Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcode printers face difficulties in adjusting left-side and right-side end gaps of the upper base, requiring the removal of bolts or opening the upper base, making the process complicated and inconvenient.
Innovation Solution
A horizontal adjustment device comprising a chassis with threaded holes, an adjustment bolt with a screwing engagement section, and an adjustment threaded fastener, allowing for clockwise or counterclockwise rotation to horizontally move the printing-device upper base, thereby adjusting the end gaps of the label paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional label printer structure is used, then the printing device can perform basic printing function, but the adjustment of left-side and right-side end gaps requires removal of bolts or opening the upper base, making the operation complicated and inconvenient
Solution Approach 1:
The patent applies the dynamics principle by making the upper base horizontally movable through a threaded fastening mechanism. The adjustment bolt with external threads engages with the threaded hole in the chassis, allowing the upper base to be positioned at different horizontal locations. This dynamic adjustment capability enables easy modification of end gaps without disassembling the device, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent implements parameter changes by utilizing the threaded engagement between the adjustment bolt and the threaded hole to convert rotational motion into linear displacement. By rotating the adjustment bolt, the horizontal position of the upper base changes, thereby adjusting the end gap parameter. This mechanism provides a simple yet effective way to change the operational parameter (end gap) without complex procedures.
2Ease of operation
If adjustment mechanism is added to enable easy adjustment of end gaps, then the ease of operation is improved, but the device structure becomes more complex
Solution Approach 1:
The adjustment bolt serves multiple functions: it acts as both a fastening element to secure the upper base to the chassis and an adjustment element to control the horizontal position of the upper base. This multi-functionality reduces the need for separate adjustment mechanisms, thereby improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The threaded fastening mechanism is designed to be self-adjusting through simple rotational motion of the adjustment bolt. The user can directly rotate the bolt to achieve the desired end gap adjustment without requiring additional tools or complex procedures. This self-service characteristic simplifies the adjustment process while keeping the mechanism structure relatively simple.
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 fast and easy adjustment of left-side and right-side end gaps of the label paper, simplifying the printing operation by directly engaging the threaded holes and screwing mechanism, improving operational convenience.
Implementation Method 1
The adjustment bolt has an opposite end forming at least one screwing engagement section. The screwing engagement section is in engagement with the threaded hole of the chassis of the barcode printer and another end of the adjustment bolt is rotatably received in the opposite end of the through bore of the printing device.
