Direct Mail Passphrase Generation for Unique, Easy Code Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing direct mail engagement methods using long, random numeric or alphanumeric codes are inconvenient for recipients, leading to low engagement rates due to difficulty in relaying or inputting codes, and managing unique codes for large recipient bases is challenging, with existing systems failing to balance ease of use and uniqueness.
Innovation Solution
A software-based process generates recipient-friendly, word-based passphrases, which are assigned to direct mail recipients, enhancing engagement by making the process more intuitive and efficient, with systems like passphrase generation, mapping, and offer processing subsystems managing and tracking passphrase status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If long, random numeric or alphanumeric codes are used for direct mail engagement, then uniqueness for large recipient bases is achieved, but ease of operation deteriorates due to difficulty in relaying or inputting codes
Solution Approach 1:
The patent changes the parameter of the engagement code from long numeric/alphanumeric sequences to short word-based passphrases. This parameter change maintains uniqueness through systematic generation while dramatically improving ease of operation, as recipients can easily speak, read, and input word-based passphrases compared to lengthy code sequences.
Solution Approach 2:
The patent applies local quality by making different parts of the code system have different characteristics. The passphrases use common, easy-to-process words for recipient interaction, while the underlying system maintains uniqueness through sophisticated generation and tracking mechanisms. Each passphrase is locally optimized for human interaction while the global system ensures uniqueness.
2Ease of operation
If word-based passphrases are used instead of long codes, then ease of operation improves for recipients, but ensuring uniqueness for large recipient bases becomes challenging
Solution Approach 1:
The patent segments the passphrase generation process into multiple independent components: a first set of words selected from a large vocabulary, a second set of words selected from another large vocabulary, and combination logic that merges these sets. This segmentation allows the system to generate unique passphrases from manageable word sets, ensuring uniqueness even with limited vocabulary sizes.
Solution Approach 2:
The patent implements a nested structure where passphrases are composed of nested word sets. The first set of words is nested within the passphrase structure, and the second set of words is nested within the same passphrase. This nested arrangement allows systematic generation of unique combinations while maintaining simplicity in the final passphrase form.
3Reliability
If sophisticated code management systems are implemented to track unique codes, then reliability of code uniqueness is improved, but device complexity increases
Solution Approach 1:
The patent uses copying by generating passphrases from template structures rather than creating entirely unique complex codes. The system copies from predefined word sets and combines them according to established rules, which simplifies the management infrastructure compared to generating and tracking completely arbitrary unique codes for each recipient.

AI summary
A computing platform is configured to: (i) obtain a pool of available words for use in generating four-word passphrases, (ii) generate a candidate batch of four-word passphrases using the pool of available words, (iii) identify one or more duplicate four-word passphrases in the candidate batch and then filter the identified one or more duplicate four-word passphrases out of the candidate set; (iv) based on the filtered candidate batch of four-word passphrases, generate a new batch of four-word passphrases for use on direct mail; and (v) release the new batch of four-word passphrases for use on direct mail.
