Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical information reading devices face inconvenience when trying to read specific symbols in a crowded environment, as they require frequent adjustments of the imaging visual field from wide to narrow and back, making the process complicated and time-consuming.
Innovation Solution
An optical information reading device with an aiming module and a trigger switch that allows for precise targeting of specific symbols within a predetermined partial area, eliminating the need to switch between wide and narrow visual fields, and incorporating a reading unit that can read symbols in both aiming and non-aiming states, enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging visual field is set narrow to read only one specific symbol, then the reading precision is improved, but the ease of operation deteriorates due to frequent adjustment requirements
Solution Approach 1:
The patent implements dynamic switching between wide visual field mode and narrow visual field mode based on user needs. The reading range adjustment is made flexible and adaptable rather than fixed, allowing the system to transition between different operational states (wide field for scanning, narrow field for precise reading) to optimize both ease of operation and reading precision in different contexts
Solution Approach 2:
The patent provides preliminary guidance by displaying guidance information that indicates the position and state of the symbol before reading. This preliminary action helps users understand what needs to be read and where to focus, reducing the need for repeated adjustments and improving ease of operation while maintaining reading precision
2Adaptability or versatility
If the imaging visual field is changed frequently between wide and narrow settings, then the adaptability is improved, but the loss of time increases due to repeated setting adjustments
Solution Approach 1:
The patent implements automatic recognition and adaptive adjustment where the system automatically detects the reading situation and adjusts the visual field settings accordingly. The guidance information is automatically generated and displayed based on the current state, eliminating the need for manual setting adjustments and reducing time loss while maintaining high adaptability
Solution Approach 2:
The patent uses feedback mechanisms where the system continuously monitors the reading situation and provides real-time guidance information to the user. This feedback loop allows the system to adapt to changing conditions dynamically without requiring repeated manual interventions, thus reducing time loss while maintaining adaptability

AI summary
An optical information reading device 100 includes an aiming module 60 configured to irradiate aiming light for instructing an imaging area of image data generated by an imaging module, a trigger switch 30 for starting imaging processing by the imaging module, an aiming switch 43B for causing the aiming module 60 to irradiate the aiming light, and a reading unit 81 configured to read information of the symbol. The reading unit 81 is configured to, in an aiming state in which irradiation processing for the aiming light by the aiming module 60 is executed by operation of the aiming switch 43B, detect that the trigger switch 30 is operated and read, based on the image data generated by the imaging processing of the imaging module, information of the symbol included in a predetermined partial area PA corresponding to an irradiation position of the aiming light.
