Off-line Response Card Registration via Virtual User ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for registering off-line response cards are time-consuming and require user identity information, limiting the ability to perform continuous systematic evaluation and statistics across multiple cards.
Innovation Solution
The solution involves assigning a unique card ID to each off-line response card, generating a virtual user ID if necessary, and associating subsequent cards with the same virtual user ID, allowing for easy and fast registration without requiring user identity input, using a database to store and retrieve virtual user IDs and card information via a short-range communication link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user identity information is collected and processed, then statistics and systematic evaluation can be performed, but the registration process becomes time-consuming and complex
Solution Approach 1:
The patent introduces a virtual user ID as an intermediary that links multiple response cards to a user without requiring direct collection of personal identity information. This mediator enables systematic evaluation and statistics while keeping the registration process simple and fast, as the system only needs to read card IDs and match them with virtual user IDs in the database.
Solution Approach 2:
The patent creates a virtual representation (virtual user ID) that copies the essential linking function of personal identity without requiring the actual personal data. This allows the system to perform statistics and evaluation based on the virtual copies, maintaining reliability while reducing registration complexity and time.
2Loss of information
If personal identity information is required for registration, then accurate statistics can be gathered, but user anonymity is compromised and registration becomes more difficult
Solution Approach 1:
The virtual user ID serves as an intermediary that preserves user anonymity while enabling accurate statistics. The system can track and evaluate user responses through the virtual ID without ever needing to collect or store sensitive personal identity information, thus maintaining both statistics accuracy and registration ease.
Solution Approach 2:
The patent extracts only the essential linking function from personal identity information, creating a minimal virtual user ID that contains no personal data but is sufficient for statistical purposes. This extraction allows the system to gather accurate statistics while removing the burden of personal information collection from the registration process.
3Measurement precision
If multiple response cards are processed individually, then each card can be evaluated, but continuous systematic evaluation across plurality of cards is not achieved
Solution Approach 1:
The patent merges multiple response cards with the same virtual user ID into a unified evaluation system. By reading card IDs and matching them with virtual user IDs in the database, the system automatically groups multiple cards and performs continuous systematic evaluation across all of them, achieving both precise individual card evaluation and efficient aggregate analysis.
Solution Approach 2:
The system implements feedback by continuously reading card IDs, checking the database for virtual user ID associations, and automatically updating the systematic evaluation. This feedback loop enables continuous processing of multiple cards without manual intervention, improving productivity while maintaining measurement precision through consistent database lookups and associations.

AI summary
Every off-line response card to be registered comprises a card ID identifying the off-line card uniquely. In the registering process the card ID of a first off-line response card is read and a virtual user ID associated with the card ID of the first off-line response card is obtained. Afterwards, the obtained virtual user ID, for example, can be associated with card IDs of any subsequent off-line response card.
