Solution Overview
Problem
Manufacturers face difficulties in determining whether device damage is due to user negligence, making it challenging to enforce warranty conditions for complex and fragile electronics.
Innovation Solution
A system that uses machine learning and natural language processing to analyze user statements and sensor data from devices, correlating events to provide a credibility score that validates or refutes user claims about device usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manufacturers rely on user self-reporting for warranty claims, then the process is simple and quick, but the accuracy and reliability of damage cause determination deteriorates
Solution Approach 1:
The patent introduces sensor data as an intermediary element that objectively mediates between the user's claim and the manufacturer's assessment. Sensors continuously monitor device conditions (temperature, humidity, impact, usage patterns) and provide verifiable data that neither party can manipulate, thus maintaining process simplicity while dramatically improving determination accuracy.
Solution Approach 2:
The patent replaces the mechanical system of subjective human assessment (user statements and manufacturer judgment) with an automated data-driven system. Machine learning models analyze sensor data objectively, substituting human subjectivity with algorithmic precision, thereby improving measurement precision without complicating the operational workflow.
2Measurement precision
If manufacturers implement detailed inspection procedures to accurately determine damage causes, then measurement precision improves, but device complexity and inspection time increase
Solution Approach 1:
The patent implements preliminary action by having sensors continuously collect and pre-process data during normal device operation. Damage-related parameters (temperature excursions, impact events, usage patterns) are monitored and stored before any warranty claim occurs. This eliminates the need for complex post-damage inspection systems, as the data is already captured and prepared for analysis.
Solution Approach 2:
The patent creates a digital copy of the physical device's operational state through sensor data. Instead of physically inspecting the device to determine damage causes, the system analyzes a digital replica of the device's usage history and environmental conditions, significantly reducing inspection system complexity while maintaining high determination accuracy.
3Measurement precision
If manufacturers collect and analyze extensive sensor data to validate user claims, then credibility assessment accuracy improves, but data processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-processing and organizing sensor data during device operation into meaningful features and patterns. Data is aggregated, filtered, and structured in advance, so that when a warranty claim occurs, the machine learning model receives pre-prepared inputs rather than raw unprocessed data, dramatically reducing processing time while maintaining accuracy.
Solution Approach 2:
The patent implements partial action by focusing data collection and analysis only on the specific parameters relevant to the claimed damage type. Rather than analyzing all possible sensor data equally, the system selectively processes only the pertinent features needed to assess that particular claim, reducing computational overhead while preserving credibility assessment accuracy.

AI summary
In an approach for detecting customer usage of a device and validating a customer claim about the device, a processor receives a statement from a user describing usage of a device. A processor identifies correlating events of the usage of the device via applying natural language processing techniques to the statement. A processor analyzes sensor data from the device via applying a learning model, the learning model being pre-trained to associate the sensor data with physical events. A processor provides a credibility score to the statement based on the analysis of the sensor data and the correlating events exacted from the statement.
