Postprocessing Apparatus Common Moving Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing postprocessing apparatuses require separate driving systems and control systems for each postprocessing member, and a guide member with a branch path to retract the non-used member, which complicates the design and increases complexity.
Innovation Solution
A postprocessing apparatus with a common moving mechanism for two postprocessing members, where a mounting base with a guide member allows both members to be moved along a single path, eliminating the need for a retracting path and simplifying the guide member design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two postprocessing members are provided independently with separate driving systems and control systems, then each member can perform its function reliably, but the device complexity increases
Solution Approach 1:
The patent merges two separate postprocessing members (staple binding member and stapleless binding member) onto a single mounting base, allowing them to be moved together by a common moving mechanism along a shared guide rail. This consolidation eliminates the need for separate driving systems and control systems for each member, directly reducing device complexity while maintaining the functional reliability of both binding operations
Solution Approach 2:
The mounting base serves as a universal platform that can accommodate and transport multiple different postprocessing members (both staple and stapleless binding members) using the same moving mechanism. This multi-functional design allows a single driving system and control system to manage multiple postprocessing operations, resolving the contradiction between reliability and complexity
2Adaptability or versatility
If a guide member with a branch path is used to retract the non-used postprocessing member, then the members can be independently positioned, but the guide member design becomes more complex
Solution Approach 1:
The patent extracts and eliminates the unnecessary branch path structure from the guide member. Instead of having complex branching paths for retracting non-used members, the invention uses a single linear guide rail where both postprocessing members are moved along the same path. The mounting base enables independent positioning of members without requiring the guide member itself to have complex retracting paths, thus simplifying the guide member design while maintaining positioning flexibility
Solution Approach 2:
Rather than making the guide member complex with branch paths to achieve member retraction, the invention inverts the approach by making the mounting base movable. This allows the postprocessing members to be independently positioned and retracted through the movement of their shared mounting base, eliminating the need for complex guide member structures and achieving the same adaptability with simpler guide rail design

AI summary
A postprocessing apparatus includes: a first postprocessing member that performs postprocessing on a recording medium; a second postprocessing member that differs from the first postprocessing member and performs postprocessing on the recording medium; a mounting base to which the first and second postprocessing members are mounted; a support plate having a guide member that guides movement of the mounting base; and a moving mechanism that moves the mounting base along the guide member.
