Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-processing devices for image forming apparatuses suffer from uneven accumulation of cut edges in the collection box, leading to inconsistent distribution of waste edges.
Innovation Solution
Incorporation of a blower that blows gas into the collection container to disrupt the accumulation of cut edges, using a controller to periodically adjust the wind pressure and direction of the gas flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cut edges are collected in a collection box without intervention, then the collection process is simple, but the edges accumulate unevenly inside the collection box
Solution Approach 1:
The patent applies pneumatic principles by using a blower to generate gas flow that blows cut edges inside the collection box. This pneumatic action redistributes the edges uniformly without requiring complex mechanical mechanisms, maintaining operational simplicity while achieving even distribution.
Solution Approach 2:
The patent changes the physical state and movement parameters of the cut edges by introducing gas flow. The blower modifies the velocity and direction parameters of gas to actively transport and redistribute edges, transforming the static accumulation process into a dynamic control process that achieves uniform distribution.
2Stability of the object's composition
If a blower is added to distribute edges uniformly, then the edge distribution becomes even, but the device complexity increases
Solution Approach 1:
The patent uses pneumatic flow from a blower as a simple yet effective mechanism to achieve uniform edge distribution. This approach avoids complex mechanical systems such as conveyors or robotic manipulators, adding minimal complexity while solving the distribution problem efficiently.
Solution Approach 2:
The patent introduces gas as an intermediary medium to transfer and distribute cut edges within the collection box. The gas flow acts as a mediator that carries edges to their target positions without requiring direct mechanical contact or complex positioning mechanisms, thereby simplifying the overall system.
3Device complexity
If edges are allowed to accumulate naturally, then no additional components are needed, but the operational efficiency decreases due to uneven stacking
Solution Approach 1:
The patent employs pneumatic flow to actively manage edge accumulation, ensuring uniform stacking that maximizes collection box capacity utilization. This prevents premature saturation of the collection box, allowing continuous operation for longer periods and improving overall productivity without requiring frequent emptying.
Solution Approach 2:
The patent performs preliminary distribution of edges using gas flow as they are being collected, rather than addressing uneven accumulation after the fact. This proactive approach ensures uniform distribution throughout the collection process, maintaining optimal operational efficiency and preventing bottlenecks.

AI summary
A post-processing apparatus includes a cutter that cuts an edge of a transported recording medium, a collection container that is disposed below the cutter and that collects the edge when the edge cut by the cutter falls downward, and a blower that blows gas into the collection container.
