Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Booklet making apparatuses using metal staples hinder recycling, and integrating post-processing units for adhesive toner bonding increases the size of the apparatus.
Innovation Solution
A booklet making apparatus with a receiving unit, heating unit, and pressing unit that uses adhesive toner to bond sheets through heat and pressure, eliminating the need for staples and reducing the apparatus size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal staples are used to bind sheets, then the booklet binding strength is improved, but the recyclability of the booklet deteriorates
Solution Approach 1:
The patent replaces the mechanical stapling system with a thermal bonding system. The image forming apparatus forms adhesive toner images on sheets, and the post-processing apparatus heats and presses these adhesive layers to bond sheets together, eliminating metal staples and enabling recycling.
Solution Approach 2:
The patent changes the bonding mechanism from mechanical (staples) to thermal (heated adhesive toner). The post-processing apparatus applies controlled heat and pressure to activate the adhesive properties of the toner layer, creating a strong bond without metal fasteners.
2Reliability
If a post-processing apparatus with alignment unit and thermocompression bonding unit is connected to image forming apparatus, then the adhesive bonding function is improved, but the apparatus size increases
Solution Approach 1:
The patent combines the image forming apparatus and post-processing apparatus into an integrated system. The image forming apparatus forms images and adhesive toner layers, while the post-processing apparatus provides heating and pressing functions, creating a unified booklet making apparatus that maintains reliability while optimizing space.
Solution Approach 2:
The post-processing apparatus serves multiple functions: it heats the adhesive toner layers, presses the sheets for bonding, and can be integrated with the image forming apparatus. This multi-functionality reduces the need for separate dedicated devices, thereby controlling overall apparatus size.
