Printer Busbar Connector for Inkjet Cassette Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printer driving systems face challenges in ensuring precise electrical connections between the inkjet print head cassette and the supporting base, leading to issues with inkjet printing due to frequent misalignment of electrical contacts during assembly and disassembly.
Innovation Solution
A printer driving system utilizing a busbar connector, such as a USB, facilitates quick and convenient positioning and connection of the inkjet print head cassette to the supporting base, maintaining signal integrity and allowing for easy assembly and disassembly without affecting the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical contacts are provided on the circuit board for transmitting electrical signals, then the inkjet print head cassette can receive signals and perform printing procedures, but the electrical contacts must be precisely aligned during assembly which is difficult to achieve and leads to connection failures
Solution Approach 1:
A busbar connector is introduced as an intermediary component between the circuit board and the inkjet print head cassette. The busbar connector includes a busbar with multiple electrical contact points and a connecting structure that facilitates reliable electrical connection without requiring precise manual alignment during assembly, thus resolving the contradiction between connection reliability and assembly ease
2Measurement precision
If the inkjet print head cassette is fixed on the supporting base for precise positioning, then the printing procedure can be performed at the right position, but the frequent replacement of the cassette makes the precise alignment of electrical contacts time-consuming and complex
Solution Approach 1:
The busbar connector is pre-assembled with the circuit board, with the electrical contacts pre-positioned and fixed in the correct alignment. This preliminary action eliminates the need for time-consuming precise alignment during frequent cassette replacements, while still ensuring the inkjet print head cassette is fixed at the correct position for printing
3Reliability
If electrical contacts are made of metal for signal transmission, then the inkjet print head cassette can be driven by the printer, but the misalignment of these contacts during assembly and disassembly causes connection failures and printing issues
Solution Approach 1:
The busbar connector incorporates a flexible or adjustable connecting structure that can dynamically adapt to minor misalignments during assembly. This dynamic capability maintains reliable electrical contact even when perfect alignment is not achieved, reducing assembly complexity while preserving signal transmission reliability
