Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bookbinding apparatuses require large spaces and complex structures due to the need for conveying sheet bundles in various directions, leading to increased manufacturing costs and issues with adhesive application, dripping, and equipment contamination.
Innovation Solution
A bookbinding apparatus that conveys sheet bundles vertically throughout the process, simplifying the transport paths and structure, allowing for uniform adhesive application and minimizing adhesive-related issues by applying adhesive to the end face in a vertical direction and storing bundles with the adhesive side down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sheet bundles are conveyed in various directions (vertical, horizontal, oblique) to achieve adhesive application, cutting and storage, then the bookbinding apparatus can perform all necessary operations, but the apparatus size increases and manufacturing cost increases
Solution Approach 1:
The patent changes the transport path from two-dimensional (horizontal/oblique) to three-dimensional by introducing a vertical transport path. The sheet bundle is conveyed vertically from the adhesive applying portion through the cutting portion to the storage portion, eliminating the need for horizontal and oblique transport paths. This dimensional change reduces the apparatus footprint while maintaining all necessary bookbinding operations.
2Ease of manufacture
If adhesive is applied from the side to the end face of the sheet bundle lying horizontally, then adhesive application is possible, but the adhesive container requires complex sealing structures to prevent leakage due to gravity
Solution Approach 1:
Instead of applying adhesive from the side to a horizontal sheet bundle (conventional approach), the patent inverts the approach by applying adhesive from above to a vertically positioned sheet bundle. The adhesive applying portion is positioned above the sheet bundle in the vertical direction, allowing adhesive to be applied downward. This eliminates the need for complex sealing structures to prevent gravity-induced leakage, as the adhesive naturally flows in the direction of application.
3Ease of manufacture
If sheet bundle is conveyed while lying horizontally with adhesive applied, then adhesive application is possible, but the end face may contact transport path members and adhesive is removed
Solution Approach 1:
The patent changes the orientation of the sheet bundle from horizontal to vertical during transport. By conveying the sheet bundle vertically with the adhesive-coated end face facing downward, the adhesive is protected from contact with transport path members. The vertical orientation ensures that gravity keeps the adhesive in place and prevents it from being removed by friction or contact with the transport path.
4Ease of manufacture
If adhesive is applied to the end face and sheet bundle is cut while lying horizontally, then cutting is possible, but spilled adhesive adheres to the cutting blade and degrades cutting function
Solution Approach 1:
The patent inverts the conventional horizontal cutting arrangement by positioning the sheet bundle vertically during cutting. The cutting portion is positioned such that it cuts the vertically oriented sheet bundle from above. This vertical cutting orientation prevents spilled adhesive from adhering to the cutting blade, as gravity causes the adhesive to flow downward away from the blade's path, thereby maintaining cutting blade performance.
5Ease of manufacture
If bound sheet bundles are stored while lying horizontally, then storage is possible, but dripped adhesive bonds sheet bundles together
Solution Approach 1:
The patent changes the storage orientation from horizontal to vertical. The storage portion is designed to hold sheet bundles in a vertical position with the adhesive-coated end face facing downward. This vertical storage orientation prevents dripped adhesive from bonding sheet bundles together, as gravity causes the adhesive to flow downward along the end face rather than spreading horizontally to bond adjacent bundles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the size and manufacturing cost of the apparatus, prevents adhesive removal and contamination, and ensures reliable bonding without degrading the cutting function, while simplifying the adhesive application and storage processes.
Implementation Method 1
in order to prevent the adhesive to apply from leaking from the container due to the effect of gravity
Implementation Method 2
transport means for conveying the sheet bundle while letting the sheet bundle stand in the substantially vertical direction from the adhesive applying portion to the storage portion along a substantially vertical transport path
Implementation Method 3
since the direction (vertical direction) in which the adhesive spills and drips from the front cover due to gravity agrees with the direction in which a cutting blade moves, the spilled adhesive is apt to adhere to the cutting blade

AI summary
In a bookbinding apparatus, an adhesive applying portion applies an adhesive to an end face of a sheet bundle allowed to stand in the substantially vertical direction, a storage portion that gathers and stores the sheet bundle which is applied with the adhesive and bound in the adhesive applying portion while letting the sheet bundle stand in the substantially vertical direction, transport means for conveying the sheet bundle while letting the sheet bundle stand in the substantially vertical direction from the adhesive applying portion to the storage portion along a substantially vertical transport path, and a cutting portion which is provided on the transport path between the adhesive applying portion and the storage portion, and which cuts an end face of the sheet bundle while letting the sheet bundle stand in the substantially vertical direction.
