Solution Overview
Problem
Conventional developer replenishing containers face challenges in dissolving developer aggregation due to their complex configurations and reliance on small discharge ports, which can lead to inefficient developer discharge and increased energy consumption in image forming apparatuses.
Innovation Solution
A developer replenishing container with a simple configuration featuring a conveyance part that rotates to convey developers, a displacement part that reciprocates near the discharge port, and a biasing member that expands to facilitate developer discharge, allowing for efficient developer replenishment and minimizing aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a small discharge port is used to suppress developer scattering, then developer scattering is reduced, but developer aggregation occurs at the discharge port
Solution Approach 1:
The patent introduces a vibration member that vibrates in the discharge path to prevent developer aggregation. The vibration mechanically disrupts aggregated developer particles, allowing smooth discharge through the small discharge port while preventing both scattering and aggregation issues.
Solution Approach 2:
The patent changes the physical state of the discharge path by introducing vibration. This parameter change (from static to dynamic vibration) prevents developer aggregation without requiring a larger discharge port, thus maintaining the benefit of reduced scattering.
2Object-generated harmful factors
If a reciprocating member with crank mechanism is used to prevent developer aggregation, then developer aggregation is prevented, but device complexity increases
Solution Approach 1:
The patent extracts and eliminates the complex crank mechanism from the system. Instead of using a reciprocating member driven by a crank, the invention uses a simpler vibration member that can be driven directly by a motor or other simple drive mechanism, significantly reducing device complexity while maintaining the anti-aggregation function.
Solution Approach 2:
The patent replaces the mechanical crank mechanism with a direct vibration generation system. The vibration member is driven directly by a motor or actuator without intermediate mechanical conversions, substituting a complex mechanical transmission system with a simpler direct-drive vibration system.
3Object-generated harmful factors
If a reciprocating member with crank mechanism is used to drive the reciprocating member, then developer aggregation is prevented, but energy consumption increases
Solution Approach 1:
The patent removes the energy-consuming crank mechanism from the system. The simplified vibration member requires less energy to operate compared to the complex reciprocating mechanism with crank, directly reducing energy consumption while maintaining the developer anti-aggregation function.
Solution Approach 2:
The patent substitutes the energy-intensive mechanical crank mechanism with a more energy-efficient direct vibration system. The simplified drive system reduces energy losses associated with mechanical transmission and conversion, lowering overall energy consumption.
