Developer Container Support Structure for Discharge Port Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing developer containers face challenges in maintaining the sealability of the discharge port due to potential deformation or damage of the extending portion, which is not adequately supported.
Innovation Solution
The developer container is designed with an extending portion that includes a support portion on the opposite surface to the opening and closing portion, featuring a wider flat surface to enhance sealability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flat surface portion of the attachment portion is widened to secure sealability of the discharge port, then the sealability is improved, but the extending portion becomes more prone to deformation or damage
Solution Approach 1:
The attachment portion is divided into a main body and an extending portion, with the extending portion further segmented into a flat surface portion and a support portion. This segmentation allows the flat surface to be widened for sealing while the support portion provides structural reinforcement, resolving the contradiction between sealability and deformation resistance.
Solution Approach 2:
The support portion acts as an intermediary structural element between the widened flat surface portion and the main body of the attachment portion. It mediates the mechanical stress, allowing the surface to be widened for sealing purposes while preventing deformation through the support structure.
2Reliability
If the extending portion is made wider to improve sealability, then the sealing performance is enhanced, but the complexity of the attachment portion increases
Solution Approach 1:
The support portion is merged with the main body of the attachment portion through integral formation or secure attachment, combining the sealing function of the widened flat surface with the structural function of the support in a unified component. This reduces overall complexity compared to using separate independent elements.
Solution Approach 2:
The attachment portion is designed as a multi-functional component where the main body provides structural support, the extending portion provides sealing surface, and the support portion provides reinforcement. This universal design integrates multiple functions into a single component, avoiding the complexity of multiple separate parts.

AI summary
A developer container includes: an accommodation portion that accommodates a developer; a discharge port through which the developer is discharged from an outer peripheral portion of the accommodation portion on a front end side in a mounting direction; an opening and closing portion that opens and closes the discharge port from an outside; an attachment portion that surrounds the discharge port and to which the opening and closing portion is movably attached, in which the attachment portion has an extending portion extending toward the front end side in the mounting direction, and the extending portion is provided with a support portion that supports the extending portion on a surface opposite to the opening and closing portion.
