Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constantly powered terminal connectors are prone to de-plating due to conductive solutions and pose safety risks in hazardous environments, making it difficult to detect unpowered peripherals without risking damage or user safety.
Innovation Solution
A detector system with a peripheral sensor on the terminal and a terminal sensor on the peripheral allows for power to be supplied only when a peripheral is detected, using passive or powered sensors to prevent de-plating and ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power is constantly supplied to the terminal connector, then powered and unpowered peripherals can be connected, but de-plating of contacts occurs due to conductive solutions
Solution Approach 1:
The patent implements dynamic power management by transitioning the terminal connector from a static constantly-powered state to a dynamic state where power is applied only when needed. The system uses a sensor to detect peripheral presence and controls power supply accordingly, applying power only when a peripheral is detected and removing it when no peripheral is present, thus preventing de-plating while maintaining compatibility with both powered and unpowered peripherals
Solution Approach 2:
The patent employs a feedback mechanism where a sensor continuously monitors the presence of a peripheral and provides information to the power control system. This feedback loop enables the system to adjust power supply status based on actual peripheral presence, ensuring power is supplied only when necessary for unpowered peripherals while preventing harmful continuous power application that causes de-plating
2Ease of operation
If power is constantly supplied to the terminal connector, then unpowered peripherals can operate, but safety risks increase in hazardous environments due to potential sparks
Solution Approach 1:
The system dynamically adjusts power supply status based on peripheral presence detection. When no peripheral is connected, the terminal connector remains unpowered, eliminating spark hazards in dangerous environments. When a peripheral is detected, power is applied to enable operation of unpowered peripherals, thus balancing safety requirements with operational needs
Solution Approach 2:
A sensor-based feedback system continuously monitors for peripheral presence and controls power supply accordingly. This feedback mechanism ensures power is applied only when a peripheral is detected, preventing sparks in hazardous environments when no peripheral is present while still enabling unpowered peripherals to operate when connected
3Reliability
If power is turned off to prevent de-plating, then contact damage is avoided, but the terminal cannot detect unpowered peripherals
Solution Approach 1:
The patent separates the detection function from the power supply function. The sensor system independently detects peripheral presence without requiring power to be applied to the connector, while the power supply is controlled separately based on detection results. This segmentation allows the terminal to detect unpowered peripherals through the sensor while keeping the connector unpowered to prevent de-plating
Solution Approach 2:
The sensor acts as an intermediary that enables peripheral detection without requiring power to be applied to the connector. The sensor detects the presence of unpowered peripherals through non-power-consuming means, allowing the system to identify connected devices while maintaining the connector in an unpowered state to prevent contact damage

AI summary
A client-host detection device for detecting connecting a connected peripheral is disclosed herein. The device comprises a peripheral sensor connected to a terminal, a terminal sensor connected to or for connection to a peripheral and a terminal electrical connector connected to the terminal for electrical connection with a peripheral electrical connector connected to a peripheral. The peripheral sensor is positioned to sense the terminal sensor upon connection of the terminal electrical connector with the peripheral electrical connector. The device allows for an electrical connector to be maintained in an unpowered state unless a peripheral is connected thereby reducing or preventing de-plating of the contacts of the electrical connector caused by conductive solution across the contacts as a result of the voltage on the connections. The device also allows for the use of an unpowered peripheral.
