Segmented Cap Design for Developer Container Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional powder containers for image forming apparatuses face challenges in efficiently opening and closing the discharge port, affecting the operability and reliability of toner supply during the assembly and usage processes.
Innovation Solution
A cap with a first and second attaching member, detachably assembled into one piece, which separates when receiving a rotary force, allowing improved attachment and removal from the developer container, enhancing the operability of the cap on the powder container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cap is used to seal the discharge port, then the container body can be securely sealed during storage and transport, but the cap becomes difficult to remove and reattach during assembly and disassembly operations
Solution Approach 1:
The cap is divided into a body portion and a separate attaching member that can be detached. The attaching member includes a gripping portion for user interaction and an engaging portion that connects to the container body. This segmentation allows the cap to maintain secure sealing during storage while enabling easy removal and reattachment during assembly operations by simply detaching the engaging portion.
2Ease of manufacture
If the cap is designed with a simple sealing structure, then manufacturing is easier and cost is reduced, but the cap cannot provide reliable sealing during both storage and assembly operations
Solution Approach 1:
The cap is divided into a body portion and a separate attaching member. The body portion provides the simple sealing structure that is easy to manufacture, while the attaching member adds the functional capability for reliable attachment and detachment. This segmentation allows each component to be optimized independently for its specific function.
Solution Approach 2:
The attaching member acts as an intermediary between the user and the cap body. It provides a gripping portion for user interaction and an engaging portion that connects to the container body, enabling reliable attachment and detachment operations without complicating the basic sealing structure of the cap body.
3Device complexity
If the cap uses a single integrated attaching structure, then the design is simpler, but the cap cannot be easily detached and reattached during assembly and disassembly
Solution Approach 1:
The attaching structure is segmented into a body portion and a separate attaching member. The attaching member includes a gripping portion for user interaction and an engaging portion that connects to the container body. This segmentation enables easy detachment and reattachment operations by simply detaching the engaging portion, while keeping the overall design relatively simple.

AI summary
A cap is configured to be attached to a developer container that discharges developer contained in the container body out of the container body through a discharge port defined in a portion of the container body. The cap includes a first attaching member and a second attaching member that are detachably assembled into one piece. When the first attaching member or the second attaching member receives a rotary force, the first attaching member and the second attaching member are separated from each other, and only the first attaching member is released from the container body.
