Self-Use Forensic Sample Kit with Blockchain Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current personal use sample collection kits lack the security and legal forensic standards necessary for collecting evidence in criminal and tort cases, particularly in situations where in-person assistance is not feasible, such as sexual assault cases, leading to potential tampering and inaccurate evidence presentation.
Innovation Solution
A self-use sample collection kit with tamper-evident and tamper-resistant features, combined with an integrated application for electronic monitoring and blockchain-based data storage, allowing for secure, self-directed evidence collection and tracking that meets forensic and evidentiary standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hospital sexual assault examination kits are used, then evidence can be collected by trained professionals, but the process requires in-person hospital visits which traumatized victims may be unwilling or unable to undergo
Solution Approach 1:
The patent enables self-service by providing a complete sexual assault examination kit that victims can use independently at home. The kit includes all necessary collection tools, tamper-evident packaging, and instructions, allowing the victim to collect evidence without requiring in-person hospital visits or trained examiners present during collection.
Solution Approach 2:
The examination process is segmented into discrete, manageable steps that the victim can perform independently. The kit is divided into multiple components (collection swabs, containers, tamper-evident seals, packaging) that correspond to different collection tasks, making the complex procedure accessible and manageable for self-collection.
2Ease of operation
If self-use sample collection kits are used, then victims can collect evidence privately without in-person assistance, but the kits lack the security and legal forensic standards necessary to prevent tampering
Solution Approach 1:
The patent applies preliminary anti-action by incorporating tamper-evident features into the collection system before use. These features include tamper-evident seals on containers, sealed packaging with destruction mechanisms, and chain-of-custody tracking systems that automatically detect and alert if tampering occurs, preventing fraudulent evidence presentation before it can affect legal proceedings.
Solution Approach 2:
The system incorporates feedback mechanisms through tamper-evident seals that change state when opened, electronic tracking systems that monitor package integrity, and chain-of-custody documentation that records every handling event. This feedback allows the system to detect tampering attempts and provide alerts to appropriate authorities.
3Reliability
If victims are required to present at hospitals for forensic exams, then professional collection can be ensured, but the requirement precludes many traumatized victims from coming forward
Solution Approach 1:
By enabling self-service collection at home, the patent removes the barrier of requiring victims to travel to and undergo formal hospital examinations. Victims can privately collect evidence in their own safe environment, eliminating the trauma and shame associated with hospital visits while maintaining collection reliability through standardized protocols and tamper-evident features.
Solution Approach 2:
The kit enables preliminary action by allowing victims to collect and secure evidence immediately after the assault occurs, before any pressure to report or travel to hospitals arises. The self-collection capability is activated at the moment the victim is most vulnerable, preserving evidence before subsequent hospital visits or legal pressures might interfere.
4Ease of manufacture
If traditional collection kits are used, then basic sample collection is possible, but the kits do not provide security necessary where the possibility of tampering is a legal issue
Solution Approach 1:
The patent incorporates preliminary anti-action measures including tamper-evident seals that change appearance when opened, sealed containers with destruction mechanisms that prevent reuse, and chain-of-custody tracking systems that automatically detect unauthorized handling. These features address tampering risks before they can compromise evidence integrity.
Solution Approach 2:
The system introduces intermediary elements between the collection point and the courtroom, including tamper-evident packaging, sealed containers with unique identifiers, and electronic tracking systems. These intermediaries act as protective barriers that detect and prevent tampering while maintaining the integrity of the evidence chain.
