Solution Overview

Problem

Conventional paper-based voting systems face inefficiencies in processing provisional ballots, particularly in maintaining voter anonymity and requiring manual handling of multiple envelopes, which complicates the inclusion or exclusion of ballots in election results.

Innovation Solution

A voting system that includes a ballot tabulation device linked with an election management system, where provisional ballots are assigned a unique identification code, allowing for the creation of a cast vote record (CVR) and a link between the CVR and the voter code, enabling the system to update election results based on eligibility determinations without compromising voter anonymity, and optionally supports risk-limiting audits by using unique ballot codes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling of multiple envelopes is used to process provisional ballots, then voter anonymity is maintained, but processing efficiency decreases and complexity increases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidenvelope handling complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical process of handling multiple envelopes with an automated electronic system. The ballot scanner automatically reads barcodes on ballots, the computer system processes eligibility determinations electronically, and results are updated automatically without manual envelope manipulation. This substitution of mechanical handling with electronic processing directly resolves the contradiction by improving efficiency while reducing operational complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates electronic copies and representations of ballot information through barcode scanning and digital record-keeping. Instead of physically manipulating original ballots through multiple envelopes, the system uses digital copies and data representations to track and process provisional ballots, eliminating the need for complex physical envelope handling while maintaining security and anonymity protocols.

Inventive Principle:
Principle #26Copying

2Productivity

If all provisional ballots are included in initial election results, then processing speed is improved, but accuracy decreases due to potential ineligible votes

Engineering Contradiction:
Improveelection result processing speedVSAvoidelection result accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs preliminary eligibility screening and provisional ballot identification before final result certification. The system flags provisional ballots in advance, allows for eligibility verification before inclusion in final results, and provides mechanisms for post-election adjudication. This preliminary action ensures that while processing can begin quickly, accuracy is maintained through pre-processing validation steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where election officials can review and adjudicate provisional ballot eligibility after initial counting. The system allows for post-election verification and correction of provisional ballot inclusions, providing a feedback loop that ensures accuracy while maintaining initial processing speed. Eligibility determinations can be made and applied after the fact without requiring slow pre-verification of all provisional ballots.

Inventive Principle:
Principle #23Feedback

AI summary

A voting system comprises a ballot tabulation device that tabulates each of a plurality of paper ballots by determining one or more contest selections marked on the paper ballot and storing the contest selections within a cast vote record (CVR) for the paper ballot. One or more of the paper ballots comprises a provisional ballot on which is printed an identification code that represents or is associated with a voter code assigned to a voter who cast the provisional ballot. During the tabulation process, a direct or indirect link is provided between the CVR and the voter code for the provisional ballot. The voting system also comprises an election management system that identifies the CVR associated with each of one or more inputted voter codes, i.e., the voter codes assigned to voters who have had a change in eligibility status, and updates the total vote count to include or exclude the contest selections stored within that CVR as applicable. Preferably, the election management system is configured to prevent a user from accessing the contest selections stored in the CVR for the provisional ballot based on the voter code. For audit purposes, a ballot code may also be printed on each paper ballot, wherein the ballot code may optionally serve as the identification code for a provisional ballot.
