Rotatable Barcode Scanner Assembly with 360-Degree Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcode scanners have limited operational flexibility due to a fixed scan head, restricting user movement and comfort during scanning, making it difficult for users to rapidly and smoothly scan goods in various environments.
Innovation Solution
A rotatable assembly comprising a rotatable collar, rotatable stopper, and fixed stopper, allowing 360-degree rotation through opposing sliders and slide grooves, integrated with an optical scanner to enable 360-degree scanning and additional tilting capabilities, enhancing user flexibility and scanning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the scan head is fixed to the base of the barcode scanner, then the structure is simple and stable, but the operational flexibility and user comfort are limited
Solution Approach 1:
The scan head is transformed from a fixed structure to a dynamic rotatable structure. The rotatable collar with slide grooves and sliders enables the scan head to rotate 360 degrees horizontally and tilt vertically, allowing users to adjust the scanning angle according to different operational needs while maintaining structural integrity through the guide groove mechanisms.
2Adaptability or versatility
If the scan head is made rotatable to improve operational flexibility, then user comfort and scanning capability are enhanced, but the device complexity increases
Solution Approach 1:
The rotatable mechanism is segmented into independent functional components: the rotatable collar for horizontal rotation, the slide grooves for angular limitation, and the sliders for movement control. This segmentation allows each component to perform its specific function while keeping the overall structure manageable and maintainable.
Solution Approach 2:
The slide grooves act as intermediary elements between the rotatable collar and the base structure. They provide a guided path for the collar's rotation, enabling smooth movement while constraining the rotation within safe angular limits to prevent damage to the scanning device.
3Area of stationary object
If the rotatable collar rotates 360 degrees, then the scanning coverage is maximized, but the risk of damage from excessive rotation is increased
Solution Approach 1:
The guide grooves in the rotatable collar预先 (in advance) prevent excessive rotation by providing physical constraints. The grooves are designed with specific angular limits that stop the collar from rotating beyond safe boundaries, thereby protecting the scanning device from damage while still allowing full 360-degree operational coverage.

AI summary
A rotatable assembly includes a rotatable collar, a rotatable stopper and a fixed stopper. The rotatable collar has a first slide groove. The rotatable stopper includes a first slider and a second slider which are opposite to each other. The first slider slidably is installed in the first slide groove. The rotatable collar is rotatable relative to the rotatable stopper within a first rotatable angle by the first slider. The fixed stopper has a second slide groove. The second slider is slidably installed in the second slide groove. The rotatable stopper is rotatable relative to the fixed stopper within a second rotatable angle by the second slider. A sum of the first rotatable angle and the second rotatable angle is 360 degrees.
