Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temporary reinforcement materials for cultural relics at archaeological sites, such as cyclododecane and menthol, require on-site heating, are not suitable for temperature-sensitive relics, and can cause damage due to surface tension and residue issues, limiting their effectiveness and application.
Innovation Solution
A liquid temporary reinforcement material composed of menthol and its derivatives, combined with a crystallization inhibitor at less than 50 ppm, which is controllably volatilizable and can be applied at room temperature, avoiding the need for heating and minimizing residue, while maintaining good infiltration and reinforcement capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cyclododecane or menthol is used as temporary reinforcement material, then reinforcement strength is improved, but the material requires heating to melt before application and solidifies quickly, limiting penetration depth and quantity of relics that can be extracted
Solution Approach 1:
The patent changes the physical state parameter of the reinforcement material from solid (requiring melting) to liquid at room temperature. This is achieved by selecting specific compounds with appropriate melting points and using them in a liquid state, eliminating the need for heating equipment and enabling direct application while maintaining reinforcement effectiveness.
Solution Approach 2:
The patent replaces the thermal processing system (heating devices, melting process) with a direct liquid application system. By using compounds that are liquid at room temperature, the mechanical/thermal equipment required for melting is eliminated, simplifying the operational process at archaeological sites.
2Strength
If cyclododecane or menthol is heated and applied as liquid, then reinforcement is achieved, but the material solidifies quickly under low temperature, limiting penetration depth
Solution Approach 1:
The patent modifies the temperature parameter at which the material is applied by selecting compounds that remain liquid at room temperature and low temperatures. This allows the material to penetrate deeper into relics without solidifying prematurely, while still providing effective reinforcement upon controlled solidification or evaporation.
3Ease of operation
If organic solvents are used to dissolve temporary reinforcement materials, then application is easier, but surface tension during volatilization may damage cultural relics and organic solvents may affect the color of relics
Solution Approach 1:
The patent extracts and eliminates the harmful organic solvent component from the reinforcement material system. By using pure compounds that are liquid at room temperature without requiring organic solvents for dissolution, the patent removes the source of surface tension damage and color contamination while maintaining application ease.
Solution Approach 2:
The patent uses volatile compounds that evaporate completely without residue, replacing persistent organic solvents. These materials provide temporary reinforcement and then disappear completely, avoiding long-term harmful effects on the cultural relics while fulfilling their functional purpose.
4Strength
If cyclododecane is used, then reinforcement strength is good and it sublimates completely, but it is a waxy solid requiring heating and melting before use
Solution Approach 1:
The patent changes the melting point parameter of the reinforcement material by selecting compounds with lower melting points that allow them to remain liquid at room temperature. This eliminates the need for thermal processing while preserving the sublimation and reinforcement properties of the material.
5Ease of manufacture
If heating devices are used at archaeological sites, then temporary reinforcement materials can be applied, but it is inconvenient to use in the field
Solution Approach 1:
The patent replaces the thermal processing system (heating devices, power sources, control systems) with a direct liquid application system using room-temperature compounds. This eliminates complex equipment requirements while maintaining the ability to apply reinforcement materials effectively at archaeological excavation sites.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a convenient, effective, and residue-free temporary reinforcement for cultural relics, suitable for various environments and temperature-sensitive items, with improved penetration and ease of use, overcoming the limitations of existing materials.
Implementation Method 1
cyclododecane can sublime completely at room temperature, the existence of a liquid phase can be avoided, thus avoiding possible damage to the relics caused by surface tension on a gas-liquid interface; and there is 'zero' residue after sublimation
Implementation Method 2
a liquid temporary reinforcement material comprising a reinforcement material and a crystallization inhibitor... and the liquid temporary reinforcement material is liquid at room temperature

AI summary
The present invention relates to a liquid-state temporary reinforcing material, a preparation method therefor and an application thereof. The liquid-state temporary reinforcing material comprises a reinforcing material and a crystallization inhibitor; the reinforcing material is selected from molecules of any two or more of menthol, menthone, menthol ester and menthol ether, and the content of the crystallization inhibitor is less than 50 ppm. For the liquid-state temporary reinforcing material of the present invention, the menthol and the derivatives of the liquid-state temporary reinforcing material are integrally mixed together to form the composite material for temporary reinforcing, the composite material being liquid and volatilization-controllable at room temperature. Thus, the temporary reinforcing requirements for extracting cultural relics at an archaeology excavation site may be met, and the material is convenient to use.
