Franking Machine Non-Security Housing for Ink Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing franking machines face high conversion and maintenance costs due to the need to open the security housing for ink-related component access and replacement, which complicates color changes and resale, especially in rental scenarios where ink contamination and cleaning are time-consuming and inefficient.
Innovation Solution
Designating non-security areas for ink-contaminated components, incorporating a modular ink collection container, and using a multifunction pen to move the printing carriage without power, allowing for assembly and maintenance without opening the security housing, including a cleaning and sealing station with removable modules for inkjet printheads and an ink absorber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the security housing is opened to access ink-related components, then maintenance and color changes can be performed, but maintenance time and costs increase significantly
Solution Approach 1:
The housing is divided into a security housing (enclosing the printing mechanism) and a non-security housing (containing ink-related components). This segmentation allows the ink reservoir, ink absorber, and cleaning station to be accessed and maintained independently without opening the security housing, thereby reducing maintenance time while preserving security.
2Ease of repair
If the security housing is opened for maintenance, then ink components can be replaced, but contamination risks and cleaning requirements increase
Solution Approach 1:
By separating ink-related components into a non-security housing section, the patent isolates potential ink contamination from the secure printing mechanism. Maintenance personnel can replace ink reservoirs and absorbers without compromising the sealed environment of the printing mechanism, thereby reducing contamination risks.
Solution Approach 2:
The non-security housing acts as an intermediary zone between the external environment and the secure printing mechanism. This intermediate structure allows ink components to be accessed and replaced while preventing direct exposure of the printing mechanism to ink-related contaminants.
3Ease of operation
If ink-related components are accessible without opening security housing, then maintenance is simplified, but device structure becomes more complex
Solution Approach 1:
The housing is segmented into security and non-security sections, with the non-security section providing easy access to ink components through a simple opening or removable panel. This segmentation adds structural complexity but enables simplified maintenance operations without requiring security housing to be opened.
Solution Approach 2:
The non-security housing serves multiple functions: it contains ink-related components, provides access for maintenance, and acts as a barrier to protect the security housing from contamination. This multi-functionality justifies the additional structural complexity by consolidating multiple requirements into a single design element.
4Adaptability or versatility
If the franking machine is converted to a different country, then resale value increases, but cleaning and conversion costs are high
Solution Approach 1:
The segmentation of ink components into a separate non-security housing allows for rapid removal and replacement of ink reservoirs and absorbers during country conversion. This eliminates the need for extensive cleaning of the security housing and printing mechanism, thereby reducing conversion time and enabling faster adaptation to different postal authorities' color requirements.

AI summary
The franking machine (1) has an ink printing unit to which flat material is pressed by a pressing unit. The pressing unit comprises separable and interchangeable box-shaped component (6). The security housing comprises upper casing (2) and lower casing (5) for enclosing the ink printing unit and control unit. The lower casing is provided at the front side and bottom side of the franking machine so that all the ink-polluted components are arranged in the non-secure areas of the franking machine.
