Portable Reader with Limb-Mounted Detection for Hands-Free Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable reader devices require manual initiation of read operations through buttons or voice commands, which are laborious and slow down inventory, collection, and packaging processes, especially when handling multiple product codes, and lack the ability to selectively read desired objects.
Innovation Solution
A portable device with a detection means attached to a limb that generates and transmits command signals based on movement or position information to automatically control the reader's operation, allowing hands-free activation and selective reading of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual button pressing or voice commands are used to initiate read operations, then the reader device can be controlled, but the operation becomes laborious and slows down inventory and goods handling processes
Solution Approach 1:
The reader device automatically initiates read operations by detecting the presence of objects within its reading range, eliminating the need for manual button pressing or voice commands. The system serves itself by autonomously determining when to perform reading based on object detection, thereby increasing productivity without compromising ease of operation.
2Ease of operation
If RF reader device reads all RF signals within reading range without specific activation, then hands-free operation is achieved, but the operator cannot direct the read operation to certain desired goods or objects only
Solution Approach 1:
The system uses detection means to continuously monitor and provide feedback about objects within the reading range. Based on this feedback, the control means intelligently determines which objects should be read, enabling selective reading of desired goods while maintaining hands-free operation. The feedback loop allows the system to adapt to the operator's intentions without manual activation.
3Reliability
If continuous monitoring is maintained during inventory processes to ensure correct operation, then reading accuracy is improved, but the worker feels tired and progress slows down
Solution Approach 1:
The reader device performs continuous monitoring and object detection automatically without requiring the worker to maintain active attention. The system self-manages the monitoring task, ensuring reading accuracy while freeing the worker from mental fatigue. This allows the worker to focus on physical handling tasks rather than continuously monitoring the reading process.

AI summary
A portable device (10, 20) includes at least a control element (14, 24, 34) for receiving command signals and a reader (12, 22, 32). A detection element (18, 28, 38) is connected with the control element (14, 24, 34) and they communicate with each other. Operation of the reader (12, 22, 32) in relation to the object to be identified is controlled through command signals so that at least one of the command signals received by the control element (14, 24, 34) is based on information indicating movement or position received from the detection element (18, 28, 38). The reader (12, 22, 32) is easy to use and quick to operate in its operating environment as no separate actions are required of the user in order to initiate operations.
