Liquid Jet Head Circuit Board Markings for Reliable Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid jet recording apparatuses face challenges in enhancing reliability while preventing a rise in cost, particularly in ensuring proper coupling between circuit boards in liquid jet heads, which can lead to abnormal insertion states and reduced design freedom.
Innovation Solution
The implementation of a circuit board configuration with marking portions on both the first and second circuit boards to visually confirm the coupling state, using existing patterning or reinforcing elements, thereby avoiding additional processing costs and ensuring reliable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If marking portions are added to visually confirm coupling state, then reliability is improved, but manufacturing cost increases
Solution Approach 1:
The marking portions are merged with existing structural elements of the circuit boards. The first marking portion utilizes the connector's existing structure, while the second marking portion utilizes the terminal section's existing structure. This merging approach allows visual confirmation of coupling state without adding separate dedicated marking components, thereby improving reliability while avoiding increased manufacturing costs.
2Reliability
If complex coupling confirmation methods are used, then reliability is improved, but device complexity increases
Solution Approach 1:
The circuit boards themselves provide the marking portions needed for coupling confirmation. The connector and terminal section, which are essential components for electrical connection, also serve as visual indicators of proper coupling. This self-service approach eliminates the need for separate confirmation mechanisms, sensors, or additional detection systems, thereby maintaining simplicity while improving reliability.
