Emergency Communication Assembly with Sequential Calling and Pull-String Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency communication devices are not effectively accessible or user-friendly for physically limited individuals, particularly in emergency situations, as they often require complex operation or are not easily reachable.
Innovation Solution
A housing unit with a communication system that sequentially calls emergency contact numbers and includes a pull string for activation, allowing physically limited users to easily initiate communication with emergency responders, with features like a keypad for programming numbers, a microphone for speaking, and a button for direct 911 access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing emergency communication devices are used, then emergency communication function is provided, but accessibility and ease of operation for physically limited users deteriorates
Solution Approach 1:
The device is segmented into distinct functional components: a pull string mechanism for activation, a communication unit with sequential calling capability, and a power system. This segmentation allows the physically limited user to interact with only the pull string component, simplifying operation while maintaining reliable emergency communication through the automated sequential calling function.
Solution Approach 2:
The communication unit automatically performs sequential calling of emergency contacts without requiring the user to manually dial or select contacts. The system serves itself by automatically attempting to reach emergency contacts in pre-programmed sequence, ensuring reliable communication even when the user has limited physical ability to operate complex interfaces.
2Ease of operation
If complex emergency communication devices are used, then comprehensive emergency communication capability is achieved, but accessibility for physically limited users deteriorates
Solution Approach 1:
The complex communication functions (sequential calling, contact management, emergency protocols) are extracted and automated within the communication unit, leaving only the simple pull string activation mechanism accessible to the user. This extraction allows comprehensive emergency communication capability while maintaining extreme simplicity in user interaction.
Solution Approach 2:
Emergency contact numbers and calling sequences are pre-programmed into the communication unit during setup. This preliminary action eliminates the need for the user to perform complex operations during an emergency, requiring only the simple pull string activation while the pre-configured system handles all communication complexity automatically.
3Ease of operation
If traditional emergency devices are used, then emergency alert function is provided, but ease of activation for physically limited users deteriorates
Solution Approach 1:
The traditional mechanical or electronic switch activation mechanisms are replaced with a simple pull string system that requires minimal physical effort. The pull string directly triggers the communication unit, eliminating complex activation sequences and reducing the time required for physically limited users to activate emergency communication.
Solution Approach 2:
The communication unit is pre-configured with emergency contact information and automated calling sequences before an emergency occurs. This preliminary preparation ensures that upon activation via the simple pull string, the system immediately begins sequential calling without requiring any additional user input or time for configuration, minimizing activation time.

AI summary
An emergency communication assembly includes a housing that is positioned in a pre-determined area such that the housing is accessible to a physically limited user in an emergency. A communication unit is integrated into the housing and the communication unit sequentially calls each of a plurality of emergency contact numbers when the communication unit is actuated until one of the emergency contact numbers answers. In this way the communication unit facilitates the physically limited user to communicate with an individual when the physically limited user is experiencing an emergency. A pull string extends outwardly from the housing and the communication unit is turned on when the pull string is pulled by the physically limited user.
