Adjunct Device for Wireless Object Location via Paging Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices lack an effective method to locate misplaced or lost devices, and there is a need for additional functions and features that can be seamlessly integrated with other wireless devices.
Innovation Solution
A system comprising a handheld wireless communication device and an adjunct device that uses short-range wireless communication to transmit and receive paging signals, allowing users to locate the device through visual and audio alerts, and also enables additional features like home automation and remote control functions via a paired network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless communication devices are used without additional location features, then device simplicity is maintained, but the ability to locate misplaced or lost devices is insufficient
Solution Approach 1:
The patent integrates a location application and adjunct device functionality within the existing wireless communication device framework. The adjunct device couples to the wireless device through a communication port, creating a nested structure where the location functionality is embedded within the broader device ecosystem without requiring a completely separate system
Solution Approach 2:
The wireless communication device is enhanced to serve multiple functions: traditional wireless communication, location tracking of misplaced devices, and remote control of other devices. The location application and adjunct device work together to provide these additional capabilities while maintaining compatibility with existing device architecture
2Adaptability or versatility
If wireless communication devices integrate multiple functions like navigation, messaging, and media playback, then device versatility is improved, but device complexity increases
Solution Approach 1:
The patent extends the multi-functionality concept by enabling the wireless communication device to act as both a location tracker and a remote control. The location application can locate the wireless device itself or other devices, while the adjunct device enables remote control of other wireless devices, creating a universal platform for multiple wireless functions
Solution Approach 2:
The adjunct device serves as an intermediary component that couples between the wireless communication device and external devices. It receives control signals from the wireless device and transmits them to target devices, mediating the interaction without requiring direct integration with each controlled device
