Scanner Button Switching via Barcode Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ring-type barcode scanners are limited by having buttons only on one side, making them inconvenient for use with either hand, increasing the device's volume due to rotary scanning heads, and causing accidental activation due to active buttons on both sides.
Innovation Solution
The method involves placing buttons on both sides of the scanner, with a barcode scanning mechanism that switches the active button bit from one side to the other based on preset button switching barcode data, ensuring only one side is active at a time, reducing accidental activations and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If buttons are disposed on both sides of the scanner, then the scanner becomes suitable for both left and right hands, but the buttons are easily touched by other fingers by mistake
Solution Approach 1:
The patent applies dynamics by making the button configuration changeable through software control. The active button bit can be dynamically switched between left and right sides based on scanning results, allowing the system to adapt to different usage scenarios while maintaining only one active button at a time to prevent accidental activation.
Solution Approach 2:
The patent changes the state parameter of the buttons from static (both always active) to dynamic (only one active at a time). By controlling the active button bit through software, the system can switch which side's button is active, thereby preventing accidental activation while maintaining versatility for both hands.
2Adaptability or versatility
If the scanning head is designed to be rotary to meet use requirement for both hands, then the scanner can be used by both hands, but the volume of the entire structure increases
Solution Approach 1:
The patent replaces the mechanical rotary scanning head with a fixed scanning head combined with software-controlled button activation. Instead of physically rotating the scanning head to adapt to different hands, the system uses software to switch which button is active, thereby achieving hand compatibility without increasing the physical volume of the scanning head.
3Loss of energy
If the scanner is in a dormant state to reduce power consumption, then energy consumption is reduced, but the scanner requires button activation to wake up
Solution Approach 1:
The patent applies dynamics by enabling the scanner to switch between dormant and active states based on operational needs. The button activation mechanism allows the scanner to wake up from dormancy when needed, and the ability to switch active buttons provides flexibility in wake-up operation for different hands.
Data Source
AI summary
The present disclosure provides a method for switching scanner buttons, an apparatus, a storage medium, and a scanner. The method comprises: scanning a barcode and obtaining barcode data; determining whether the barcode data matches preset button switching barcode data; in a case that the barcode data matches the button switching barcode data, switching an active button bit for waking up a scanner from a button at the current side to a button at the other side.
