranges, allowing for multiple configuration variants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple detector variants are offered to adapt to all types of situations and environments, then the detector can accommodate different housing types, mounting options, ranges, output types, and logic configurations, but the number of references increases significantly
Solution Approach 1:
The patent implements a universal detector body that can perform multiple functions through interchangeable adapters. The single detector unit supports various housing types (cubic or cylindrical), mounting options (flush or non-flush), and output configurations by accepting different adapters, thereby eliminating the need for multiple specialized detector references while maintaining full adaptability to different application requirements
Solution Approach 2:
The detector system is segmented into a universal detector body and separate configurable adapters. The adapter serves as an independent module that can be selected and attached based on specific application needs, allowing the main detector unit to remain standardized while providing customization through modular adapter selection
2Device complexity
If two separate adapters are used to connect different outputs of the detector, then the number of references is reduced by half, but multiple configurable parameters cannot be accommodated
Solution Approach 1:
The adapter is designed as a multi-functional component that simultaneously handles multiple configuration parameters including output type selection (PNP/NPN), logic configuration (NO/NC), and mounting style adaptation. This single adapter replaces what would otherwise require multiple specialized adapters, enabling the system to accommodate various configurable parameters without increasing the number of adapter references
3Adaptability or versatility
If a single adapter with mechanical selection means is used, then multiple output signal types can be selected, but the adapter structure becomes more complex
Solution Approach 1:
The adapter incorporates a movable configuration element that can be positioned in different locations to select between various output signal types. This dynamic positioning mechanism allows the adapter to reconfigure its internal connections based on the selected output type (PNP NC, NPN NC, NPN NO, PNP NO, or DC two-wire), providing versatility through a single adaptable structure rather than requiring multiple fixed adapters

AI summary
The device has an adapter (70) provided on a detector (60), where the adapter comprises a mechanical selection unit to select a type of output signal of the detection device at terminals of an external connector i.e. M12 type external connector, that conforms a standard of a IEC60947-5-2. A configuring unit allots a given configuration to the detector. Conductive pins (11) and a mechanical polarizing slot are formed on the adapter with respect to pins (700).
