Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcode printers face challenges in achieving precise pressure adjustment and tight engagement between the printing head and label sheets of varying widths, leading to potential unbalanced pressure and inclination issues, which affect printing quality and increase manufacturing costs due to the need for different pressure regulation mechanisms for different label widths.
Innovation Solution
A label sheet positioning device with a pressure regulation seat featuring two pressure adjusting knobs and a universal adjusting knob for fine adjustment in both pressure and inclination direction, allowing for universal fine adjustment of the printing head holder to ensure tight engagement with label sheets of various widths, reducing the need for multiple pressure mechanisms and lowering manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional pressure adjusting knobs are used for label sheets of standard width, then proper pressure adjustment can be achieved, but the system cannot ensure tight engagement for label sheets of reduced width
Solution Approach 1:
The patent applies universality by designing a pressure regulation mechanism that can accommodate both standard width and reduced width label sheets using the same basic structure. The mechanism achieves this through adjustable components including a movable pressing piece that can be positioned at different locations along the label sheet width, allowing a single device to perform multiple functions across different label sizes without requiring separate mechanisms for each width.
Solution Approach 2:
The patent implements dynamics by making the pressing piece movable rather than fixed. The pressing piece can be adjusted along the label sheet width and tilted at different angles to match the inclination of various label sheet sizes. This dynamic adjustment capability allows the system to adapt to different label configurations, maintaining proper engagement and pressure distribution whether the label is standard width or reduced width.
2Manufacturing precision
If different pressure regulation mechanisms are designed for different label sheet widths, then proper engagement can be ensured for each width, but manufacturing costs increase
Solution Approach 1:
The patent reduces manufacturing costs by creating a universal pressure regulation mechanism that serves multiple label sheet widths. Instead of producing separate mechanisms for different label sizes, the invention uses a single adjustable mechanism with a movable pressing piece that can be repositioned and reoriented to accommodate various label widths, thereby eliminating the need for multiple specialized components and reducing overall manufacturing complexity and cost.
Solution Approach 2:
The patent applies segmentation by dividing the pressure regulation function into independent adjustable components. The pressing piece is separated from the fixed structure and can be independently positioned and angled. This modular approach allows the same basic mechanism to be used across different label widths without requiring complete redesign, thus lowering manufacturing costs while maintaining adaptability.
3Device complexity
If conventional pressure adjustment mechanisms are used, then simple structure is maintained, but inclination between printing head and label sheet cannot be corrected
Solution Approach 1:
The patent introduces dynamic adjustment capability with minimal added complexity. The pressing piece is made movable and tiltable, allowing it to follow the inclination of the label sheet. This dynamic element is coupled to the existing pressure adjustment knobs through a linkage mechanism that translates rotational knob movement into linear and angular adjustments of the pressing piece, achieving inclination correction without substantially increasing overall device complexity.
Solution Approach 2:
The patent uses an intermediary linkage mechanism that connects the simple rotary pressure adjustment knobs to the movable pressing piece. This intermediary translates the simple rotational motion of the knobs into the complex combined linear and angular motion required to position and orient the pressing piece correctly, thereby achieving precise engagement and inclination correction while maintaining the simplicity of the user interface.

AI summary
A label sheet positioning device is provided for a barcode printer, including a pressure regulation seat having two pressure adjusting knobs and at least one universal adjusting knob mounted to a top thereof. The pressure adjusting knobs serve to adjust pressure for positioning in the upward-downward direction of a label sheet of the barcode printer. The universal adjusting knob functions to realize fine adjustment of pressure for positioning in a universal adjustable manner that the pressure regulation seat applies to the label sheet. At least one universal adjusting mechanism is coupled to bottom of the pressure regulation seat for effecting adjustment of inclination direction by the universal adjustment realized by the universal adjusting knob. At least one printing head holder is coupled to a front portion of the universal adjusting mechanism and has a bottom coupled to a printing head, whereby the printing head holder is subjected to adjustment of pressure in upward-onward direction by the pressure adjusting knobs of the pressure regulation seat and is also subjected to fine adjustment of inclination direction by the adjustment that the universal adjusting knob applies to the universal adjusting mechanism to effect universal fine adjustment for the printing head holder and the printing head in order to ensure tight engagement of the printing head with respect to the label sheet of the barcode printer. Thus, a label sheet positioning device featuring universal fine adjustment of inclination direction is provided.
