Liquid Ejecting Apparatus Protecting Portion External Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid ejecting apparatuses face challenges in minimizing the impact of external forces on exposed liquid containers, leading to potential disconnection and ink leakage, especially when the ink supply is external to the casing body.
Innovation Solution
A liquid ejecting apparatus design that includes a protecting portion to shield the exposed liquid container from external forces, with a space between the container and the protecting portion to absorb impacts, and a container support mechanism to maintain the liquid container's position, ensuring a stable connection and reducing ink leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid container is exposed to the outside of the casing body for easy access and refilling, then the ease of operation is improved, but the reliability deteriorates due to vulnerability to external forces causing disconnection and leakage
Solution Approach 1:
A protecting portion is provided that surrounds the liquid container to cushion against external forces before they can cause disconnection or leakage. This protective structure absorbs impacts and prevents direct contact between external objects and the liquid container, maintaining connection stability while allowing external access.
Solution Approach 2:
The liquid container is nested within the protecting portion, which itself is integrated with or attached to the casing body. This nested configuration allows the liquid container to be accessible from outside while being protected by the surrounding protecting portion, resolving the contradiction between accessibility and protection.
2Reliability
If a protecting portion is added to shield the liquid container from external forces, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The protecting portion is designed to serve multiple functions: it protects the liquid container from external forces, provides structural support, and can be integrated with the casing body or liquid container structure. This multi-functionality reduces the need for separate protective components, thereby limiting the increase in device complexity.
Solution Approach 2:
The protecting portion is merged with either the casing body or the liquid container structure, rather than being a completely separate component. This integration reduces the number of discrete parts and simplifies the overall structure while still providing the necessary protection.
3Adaptability or versatility
If the liquid container protrudes from the casing body for external connection, then the adaptability is improved, but the object-affected harmful factors increase due to exposure to collisions and external forces
Solution Approach 1:
The protecting portion is positioned to surround the protruding liquid container before external forces can act upon it. This protective barrier cushions against collisions and external forces, allowing the container to maintain its protruding position for external connections while being protected from harmful factors.
Solution Approach 2:
The liquid container protruding from the casing body is nested within the protecting portion, which extends outward to provide coverage. This nested configuration maintains the external accessibility of the liquid container while providing protection against collisions and external forces.
