Current smartphone and media player devices are limited by slower processing speed and limited imaging capabilities, making them unsuitable for industrial and commercial applications that require high-speed image handling and processing of barcodes and other symbologies.
Innovation Solution
A water/weather-resistant module is designed to be mounted on a handheld device, featuring an imager with optics and image processing capabilities, which enhances image acquisition and processing speed, and includes user interface elements like indicator lights and alarms for successful or unsuccessful ID reading, with a subframe adaptable to different device models and charging via induction coils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smartphone and media player devices are used for ID reading applications, then portability and native communication functions are improved, but processing speed and imaging capabilities deteriorate
Solution Approach 1:
The system is divided into two functional segments: a portable mobile device (smartphone/media player) that provides communication and user interface functions, and a separate imager module that provides high-speed image acquisition and processing capabilities. This segmentation allows each component to be optimized for its specific function while working together as an integrated system.
Solution Approach 2:
The mobile device acts as an intermediary between the imager module and the data processing system. It receives image data from the imager module via wired or wireless communication, processes the data through vision system applications, and communicates results to external systems, thereby bridging the capabilities of portable devices with industrial-grade imaging requirements.

3Adaptability or versatility
If a universal main body/frame is used to accommodate different devices, then device compatibility is improved, but manufacturing complexity increases
Solution Approach 1:
The main body/frame is designed with universal mounting features and standardized interfaces that can accommodate multiple models and makes of mobile devices. The imager module can be mounted in various orientations and positions within the same frame structure, allowing a single design to serve multiple device types without requiring custom manufacturing for each device model.
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
The module enables high-speed image data handling and processing, supporting industrial applications by providing a robust and versatile tool for ID decoding and vision systems, while maintaining the device's native functions and accommodating various device form factors.
Implementation Method 1
The charging circuit can be operatively connected to an induction coil mounted on the main body, and the external charger can include a corresponding induction coil that selectively transmits energy to the induction coil mounted on the main body
Data Source
AI summary
This invention provides a module for a handheld device. The module includes an imager with optics and image acquisition/processing processors that provide high speed acquisition and handling of acquired image data—such as IDs. The acquired image data is processed by the device processor using a module application that resides within the device. The module includes indicators and/or alarms that can indicate success in reading an ID. A subframe removably mounts within the module's main body/frame and carries the device. The subframe can vary to accommodate different devices within a single main body/frame geometry. The main body/frame includes appropriate structures (ports) to enable optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The main body/frame can also house a battery and charging assembly that supplies power to the device and allows charging through-for example and inductive charging unit.
