Thermal Print Head Ribbon Fold for Compact Pivoting Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermal printing systems face challenges in maintaining compactness and cost-effectiveness due to the need for flexible electrical connections that require significant space for pivoting, leading to potential malfunctions and increased width, while existing configurations either obstruct the paper path or necessitate long cables, compromising system efficiency and ease of maintenance.
Innovation Solution
A thermal printing system with a flexible electrical connection ribbon that folds 180° between planar portions, allowing pivoting parallel to the drive axis, combined with a detection mechanism and locking mechanism to ensure proper alignment and secure electrical connection, reducing the required space and preventing cable-related issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible electrical connection ribbon is used to enable pivoting of the movable frame, then electrical connectivity is maintained during movement, but the system width increases and significant space is required for pivoting operations
Solution Approach 1:
The patent positions the flexible electrical connection ribbon in the thickness direction (Z-axis) of the printing system rather than extending it in the width direction (Y-axis). The ribbon is folded back on itself within the fixed frame's thickness, allowing the movable frame to pivot without increasing the system's external width. This dimensional repositioning resolves the contradiction by maintaining electrical connectivity while avoiding width increase.
2Ease of operation
If the movable frame is positioned in the open position for maintenance, then access to the paper strip passage is enabled, but the electrical connection interface must be repositioned and risk of disconnection increases
Solution Approach 1:
The patent employs a flexible electrical connection ribbon that can dynamically adapt its configuration during pivoting operations. The ribbon is designed with sufficient flexibility to accommodate the movable frame's movement from closed to open position while maintaining continuous electrical contact. This dynamic flexibility allows maintenance access without compromising connection stability, as the ribbon naturally follows the movement rather than requiring manual repositioning.
3Reliability
If conventional electrical cables are used for connection, then electrical signals can be transmitted, but the cables require significant length and space for movement, increasing device complexity
Solution Approach 1:
The patent implements a nested configuration where the flexible electrical connection ribbon is folded back on itself and positioned within the thickness of the fixed frame. The ribbon connects the movable frame to the fixed frame by nesting within the existing structural space rather than extending outward. This nesting approach eliminates the need for long external cables and simplifies cable management while maintaining signal transmission capability.
