Ant-Loss Cell Phone Case with Segmented Transmitter and Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell phone case designs lack an integrated anti-loss system that alerts the user when the phone is beyond a predetermined distance, and previous solutions are either complex or inefficient.
Innovation Solution
A cell phone case with an integral transmitter device and a detachable receiver device that emit alerts when the phone is farther than a predetermined distance, using a transmitter assembly attached to the case and a receiver assembly attachable to the user's body, powered by separate batteries and configured for audible or vibration alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an anti-loss system is integrated into the cell phone case, then the reliability of preventing phone loss is improved, but the device complexity increases
Solution Approach 1:
The anti-loss system is divided into two separate components: a transmitter device integrated into the cell phone case and a receiver device that can be attached to the user's body or belongings. This segmentation allows the anti-loss functionality to be added without significantly complicating the cell phone case design, as the complex receiver functions are housed in a separate unit.
Solution Approach 2:
The receiver device is designed to be attachable to various user belongings (clothing, bags, keys) and provides multiple functions including distance monitoring, alert generation, and potential integration with other user items. This multi-functionality justifies the added complexity by providing versatile utility beyond simple phone location tracking.
2Reliability
If a transmitter device and receiver device are added to the cell phone case, then the anti-loss functionality is improved, but the weight of the cell phone case increases
Solution Approach 1:
By separating the transmitter (in the case) from the receiver (on user belongings), the weight of the case is minimized while still providing functional anti-loss protection. The heavier receiver components are placed on items the user already carries.
Solution Approach 2:
The transmitter device in the case is designed as a simpler, potentially less expensive component with shorter battery life expectations, while the receiver device that the user carries separately can be more robust and longer-lasting, optimizing the weight distribution.
3Reliability
If separate battery power sources are used for transmitter and receiver, then the operational independence and reliability are improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The system uses separate battery power sources for the transmitter and receiver devices, which segments the power supply requirements. This allows each component to be manufactured and tested independently, potentially reducing overall manufacturing complexity despite the additional component.
Solution Approach 2:
Each device (transmitter and receiver) is self-powered with its own battery, allowing them to operate independently without requiring external power sources or complex power management systems. This self-service approach simplifies the overall power architecture.

AI summary
An ant-loss cell phone case including a transmitter assembly and a receiver assembly. The transmitter assembly includes a transmitter device coupled in a rare compartment of a cell phone case. The transmitter assembly is protected by a compartment cover which includes inside thereof a battery to power the transmitter device allowing to broadcast a signal. The receiver assembly includes a receiver device associated to the transmitter device, wherein the receiver assembly is attachable to the user's body or belonging by means of a swivel snap hook and will emit an alert if the transmitter assembly and the receiver assembly are farther than a predetermined distance therebetween.
