Barcode Reader Status Lighting for High-Angle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical information reading devices struggle to allow users to grasp the reading status when the top surface is positioned outside their field of view, such as at a higher angle, due to the user's inability to visually recognize the light-emitting unit on the top surface.
Innovation Solution
The device includes a housing with an imaging unit, reading unit, grip portion, push button, and first light-emitting unit on side surfaces, allowing the user to grasp the reading situation through light emission based on the reading unit's status, even when the main surface cannot be visually recognized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the light-emitting unit is provided on the top surface (first main surface), then the device can display reading status information, but the user cannot visually recognize the light-emitting unit when the top surface is positioned outside the user's field of view
Solution Approach 1:
The patent relocates the light-emitting unit from the top surface (first main surface) to the side surface (second main surface or side surface connecting first and second main surfaces). This dimensional relocation allows the light-emitting unit to be visible to users in various orientations, including when the top surface is outside their field of view, while still conveying reading status information effectively.
2Device complexity
If the light-emitting unit is provided on the top surface, then the device structure is simple, but the user cannot grasp the reading situation when viewing from high angles
Solution Approach 1:
The patent repositions the light-emitting unit from the top surface to the side surface of the housing. This spatial reconfiguration ensures that the light-emitting unit remains visible and functional for conveying reading status information regardless of the device's orientation relative to the user, thereby maintaining information delivery without significantly complicating the overall device structure.
3Ease of operation
If the light-emitting unit is provided on the side surface, then the user can visually recognize the light-emitting unit in various postures, but the device requires additional space for light emission components
Solution Approach 1:
The patent places the light-emitting unit on the side surface of the housing, specifically on the second main surface or the side surface connecting the first and second main surfaces. This localized positioning allows the light-emitting unit to be visible to users in various orientations without requiring excessive housing volume, as the light-emitting unit is integrated into the existing housing structure rather than adding significant external dimensions.
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
Enables users to intuitively understand the reading situation by providing tactile feedback and precise aimer light irradiation and imaging, even in postures where the main surface is not visible, enhancing usability and precision.
Implementation Method 1
The first light-emitting unit is provided on at least one of the side surface connecting the first main surface and the second main surface, and the second main surface. The control unit causes the first light-emitting unit to emit light based on the reading situation by the reading unit.

AI summary
The optical information reading device includes an imaging unit, a reading unit, a housing, a grip portion, a push button, a first light-emitting unit, and a control unit. The imaging unit captures images in a predetermined direction, and the reading unit reads information from the images generated by imaging. The housing has the imaging unit and the reading unit arranged inside, and has a first main surface and a second main surface. The first main surface has a display unit. The second main surface is the opposite surface of the first main surface. The grip portion extends from the end on the opposite side of the predetermined direction on the display unit. The push button is pressed in the pressing direction to start imaging. The first light-emitting unit is provided on at least one of the side surfaces and the second main surface.
