Solution Overview

Problem

Users face complexity in controlling multiple electronic devices from a remote location, as each device requires a separate remote controller, which can be cumbersome and requires additional adapter modules, making user handling difficult.

Innovation Solution

A flash light module integrated with a mobile device, such as smartphones or tablets, that incorporates a visible light emitter and an additional non-visible light emitter, like an infrared or UV emitter, to enable remote communication without additional hardware, using the existing camera flash lens for both visible and non-visible light emission, allowing a single device to function as a remote control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a smartphone is equipped with an additional converter comprising an infrared emitter module as a remote controller connected via an external port, then remote control function is added to the smartphone, but device complexity increases and user handling becomes more difficult

Engineering Contradiction:
Improveremote control functionVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the visible light emitter (flashlight) and the infrared emitter into a single integrated module housed together in one housing. This merging eliminates the need for separate external adapter modules while providing both flashlight and remote control functions through a single integrated device, thereby reducing device complexity and improving user handling.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate remote controllers are used to control different electronic devices, then each device can be controlled, but the number of devices increases and user handling becomes cumbersome

Engineering Contradiction:
Improvecontrol capabilityVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The integrated module provides universal functionality by combining both visible light emission (flashlight) and infrared light emission (remote control) in a single device. This multi-functional design allows the smartphone to serve as both a flashlight and a remote control for various electronic devices, eliminating the need for multiple separate devices and reducing user burden.

Inventive Principle:
Principle #6Universality (Multi-functionality)
