Liquid Ejection Head Packaging with Depressurized Bag and Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for liquid ejection heads do not adequately secure the protective member, risking its detachment during transportation and handling, which can lead to damage or soiling of the print chip.
Innovation Solution
A packaging form that includes a detachably attachable protective member, cushioning material on both ends of the liquid ejection head, and a bag member that is sealed in a depressurized state to securely contain the liquid ejection head, protective member, and cushioning material, preventing the protective member from being dislodged during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective member is detachably attached to the liquid ejection head, then the protective member can be removed after use, but the protective member may become unmounted during transportation and handling
Solution Approach 1:
Cushioning material is mounted on the liquid ejection head in advance, and the protective member is attached over it. The cushioning material protruding from the ejection port surface prevents the protective member from becoming unmounted during transportation, while still allowing easy removal after use by simply pulling the protective member in the direction away from the liquid ejection head
2Reliability
If cushioning material is added to secure the protective member, then the protective member remains attached during transport, but the packaging structure becomes more complex
Solution Approach 1:
The cushioning material serves dual functions: it cushions the liquid ejection head during transportation and simultaneously prevents the protective member from becoming unmounted. By combining these two functions into a single component, the packaging structure remains simple while achieving reliable protective member attachment
3Reliability
If the protective member is securely fixed, then it cannot come off during transportation, but it becomes difficult to remove after use
Solution Approach 1:
The cushioning material is positioned specifically at the ejection port surface area, providing localized prevention of protective member detachment. This localized approach ensures secure attachment during transportation while maintaining ease of removal after use, as the protective member can still be pulled off in the direction away from the liquid ejection head
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively secures the protective member to the liquid ejection head, preventing damage and soiling during transportation and handling, while ensuring the protective member remains attached until removal, thus maintaining the integrity of the print chip.
Implementation Method 1
the liquid ejection head, the protective member, and the cushioning material fixed together are contained inside the bag member and sealed in a depressurized state
