Developer Storage Container Substrate Removal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The classification of used image drum units is hindered by the difficulty in removing substrate members from tag storage portions, leading to time-consuming classification processes.
Innovation Solution
A developer storage container with a substrate support structure featuring a container wall, first and second support portions, and a lid portion with protrusions that allow for easy access and removal of the substrate member, facilitating simplified classification work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the substrate member is securely stored in the tag storage portion, then the substrate member is firmly held, but it becomes difficult to remove the substrate member for classification
Solution Approach 1:
The support structure is divided into a first support portion (fixed to container wall) and a second support portion (movable relative to first support portion). This segmentation allows the substrate member to be securely held during storage while enabling easy removal by applying force to the movable second support portion, which releases the substrate member without requiring forceful extraction from a fully fixed structure.
2Reliability
If the tag storage portion is designed for secure storage, then the substrate member is protected, but classification work takes more time
Solution Approach 1:
The second support portion is designed to be movable relative to the first support portion, transforming the storage structure from a static, fixed configuration to a dynamic one. During normal storage, the structure provides reliable protection. During classification, the movable portion can be easily shifted or removed, allowing rapid substrate member extraction without compromising the protective function when needed.
3Strength
If the substrate member is tightly fixed in the storage portion, then secure storage is achieved, but removal requires excessive force and time
Solution Approach 1:
By dividing the support structure into fixed and movable portions, the invention creates a controlled weakness point at the interface between the two support portions. This allows the substrate member to experience strong holding force during storage while enabling time-efficient removal by simply disengaging the movable second support portion, avoiding the need to overcome excessive fixed connection strength.

AI summary
A developer storage container includes a container wall, a substrate member having first and second surfaces, and a storage portion provided on the container wall and storing the substrate member. The storage portion includes an outer surrounding wall provided on the container wall, a first support portion disposed inside the outer surrounding wall and supporting the first surface of the substrate member, and a second support portion disposed inside the outer surrounding wall and connected to the container wall. The second support portion supports the first surface of the substrate member. A lid portion is fixed to the outer surrounding wall and has an opening through which the substrate member is exposed. The lid portion contacts the second surface of the substrate member. The lid portion includes first and second protrusions protruding in a second direction perpendicular to a first direction from the substrate member to the container wall. A distance between the first and second protrusions in the second direction is shorter than a length of the substrate member in the second direction. The outer surrounding wall has a through-hole disposed so as to face the second support portion.
