Sensorized Connector Engagement for Incomplete Mating Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical and electrical connectors often result in incomplete or broken connections due to mechanical weaknesses, leading to reduced system performance or failure, as users may not detect these issues, especially under stress or fatigue.
Innovation Solution
A connector assembly that includes a receptacle with an integrated sensor, such as an electro-optical sensor or pressure sensor, which generates an electrical signal when a mating connector is properly aligned and seated, ensuring secure connections and detecting any misalignment or disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a click-to-lock configuration is used to prevent disconnection, then connection reliability is improved, but the ability to detect incomplete connections is worsened because users lack feedback
Solution Approach 1:
The patent applies feedback by implementing a sensor that detects the position of the mating connector and provides information about connection status. The sensor monitors whether the connector is properly seated and connected, giving real-time feedback about the connection state that was previously unavailable to users.
Solution Approach 2:
The patent replaces the purely mechanical click-to-lock system with an enhanced system that incorporates electronic sensing. The mechanical engagement is supplemented by electronic sensors that detect connection status, transitioning from a purely mechanical detection method to an electromechanical system.
2Duration of action of stationary object
If mechanical connections are made stronger to prevent breakage, then connection durability is improved, but device complexity increases due to additional sensor components
Solution Approach 1:
The patent applies multi-functionality by designing a sensor system that serves multiple purposes: detecting connection status, monitoring connector position, and potentially detecting misalignment. This single sensing mechanism addresses multiple connection quality aspects rather than requiring separate mechanisms for each function.
Solution Approach 2:
The connector assembly performs self-monitoring through the integrated sensor that automatically detects connection status without requiring external inspection or additional complex monitoring systems. The sensor enables the connector to self-verify its own connection state.

Function Achieved in This Case
The sensor-based connector assembly ensures reliable and secure connections by providing tactile feedback and detecting alignment, thereby preventing system failures and maintaining performance even under stress or fatigue.
Implementation Method 1
an electrical switch mounted to the receptacle. When the mating connector is received at a predetermined position within the receptacle, the electrical switch may either generate or stop generating an electrical signal

AI summary
A connector assembly includes an adapter (2250), a housing device (2211), a ferrule assembly, and a sensor (2230). The housing device is received by the adapter and has a bore, a front end, and a rear end opposite the front end. A ferrule (2117B) of the ferrule assembly is within the bore of the housing device and has a mating end extending beyond the front end of the housing device. The sensor is mounted on the rear end of the housing device, the rear end of the ferrule assembly, or on the adapter confronting and spaced apart from the housing device or the ferrule assembly. The sensor is configured for detecting a force applied by the housing device or the ferrule assembly, respectively. An electrical characteristic of the sensor changes to indicate a predetermined force has been applied by the housing device or the ferrule assembly, respectively.
