Rotatable Optical Housing for Adjustable Code Scanner Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional code scanners lack the ability for users to choose the scanning direction, making it inconvenient when the scanning direction does not match the position of the code, requiring users to switch between different scanners.
Innovation Solution
An optical device with a housing, lens module, and fixing member that can be detachably affixed to a scanner, allowing the light to be directed between 5 and 175 degrees, enabling flexible adjustment of the scanning direction by pivoting the housing relative to the fixing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional code scanner is used with a fixed scanning direction, then the device structure is simple, but the user cannot choose the scanning direction when the code position does not match the scanning direction
Solution Approach 1:
The patent applies the dynamics principle by making the housing rotatable relative to the scanner body through a fixing member with a guiding slot. The housing can be rotated to different angles (between 5 and 175 degrees) to change the scanning direction, transforming a static fixed-direction scanner into a dynamic multi-directional scanner. This resolves the contradiction by enabling scanning direction adaptability while maintaining relatively simple device structure through a single rotatable component.
2Adaptability or versatility
If multiple code scanners with different scanning directions are used to accommodate different code positions, then the scanning direction coverage is complete, but the device quantity and system complexity increase
Solution Approach 1:
The patent applies the universality principle by designing a single scanner that can perform multiple scanning directions through the rotatable housing. Instead of requiring multiple specialized scanners for different directions, one universal scanner with adjustable housing can cover all scanning needs. The lens module and optical path remain the same, but the housing rotation enables the same device to scan in various directions, reducing the number of devices needed from multiple to one.
3Ease of operation
If the housing is made rotatable relative to the scanner, then the scanning direction can be adjusted flexibly, but the device structure becomes more complex
Solution Approach 1:
The patent applies the segmentation principle by separating the housing from the scanner body and connecting them through a fixing member with a guiding slot. This segmentation allows the housing to be independently rotated and positioned at different angles while keeping the scanner body stationary. The guiding slot provides a simple mechanical constraint that enables rotation without requiring complex motors or actuators, thus achieving operational flexibility with minimal structural complexity.
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 flexible adjustment of the scanning direction, allowing the scanner to accommodate codes positioned between objects without the need for multiple scanners, enhancing user convenience and scanning efficiency.
Implementation Method 1
The light provided by the scanner enters the housing through the first opening, and the lens module guides the light to leave the housing through the second opening
Implementation Method 2
the light falling on the scanned object can be reflected by the scanned object and enter the housing through the second opening, and the lens module guides the light to leave the housing from the first opening
