Developer Supply Container Seal Tape Adhesion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional developer supply containers face issues with seal tape adhering to the seal piece during assembly, leading to damage and leakage, resulting in a low manufacturing yield rate and inadequate sealing due to insufficient seal piece width and improper sealing mechanisms.
Innovation Solution
A developer supply container design featuring a cover plate with a gap and through hole, allowing the seal tape to be mounted separately from the seal piece, with a pad to prevent accidental adhesion and a door member for controlled sealing, enhancing the anti-leak effect and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seal tape is applied to cover the seal piece on the container body, then the developer supply port can be sealed, but the seal tape may adherively bond to the seal piece causing damage and deterioration of sealing effect
Solution Approach 1:
The invention divides the sealing system into separate functional components: the seal piece remains mounted on the container body while the seal tape is applied to the cover plate. This segmentation prevents the seal tape from contacting and bonding to the seal piece, eliminating the risk of seal piece damage during assembly and removal processes.
Solution Approach 2:
The cover plate acts as an intermediary element between the seal piece and the seal tape. The seal tape is applied to the outer surface of the cover plate rather than directly to the seal piece, serving as a mediator that provides sealing functionality without causing harmful adhesion to the seal piece.
2Area of stationary object
If seal tape is arranged outside the seal piece with wider width, then sealing coverage is improved, but the seal tape may damage or escape due to pull when door member is assembled
Solution Approach 1:
The invention merges the sealing functions of the seal piece and seal tape by positioning both to overlap and work together. The seal piece on the container body and the seal tape on the cover plate create a combined sealing system that provides both wide coverage and enhanced stability, preventing the seal tape from damaging or escaping during assembly.
3Area of stationary object
If seal tape width is limited by container body width, then mounting space is constrained, but the anti-leak effect may be insufficient due to limited seal piece width
Solution Approach 1:
The invention extends the sealing system into a new dimension by applying the seal tape to the cover plate rather than solely on the container body. This dimensional extension allows the seal tape to achieve greater effective width and coverage area without being constrained by the limited width of the container body, thereby enhancing the anti-leak effect.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents seal tape and seal piece damage during assembly, maintains effective sealing, and increases manufacturing yield by allowing wider seal piece widths and controlled seal tape application, ensuring reliable developer containment and reduced waste.
Implementation Method 1
a seal tape having a width wider than that of the seal piece is used and adhered by heat pressing on a portion of a container body
Implementation Method 2
a seal piece of foam material is provided... the seal piece will seal the surrounding of the developer supply port

AI summary
A developer supply container includes a cover plate mounted on an outer surface of a container body and provided with an opening corresponding to a developer supply port of the container body, which is sealed by a seal tape. The seal tape has a folded section extending through a gap between the container body and the cover plate and a through hole of the cover plate such that an end portion of the seal tape is exposed. A seal piece is mounted on an outer surface of the cover plate. On the outer surface of the container body a door member is slidably mounted. The developer supply container can prevent developer from leak out and has a good manufacturing yield rate.
