Solution Overview

Problem

Existing toner supply systems face challenges in securely mounting and dismounting toner containers, leading to potential toner leakage and inefficient toner supply due to the lack of a reliable mechanism for aligning and locking the toner discharge port with the supply port.

Innovation Solution

A developer supplier system that includes a toner container with a container shutter and a main unit shutter, where the toner container is mounted in a specific orientation and rotated to align the toner discharge port with the supply port, using elastic seals and guide mechanisms to prevent leakage and ensure secure communication between the ports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional toner supply system without a reliable alignment mechanism is used, then the structure is simple, but toner leakage occurs and toner supply reliability is poor

Engineering Contradiction:
Improvetoner supply reliabilityVSAvoidmounting mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The container shutter is designed to automatically align with the supply port through its own weight and gravitational force when the container is mounted, eliminating the need for complex external alignment mechanisms. The shutter body includes a guide portion that self-aligns with the guide groove in the supply housing, achieving reliable toner supply through self-service alignment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting structure is designed so that the container body and supply housing are positioned at the same gravitational potential level, allowing the container shutter to naturally settle into the correct position aligned with the supply port. This equipotential design enables automatic alignment without requiring additional actuators or complex positioning mechanisms.

Inventive Principle:
Principle #12Equipotentiality

2Reliability

If the container shutter is securely fastened to prevent leakage, then toner leakage is prevented, but the ease of mounting and dismounting is reduced

Engineering Contradiction:
Improveleakage preventionVSAvoidmounting and dismounting ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The container shutter is divided into separate functional segments: a shutter body for blocking the discharge port, a sheet member for sealing, and a guide portion for alignment. This segmentation allows each component to perform its specific function independently, ensuring reliable leakage prevention while maintaining ease of operation through modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container shutter acts as an intermediary element between the container body and the supply housing. It provides both the sealing function (preventing leakage) and the alignment function (through its guide portion fitting into the guide groove). This intermediary design consolidates multiple functions into a single component that does not compromise ease of mounting and dismounting.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the toner discharge port is always exposed for supply, then toner supply efficiency is high, but toner leakage occurs during mounting and dismounting

Engineering Contradiction:
Improvetoner supply efficiencyVSAvoidtoner leakage
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The container shutter is designed as a dynamic component that can move between a closed position (blocking the discharge port during mounting and dismounting) and an open position (allowing toner supply). This dynamic design enables the system to adapt its state based on operational requirements, preventing leakage during critical operations while maintaining high supply efficiency during normal operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The container shutter is positioned to close the discharge port before the actual toner supply operation begins (during mounting), and remains closed during mounting and dismounting operations. This preliminary closing action prevents toner leakage in advance, and the shutter is subsequently opened to enable efficient toner supply when needed.

Inventive Principle:
Principle #10Preliminary action

AI summary

A developer supplier includes a developer container and a main unit. The developer container includes a container body, a container seal, a developer discharge port and a container shutter. The container shutter covers or exposes the developer discharge port. The container shutter includes a container shutter body and a container sheet member. The main unit includes a housing and a main unit seal. The housing has a developer supply port. The developer container is mounted into a mounting section in a first orientation, and subsequently the container body is rotated in a first rotational direction so that the developer container changes to a second orientation and the developer discharge port communicates with the developer supply port. The container sheet member has a downstream end and configured to come into contact with the main unit seal when the developer container is mounted into the mounting section in the first orientation.
