Light-Curing Injection Mortar for Fast Temperature-Independent Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical screw anchors require a long time to cure, with curing times significantly dependent on temperature, limiting application and adjustment time, and have limited processing times due to temperature sensitivity.
Innovation Solution
A UV-curing injection mortar with a radiation source positioned within the injection mortar range, using a radiation-activated reactive resin that cures quickly upon exposure to electromagnetic radiation, allowing for rapid adjustment and high stability independent of temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional chemical screw anchors are used, then high firmness is achieved, but curing time is long and temperature-dependent
Solution Approach 1:
The patent replaces the thermal curing mechanism (heat-dependent chemical reactions in conventional anchors) with a radiative curing mechanism (UV or visible light activation). This substitution eliminates temperature dependence and enables rapid curing within seconds to minutes, directly resolving the contradiction between achieving high firmness and reducing curing time
Solution Approach 2:
The patent changes the curing activation parameter from thermal energy to electromagnetic radiation. By using photoinitiators that activate under UV or visible light, the system achieves rapid polymerization independent of temperature, transforming the curing process from a slow, temperature-sensitive reaction to a fast, light-triggered process
2Loss of time
If quick-curing chemical screw anchors are used, then curing time is reduced, but processing time becomes very limited
Solution Approach 1:
The patent applies preliminary action by providing the radiation source in advance within the injection cartridge. The reactive resin and photoinitiator are pre-mixed and ready, but curing is delayed until light activation. This allows the operator to insert the anchor and positioning elements first, then trigger curing only when positioning is complete, eliminating the race between injection and curing
3Strength
If conventional two-component systems are used, then high firmness is achieved, but the system is complex and requires precise mixing
Solution Approach 1:
The patent segments the curing trigger function from the chemical composition itself by incorporating a photoinitiator into the reactive resin. This allows the resin to remain stable in a single-component formulation until activated by light, eliminating the need for separate hardener containers, mixing mechanisms, and dosage control systems required by two-component epoxy anchors
Solution Approach 2:
The patent introduces a photoinitiator as an intermediary substance that bridges the gap between stable storage and rapid curing. This single-component system with photoinitiator adds minimal complexity compared to two-component systems while achieving equivalent or superior firmness through light-triggered polymerization
