Solution Overview

Problem

Current pain management strategies face challenges with side effects and resistance issues from traditional analgesics, and there is a need for new approaches and targets for pain therapy, particularly in treating chronic pain.

Innovation Solution

The method involves using a test system comprising Ifi205 nucleic acid or protein to identify compounds involved in pain by detecting significant effects of test compounds on the system, which can lead to the development of therapeutic agents for pain treatment, including neuropathic pain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional analgesics are used for pain treatment, then pain relief is achieved, but side effects and resistance occur

Engineering Contradiction:
Improvepain relief effectivenessVSAvoidside effects and resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the molecular target parameter from traditional analgesic targets to the Ifi205 protein target. By identifying and targeting Ifi205, which is specifically involved in neuropathic pain pathways, the invention achieves pain relief through a different molecular mechanism, thereby avoiding the side effects and resistance associated with traditional analgesics that target conventional pathways.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If new pain therapy targets are developed, then treatment effectiveness improves, but development complexity increases

Engineering Contradiction:
Improvetreatment effectivenessVSAvoiddrug development complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary identification and characterization of the Ifi205 target before drug development. By first establishing Ifi205 as a valid therapeutic target through genetic studies and functional analysis, the invention creates a solid foundation that simplifies subsequent drug discovery efforts. This preliminary validation reduces the overall development complexity compared to starting de novo target identification.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If Ifi205-based test systems are used for compound identification, then novel pain compounds are discovered, but testing complexity increases

Engineering Contradiction:
Improvecompound identification rateVSAvoidtest system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses the Ifi205 protein or its nucleic acid as an intermediary element in the test system. This intermediary serves as a specific binding target that mediates the interaction between test compounds and the pain pathway. By using this well-defined intermediary, the system achieves high specificity in compound identification while managing complexity through a focused, single-target approach rather than complex multi-parameter systems.

Inventive Principle:
Principle #24Intermediary (Mediator)
