Solution Overview

Problem

Existing solutions for protecting items in storage from moisture, such as desiccants, are inefficient, costly, and impractical, as they either fail to predict moisture needs or are cumbersome and destructive, while also lacking longevity, and do not effectively prevent fungal growth, corrosion, and insect infestation.

Innovation Solution

Diphenyl tablets are compressed using a tableting machine to create a solid form that releases diphenyl vapor, inhibiting fungal growth, preventing corrosion, and repelling insects and rodents, with the option to include additional ingredients for enhanced performance and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If desiccant packets are used to protect items from moisture, then moisture absorption capacity is improved, but device complexity and ease of operation worsen due to unpredictable weather conditions requiring excessive or insufficient quantities

Engineering Contradiction:

Improvemoisture absorption capacityVSAvoidadaptability to varying weather conditions

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent changes the functional mechanism from passive moisture absorption to active vapor release by transforming the desiccant material into compressed tablets that sublime diphenyl vapor. This parameter change allows the protection mechanism to work independently of environmental humidity levels, providing consistent protection across varying weather conditions without requiring adjustment of quantity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs disposable compressed tablets containing diphenyl mixed with an extrusion agent. These tablets are designed to be replaced rather than regenerated, providing long-term protection (months to years) through continuous slow release of diphenyl vapor. The tablets are inexpensive to manufacture and replace, making them economically viable for long-duration protection applications

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Quantity of substance

If calcium chloride is used as a desiccant, then moisture absorption is improved, but object-generated harmful factors worsen due to formation of messy, viscous, and corrosive liquid brine solution

Engineering Contradiction:

Improvemoisture absorption capacityVSAvoidcorrosive liquid brine solution

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent utilizes phase transition by mixing diphenyl with an extrusion agent that allows the formulation to be extruded into tablets. The diphenyl component then undergoes sublimation (solid to vapor transition) to release protective vapor, avoiding the formation of liquid brine solutions that cause corrosion and mess

Inventive Principle:

Principle #36Phase transitions

Solution Approach 2:

The patent converts the potential harm of moisture interaction into a benefit by using diphenyl vapor that actively protects against moisture-related damage. Instead of creating harmful liquid solutions, the system releases vapor that inhibits fungal growth and prevents corrosion, transforming the interaction with the protected environment from harmful to beneficial

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Quantity of substance

If air conditioning is used to protect items from moisture, then moisture control is improved, but use of energy worsens due to inefficient and costly cooling operations

Engineering Contradiction:

Improvemoisture control effectivenessVSAvoidenergy consumption for cooling

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical cooling system (air conditioning) with a chemical vapor release system. Compressed tablets containing diphenyl slowly sublime vapor that provides protection without requiring energy input for cooling. This substitution eliminates the need for continuous energy consumption while maintaining protection effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The compressed tablets are self-service in that they automatically release diphenyl vapor through sublimation without requiring external energy input or control systems. The tablets independently provide protection over extended periods, eliminating the need for energy-consuming monitoring and control infrastructure required by active cooling systems

Inventive Principle:

Principle #25Self-service

AI summary

A method for making diphenyl tablets includes compressing diphenyl crystals. The diphenyl tablets produced from the method can be used to inhibit fungal growth, repel and/or kill insects and rodents, and/or prevent corrosion in a space by placing the diphenyl tablets into the space such that diphenyl vapor permeates into the space.
