Document Rack with Integrated Pocket for Validator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill handling machines lack a mechanism to collectively retain and prevent the scatter of documents discharged from validators, leading to potential contamination.
Innovation Solution
A document rack with a housing structure featuring a front wall, back wall with a notch, and bottom wall, which includes an inner chamber for the validator and a pocket to receive and retain documents, preventing scatter and contamination, and allowing easy retrieval for reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If documents are discharged from the validator onto a tray, then documents can be returned to the inlet, but documents scatter and become contaminated
Solution Approach 1:
The rack is nested within the validator housing structure, with the pocket integrated into the lower portion of the rack housing. This nesting arrangement allows the rack to occupy space within the existing validator assembly without requiring external mounting, thereby containing documents within a protected internal structure rather than exposing them on an external tray.
Solution Approach 2:
The rack acts as an intermediary structure between the validator outlet and the inlet. Documents are discharged into the rack's pocket rather than directly onto a tray, and from there can be returned to the inlet. This intermediate containment structure prevents direct exposure to contamination while maintaining the return function.
2Ease of operation
If documents are kept at the inlet with leading edge projecting outward, then users can draw documents out, but documents are not collectively retained and may scatter
Solution Approach 1:
Instead of keeping documents in a horizontal arrangement at the inlet level, the rack utilizes the vertical dimension by positioning the pocket in the lower portion of the housing. Documents are discharged downward into the pocket and can be retrieved from below, changing the retrieval dimension from horizontal to vertical while maintaining ease of access.
Solution Approach 2:
The rack's pocket structure is预先 designed to receive and hold documents in a contained manner before retrieval. Documents are deposited into the pocket in an organized fashion rather than being scattered on a tray, preparing them for orderly retrieval while preventing scatter during the transition from validator to storage.
3Object-affected harmful factors
If a rack structure is added to contain documents, then scatter and contamination are prevented, but device complexity increases
Solution Approach 1:
The rack housing is segmented into functional portions: an upper inner chamber for the validator and a lower pocket for document storage. This segmentation allows each portion to be optimized for its specific function while maintaining a relatively simple overall structure that can be integrated into the validator assembly.
Solution Approach 2:
The rack structure serves multiple functions: it provides a containment housing for the validator, creates a protected pocket for document storage, and facilitates document retrieval. By combining these functions into a single integrated structure rather than separate components, the design achieves document protection without proportionally increasing complexity.

AI summary
A document rack is provided to comprises a front wall 4 formed with at least one opening 7, a back wall 5 formed with at least one notch 5a, and a bottom wall 6 for connecting lower ends of front and back walls 4, 5 to structurally constitute a housing 3. A front portion 2 of a document validator 1 may be arranged in inner chamber 10 through notch 5a of back wall 5 so that users can easily take out documents in a lump from a pocket 13 of the document rack for reuse of documents because pocket 13 may receive and retain documents dispensed from document validator 1 to prevent scatter and contamination of the discharged documents.
