Detection Sensor Shared Terminal for Setting Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection sensors require dedicated communication means to transmit setting information, increasing costs and complexity.
Innovation Solution
A detection sensor design that uses a common external connecting terminal for both outputting detection signals and inputting setting information, eliminating the need for dedicated communication means by selectively enabling input and output actions through a controlling means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated communication means are provided for transmitting setting information, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The external connecting terminal is designed to serve multiple functions: it acts as both an output terminal for detection signals and an input terminal for setting information. The terminal structure includes both an output circuit connected to the detection signal line and an input circuit connected to the setting information line, allowing a single terminal to handle bidirectional communication without requiring separate dedicated communication interfaces.
2Reliability
If dedicated communication means are provided for transmitting setting information, then communication stability is improved, but manufacturing cost increases
Solution Approach 1:
The invention merges the output function and input function into a single external connecting terminal. The terminal integrates the output circuit for detection signals and the input circuit for setting information, combining what would traditionally be separate communication channels into one unified interface, thereby reducing component count and manufacturing complexity.
3Object-affected harmful factors
If separate input and output terminals are used, then signal interference is reduced, but device complexity increases
Solution Approach 1:
The controlling means acts as an intermediary that manages the dual functionality of the external connecting terminal. It includes an outputting means that selectively outputs detection signals and an inputting means that selectively inputs setting information, with a selecting means that controls which function is active at any given time, preventing signal interference through temporal separation.

AI summary
A detection sensor and method enable a communication of setting information without a dedicated communication device. In particular, the output of an output signal as well as the reception of the setting information data are conducted using a common external connecting terminal, by selectively enabling a second output circuit, which a pressure sensor essentially includes, and an input circuit commonly connected to the external connecting terminal that is connected to the second output circuit.
