Active Mobile Cover with Acoustic Sensor and LED Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phone covers are passive accessories that lack dynamic interaction with the host device, failing to provide enhanced alerts or notifications beyond basic protection and static designs.
Innovation Solution
An active mobile device cover equipped with a processor, illumination or lighting devices, and an acoustic sensor that receives signals from the host device to provide customizable alerts through patterned lighting based on incoming calls, messages, or notifications, allowing for distinct or random lighting sequences and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional passive covers are used, then device protection is provided, but user interaction and alert capability are limited
Solution Approach 1:
The cover transitions from a static passive structure to a dynamic active system with illumination devices that can change lighting patterns, colors, and intensities based on received signals, enabling enhanced user interaction while maintaining protective function
Solution Approach 2:
The cover integrates multiple functions including protection, alert notification through illumination, and user interaction feedback, allowing a single component to serve multiple purposes and reduce the need for separate notification devices
2Reliability
If active illumination devices are added to the cover, then alert capability is enhanced, but energy consumption increases
Solution Approach 1:
The illumination devices operate in periodic cycles, activating only when signals are received from the electronic device, rather than continuously, thereby providing reliable alert notification while significantly reducing overall energy consumption
Solution Approach 2:
The cover utilizes power drawn from the connected electronic device through the connection interface, enabling the illumination function without requiring an independent power source, thus avoiding additional energy burden
3Adaptability or versatility
If multiple illumination patterns are implemented, then notification versatility is improved, but device complexity increases
Solution Approach 1:
The illumination devices can vary multiple parameters including color, intensity, and temporal patterns to create diverse notification types, achieving high versatility through parameter modulation rather than requiring separate physical components for each notification type
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user interaction with the host device by providing superior sensory input and customizable alerts, while also offering protection against drops and scratches.
Implementation Method 1
The acoustic sensor can be configured to receive sound, that can be generated by the host mobile device, for example, and to convert the sound into an analog signal
Implementation Method 2
illumination or lighting devices (e.g., illumination devices, lights, light emitting devices, light emitting diodes (LEDs))
Data Source
AI summary
Systems and methods of providing a mobile device cover are described. In some embodiments, the mobile device cover may include, for example, an acoustic sensor, a processor, and lighting devices. The processor can be operatively coupled to the acoustic sensor and the lighting devices. The acoustic sensor can be configured to receive sound generated by the mobile phone and to convert the sound into an acoustic signal. The processor can be configured to receive the acoustic signal and to determine whether the acoustic signal is similar to one of a plurality of acoustic signals previously stored on the mobile phone cover. Each of the previously stored acoustic signals can be indicative of, for example, a particular caller, a particular message sender, or a particular alert. Based on the acoustic signal determination, the processor is configured to cause lighting of the one or more lighting devices corresponding to the indicated caller, indicated message sender, or indicated alert.
