Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid ejecting heads require different covers due to variations in component height, number, or arrangement, leading to complex management and increased costs and environmental load.
Innovation Solution
A liquid ejecting head with a cover that is expandable and contractible in the height direction, accommodating various component configurations without the need for multiple cover types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different covers are prepared for different component heights and configurations, then the liquid ejecting head can accommodate various specifications, but the management becomes complicated and cost increases
Solution Approach 1:
The cover is designed with movable portions that can dynamically adjust their position to accommodate different component heights. The cover includes a first member and a second member that can move relative to each other in the height direction, allowing the same cover to adapt to various specifications without requiring multiple fixed cover types.
Solution Approach 2:
A single cover design serves multiple functions by accommodating different numbers and arrangements of components through its movable structure. The cover can accommodate one or both the flow path member and relay substrate by adjusting the position of its movable portions, eliminating the need for separate covers for different configurations.
2Adaptability or versatility
If different covers are prepared for different component heights and configurations, then the liquid ejecting head can accommodate various specifications, but the cost increases
Solution Approach 1:
The cover is designed as a universal component that can accommodate multiple different component configurations through its movable structure. By using a single cover design with adjustable portions, the manufacturing cost is reduced compared to producing multiple specialized covers for different specifications.
Solution Approach 2:
The movable portions of the cover allow it to adapt to different component heights without requiring multiple fixed designs. This dynamic structure eliminates the need for expensive multi-type cover production while maintaining the ability to accommodate various liquid ejecting head specifications.
3Adaptability or versatility
If different covers are prepared for different component heights and configurations, then the liquid ejecting head can accommodate various specifications, but the environmental load increases
Solution Approach 1:
The cover is designed as a universal component that eliminates the need for multiple specialized covers. By using a single cover type with movable portions that can accommodate different configurations, the amount of material waste and environmental load associated with producing and disposing of multiple cover types is significantly reduced.
Solution Approach 2:
The dynamic movable structure of the cover allows it to adapt to different component arrangements without requiring separate covers for each specification. This reduces the overall material consumption and environmental impact compared to producing multiple fixed cover designs for different liquid ejecting head configurations.
