Solution Overview

Problem

Conventional hypochlorite solutions often leave residues on tissue surfaces after disinfection, posing local undesirable effects, especially with higher concentrations, necessitating improved antiseptic solutions that eliminate active antiseptic remnants to avoid oxidation damage.

Innovation Solution

A device and kit system that uses a solid form antiseptic active ingredient, which is dissolved in a sterile saline solution, allowing for efficient delivery and neutralization by a reduction agent, ensuring no toxic residues are left on tissue surfaces, with pH control to prevent tissue damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hypochlorite solutions are used for disinfection, then antiseptic effect is achieved, but residues remain on tissue surfaces causing local adverse effects

Engineering Contradiction:
Improveantiseptic effectVSAvoidresidue toxicity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A reducing agent is introduced as an intermediary substance that reacts with residual hypochlorite on tissue surfaces to convert it into non-toxic products. The kit contains both the hypochlorite solution and a reducing agent (such as sodium thiosulfate or ascorbic acid) that neutralizes residues after disinfection, eliminating toxic effects while preserving the antiseptic benefit.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention transforms the harmful residue into a recoverable non-toxic state by adding a reducing agent that converts residual hypochlorite into chloride ions and water. This allows the system to discard the harmful oxidizing residue and recover a safe end state, effectively eliminating residue toxicity while maintaining disinfection efficacy.

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If higher concentrations of hypochlorite solutions are used, then disinfection efficacy is improved, but tissue damage risk increases

Engineering Contradiction:
Improvedisinfection efficacyVSAvoidtissue damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The reducing agent serves as a protective intermediary that neutralizes excess hypochlorite that would otherwise damage tissue. By incorporating this neutralizing agent into the kit, high-concentration hypochlorite solutions can be used for effective disinfection without the risk of tissue damage, as the reducing agent converts any excess or residual oxidizing agent into harmless products.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The reducing agent is prepared in advance as a cushioning measure against potential tissue damage. The kit is designed to include both the hypochlorite solution and the reducing agent, allowing the user to first apply the disinfectant and then immediately neutralize any residues before they can cause harm, effectively cushioning against the harmful effects of high-concentration oxidizing agents.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Stability of the object's composition

If solid form active ingredient is used, then storage stability is improved, but dissolution and delivery complexity increases

Engineering Contradiction:
Improvestorage stabilityVSAvoiddissolution system
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The active ingredient is prepared in solid form in advance during manufacturing, which provides superior storage stability and allows for long-term shelf life without degradation. The device includes pre-assembled components (reservoir, filter, connection elements) that are ready for immediate use, eliminating the need for complex preparation steps while maintaining the stability benefits of solid form storage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system is designed to automatically dissolve the solid active ingredient when liquid flows through the reservoir, eliminating the need for manual preparation. The filter automatically retains any undissolved particles, and the connection elements automatically interface with standard containers, making the dissolution and delivery process self-service and minimizing user burden despite the solid form complexity.

Inventive Principle:
Principle #25Self-service
