Caller ID-Based Call Handling for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals, especially the elderly or those with disabilities, often cannot answer their phones due to physical limitations, leading to missed calls which may be inconvenient or result in unnecessary emergency services being contacted.
Innovation Solution
A call handling system integrated into a voice communication device that automatically answers calls, plays custom messages, or forwards calls based on caller ID information, allowing for programmable user settings to manage incoming calls without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person is bedridden or unable to reach the phone, then the person cannot answer incoming calls, but this leads to missed calls and potential unnecessary emergency responses
Solution Approach 1:
The system enables the telephone to automatically answer calls without requiring physical intervention from the user. The auto-answer function detects incoming calls and automatically lifts the handset or activates speakerphone, allowing the user to receive and respond to calls even when bedridden or unable to reach the phone.
Solution Approach 2:
The patent introduces an intermediary system consisting of a control unit and sensor that mediates between the incoming call and the user. The sensor detects the user's presence or state, and the control unit automatically manages call answering based on detected conditions, eliminating the need for direct physical interaction with the phone.
2Reliability
If the phone automatically answers all calls, then call reception is reliable, but the user cannot distinguish between urgent and non-urgent calls
Solution Approach 1:
The system incorporates feedback mechanisms where the user can indicate their state or call priority through simple inputs. The control unit uses this feedback to adjust auto-answer behavior, playing prerecorded messages for non-urgent calls while maintaining reliable connection for urgent calls based on user preferences and detected conditions.
Solution Approach 2:
The patent applies different handling qualities to different calls based on user-defined criteria. Certain calls receive automatic answering with prerecorded messages, while other calls are handled differently based on their nature, time of day, or user state, allowing differentiated treatment without manual intervention for each call.
3Adaptability or versatility
If multiple speakerphones are placed around the house, then the caller can listen to events throughout the facility, but the device complexity increases
Solution Approach 1:
The patent makes the primary telephone device multi-functional by integrating speakerphone capability with automatic call handling and remote listening features. A single device performs multiple functions including answering calls, playing prerecorded messages, and providing ambient sound monitoring, eliminating the need for multiple separate speakerphone devices throughout the house.
