Document Stacker With Inward Projected Surfaces for Deviated Sheet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill stackers face challenges in storing decentered documents without a centering device, leading to increased manufacturing costs and compatibility issues with limited outer configurations.
Innovation Solution
A stacker design featuring a pusher mechanism and backup plate system that adjusts to accommodate documents with tolerable deviations, using a pair of inward projected surfaces and a spring-actuated backup plate to align and store decentered documents within a vault.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a centering device is added to align decentered documents, then document alignment is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The stacker uses its own pusher mechanism and backup plate to perform the centering function that would otherwise require a separate centering device. The pusher pushes documents against the backup plate, allowing the stacker's existing components to self-correct decentered documents without external assistance
Solution Approach 2:
The backup plate serves dual functions: it acts as a support surface for documents during stacking and simultaneously functions as a centering element. By positioning the backup plate at specific locations within the stacking chamber, it provides both structural support and alignment correction in a single component

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient storage of documents with tolerable deviations, allowing for easy retrieval without the need for a centering device, reducing manufacturing costs and enhancing compatibility with compact configurations.
Implementation Method 1
a backup plate (9) disposed within vault (30) for parallel movement of backup plate (9) to the moved direction of pusher (11), and a spring (10) disposed in vault (30) for resiliently urging backup plate (9) toward protrusions (6)

AI summary
The stacker comprises a pair of protrusions 6 prominent from side walls 5 in a spaced relation to each other to form a second opening 7 between protrusions 6, an interim chamber 13 defined by partitions 3 and protrusions 6, and a pair of inner surfaces 8 formed on protrusions 6 prominent into interim chamber 13 from side walls 5 more inward than side surfaces of a holding chamber 12. Largely deviated one of side edges of document D comes into contact to inner surface 8 in interim chamber 13 to push document D inward by projection of inner surface 8 to store document D in a vault 30 with the tolerable deviation upon stowage of a subsequent document D.
