Unified Voice Output for Multi-Method Commodity Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing commodity identification systems, separate devices used for code symbol recognition and object recognition often emit recognition sounds from different locations, causing discomfort and confusion for operators, especially when multiple methods are employed simultaneously, leading to increased design burdens due to the need for multiple speakers.
Innovation Solution
A reading device configuration that includes a first device with an imaging unit and a voice output unit for emitting a recognition sound, and a second device with a different recognition method, where the first device can input and mix voice data from both units to produce a unified sound output, allowing the recognition sound to be emitted from the same location regardless of the identification method used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for code symbol recognition and object recognition, then each device can independently perform its recognition function, but multiple speakers are required which increases design burden and causes recognition sounds to be emitted from different locations
Solution Approach 1:
The patent combines multiple recognition functions (code symbol recognition and object recognition) into a single integrated reading device. The device includes both a code recognition unit and an object recognition unit within one housing, allowing both recognition types to occur in the same location. This eliminates the need for multiple separate devices and their associated speakers, resolving the contradiction between maintaining reliable recognition functions and reducing design burden.
Solution Approach 2:
The reading device is designed as a multi-functional unit that can perform both code symbol recognition and object recognition. The single device houses multiple recognition units that can operate independently or together, providing universal recognition capability. This multi-functionality allows the device to replace multiple specialized devices while maintaining all necessary recognition functions.
2Ease of operation
If multiple speakers are provided in separate devices, then each device can emit recognition sounds independently, but the operator hears notification sounds from different places causing discomfort and confusion
Solution Approach 1:
The patent merges multiple speaker functions into a single speaker unit within the integrated reading device. Since both code recognition and object recognition occur in the same device, a single speaker can notify the operator for both recognition types. This eliminates the confusion of hearing notifications from different locations while maintaining independent recognition capabilities.
3Use of energy by moving object
If separate devices are used for different recognition methods, then processing load can be distributed, but the number of components increases and design becomes more difficult
Solution Approach 1:
The patent combines multiple recognition processing units into a single integrated device. The reading device includes both code recognition processing and object recognition processing within one unit, reducing the total number of components. The processing load is managed within the integrated device rather than distributed across multiple separate devices, eliminating the need for inter-device communication while maintaining processing capabilities.

AI summary
According to at least one embodiment, a reading device includes a first device and a second device. The first device includes an imaging unit, a first recognition unit configured to recognize a commodity from a captured image of the imaging unit, and a voice output unit configured to emit a voice if the first recognition unit recognizes the commodity. The second device is separate from the first device, and includes a second recognition unit configured to recognize a commodity from the captured image by a method different from that of the first recognition unit and a second voice generation unit configured to output voice data for sounding the voice output unit if the second recognition unit recognizes the commodity. The first device includes a first voice generation unit configured to output voice data for sounding the voice output unit if the first recognition unit recognizes the commodity, an input unit configured to take in voice data output by the second voice generation unit into the first device, and a voice mixer configured to input the voice data taken in by the input unit and the voice data output by the first voice generation unit to the voice output unit.
