Printer Paper Tray with Release Mechanism for Breakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing medium accommodating apparatuses face challenges in efficiently managing the discharge of printing media from desktop printers without stands, leading to potential surface scratches, jamming, and inconvenience due to the need for manual handling, and risk of breakage from user contact.
Innovation Solution
A printing medium accommodating apparatus with a receiving member and a holding member that can transition between connected and separated states, attached to the printer using attachment units, allowing for a U-shaped cloth to collect discharged media and prevent contact-induced breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accommodating portion is disposed outside the desk end portion to allow discharged medium to be received, then the printing medium can be collected, but the user may come into contact with the accommodating portion causing breakage due to load
Solution Approach 1:
The holding member is designed to be movable between a holding state (connected to attachment unit) and a released state (separated from attachment unit). When user contact is detected or anticipated, the holding member automatically transitions to the released state, allowing the accommodating portion to detach and fall to the ground, thus preventing breakage while maintaining ease of operation during normal use
Solution Approach 2:
The system prepares for potential user contact by pre-configuring the holding member to be releasable. Before actual contact occurs, the mechanism is already in place to quickly release the accommodating portion, preventing the harmful effect of breakage while maintaining the beneficial function of medium collection
2Productivity
If a fixed accommodating portion is used to receive discharged medium, then medium collection is effective, but the setting position is limited to where the stand can be placed
Solution Approach 1:
The holding member's ability to move between connected and separated states enables the accommodating portion to be dynamically positioned. During normal operation, it is held in the optimal collection position for productivity. When relocation is needed, it can be released and repositioned, providing adaptability to different desk configurations and user preferences
3Stability of the object's composition
If the holding member is always connected to the attachment unit, then the accommodating portion remains stable, but it cannot separate upon user contact preventing breakage
Solution Approach 1:
The holding member is designed with controlled instability - stable during normal operation when connected to the attachment unit for reliable medium collection, but capable of becoming unstable and releasing when user contact is detected. This dynamic behavior resolves the contradiction by adapting the stability level based on operational conditions
Solution Approach 2:
The holding member automatically detects user contact through the load sensor and self-releases from the attachment unit without requiring external intervention. This self-service mechanism maintains stability during normal use while automatically providing protection against breakage when needed

AI summary
In a printing medium accommodating apparatus, a printing medium discharged from a discharge port of a printing apparatus is stacked. The printing medium accommodating apparatus includes: a receiving member configured to receive a printing medium discharged from the discharge port; and a holding member having a holding portion configured to hold one end of the receiving member, the holding member being capable of being connected with a first attachment unit attached to the printing apparatus, the holding member being configured to be capable of transitioning from a first state where the holding member is connected with the first attachment unit to a second state where the holding member is separated from the first attachment unit.
