Solution Overview

Problem

Existing systems lack a standardized method for collecting and securely storing evidence of property condition before and after rentals, leading to disputes over security deposits due to insufficient documentation by renters, often resulting in partial or full deposit loss.

Innovation Solution

A system utilizing image and document capture devices, connected to a server with database and internet access, to compare pre- and post-rental conditions, flag differences, and calculate deposit refunds based on item-specific damage assessments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If renters manually document property conditions using lists, diagrams, notes, or pictures, then evidence collection becomes possible, but the process is inconsistent, incomplete, and lacks standardization

Engineering Contradiction:
Improveevidence collection reliabilityVSAvoiddocumentation process complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system segments the property inspection into multiple standardized categories (walls, floors, ceilings, windows, doors, fixtures, appliances) with specific inspection criteria for each. This segmentation ensures comprehensive and consistent evidence collection across different properties and inspectors, resolving the inconsistency problem while maintaining ease of use through automated guidance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transforms subjective manual documentation into objective standardized parameters through automated image analysis and structured data collection. By converting visual inspections into standardized digital records with consistent formatting and classification, the system achieves both reliability through standardization and ease of operation through automation.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If renters fail to collect adequate evidence at appropriate times, then disputes over property condition arise, but the renter loses part or all of the security deposit

Engineering Contradiction:
Improvedeposit refund reliabilityVSAvoidproperty condition documentation
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary documentation of property conditions at the start of the rental period, creating baseline records before any potential damage occurs. This preliminary action ensures that all property conditions are captured and compared against at the time of move-out, eliminating the risk of losing deposit refunds due to insufficient evidence collection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides continuous feedback to renters about property condition status throughout the rental period, reminding them to document any changes or damages. This feedback mechanism ensures renters maintain adequate evidence without needing to remember all documentation requirements, thereby protecting their deposit refund reliability.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the system compares pre-rental and post-rental images to determine property condition changes, then accurate damage assessment becomes possible, but the system complexity increases

Engineering Contradiction:
Improveproperty condition comparison precisionVSAvoidimage processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system creates digital copies of property conditions through standardized photography and documentation protocols. These copies are stored and compared algorithmically to detect changes, achieving precise measurement through digital replication rather than complex physical measurement systems, thus maintaining ease of operation while improving precision.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system replaces manual visual comparison and subjective assessment with automated image processing algorithms. By substituting mechanical/visual inspection with computational analysis, the system achieves high measurement precision for property condition comparison while reducing the complexity of manual operation and expertise requirements.

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

4Ease of operation

If the system automatically calculates deposit refunds based on damage assessment, then fair and transparent refund determination is achieved, but the automation extent increases system complexity

Engineering Contradiction:
Improverefund calculation transparencyVSAvoidautomated processing system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs self-service automation by automatically comparing pre and post-rental documentation, assessing damages, and calculating refund amounts without requiring manual intervention. This self-service approach provides transparent and fair refund determination while the automation is built into the system architecture rather than adding external complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A system and method for acquiring, collecting, comparing and evaluating the condition of rental property at several time periods during a lease or rental agreement. A first image is compared to a second image, a deposit amount remaining is calculated based on the image comparison. The remaining deposit amount is paid using an electronic format.
