Waste Liquid Container Protrusion for Mounting Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste liquid containers for inkjet printers face issues with unnecessary load and mounting failures due to catching in the mounting opening, and potential liquid leaks or pin bending during insertion, especially with position deviations.
Innovation Solution
A waste liquid container design featuring a protrusion that protrudes from the side wall and is positioned lower than the guide portion, allowing smooth insertion and reducing the risk of catching, with a biasing force receiving portion to ensure accurate positioning and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pin is provided in the inner side of the waste liquid container mounting portion for positioning, then positioning accuracy is improved, but the waste liquid tank may be caught in the mounting portion causing unnecessary load and mounting failure
Solution Approach 1:
The guide portion is provided at the front side of the mounting portion to guide the waste liquid tank during insertion before the pin engagement occurs. This preliminary guidance action ensures the tank is correctly positioned and prevents catching in the mounting portion, allowing the pin to engage smoothly with the long hole without causing load or mounting failure.
2Ease of operation
If the pin is loosely inserted into the long hole to allow position deviation, then ease of mounting is improved, but liquid leak from the pin is generated
Solution Approach 1:
The guide portion acts as an intermediary element that facilitates smooth insertion and proper alignment between the pin and long hole. By providing guidance during the mounting process, the guide portion ensures precise engagement without requiring forceful insertion, thereby preventing liquid leak while maintaining ease of mounting.
3Measurement precision
If the pin is forcibly inserted into the long hole to prevent position deviation, then positioning accuracy is improved, but bending of the pin is generated
Solution Approach 1:
The guide portion is provided to guide the waste liquid tank during insertion before the pin engages with the long hole. This preliminary guidance ensures the tank reaches the correct position smoothly, allowing the pin to be inserted without force or deviation, thereby preventing pin bending while maintaining positioning accuracy.
4Device complexity
If the waste liquid tank is inserted from the mounting opening without guide structure, then device complexity is reduced, but the tank is not correctly positioned causing mounting failure
Solution Approach 1:
The mounting portion is segmented into functional components: the guide portion for guidance and the pin for positioning. This segmentation allows each component to perform its specific function efficiently, ensuring correct positioning and reliable mounting without requiring an overly complex overall structure.
