Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inkjet printing apparatuses face issues with data loss from semiconductor storage means due to rough operation or play between the carriage and ink cartridge, leading to disabled recording operations.
Innovation Solution
The design incorporates a contact mechanism with elastic members and strategically positioned electrodes on the ink cartridge and print head, ensuring secure data transfer and preventing data loss during cartridge installation and operation, using elastic members with high friction coefficients and conductive, transformable pawls to maintain contact and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If semiconductor storage means and electrodes are arranged on the ink cartridge for data storage and reading, then recording operation control is enabled, but data loss occurs due to rough operation or play between carriage and ink cartridge
Solution Approach 1:
The patent applies beforehand cushioning by providing elastic members that maintain continuous contact between the ink cartridge and carriage throughout operation. The elastic members are pre-positioned to compensate for any play or movement, ensuring that semiconductor storage means and electrodes remain in reliable contact without data loss, even during rough operation or carriage movement.
2Ease of operation
If electrodes are positioned to contact semiconductor storage means during ink cartridge installation, then data reading is enabled, but contact failure occurs due to rough operation or play between components
Solution Approach 1:
The patent applies dynamics by using elastic members instead of rigid contact structures. The elastic members can dynamically adjust their position and pressure in response to carriage movement, rough operation, or installation variations, maintaining reliable electrical contact between electrodes and semiconductor storage means throughout the operating range without requiring precise positioning.
3Device complexity
If simple electrode arrangement is used on ink cartridge, then device complexity is reduced, but data transfer reliability deteriorates due to play between carriage and ink cartridge
Solution Approach 1:
The patent introduces elastic members as intermediary elements between the simple electrode arrangement on the ink cartridge and the carriage. These elastic members act as mediators that transmit and maintain electrical contact despite play or movement between components, enabling reliable data transfer without requiring complex electrode positioning or additional structural complexity.
