Anchor Rod Assembly With Multi-Hardness Sleeve for Mortar Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no anchor rod that can be used universally across different synthetic resin mortar systems, including injection systems and composite anchor capsules, due to variations in mortar properties and application conditions.
Innovation Solution
An anchor rod assembly with a shaft section, a fastening section surrounded by a sleeve-like additional element made of different materials for support and tear areas, and a head part with a cutting edge for shredding and mixing mortar components, ensuring effective mixing and separation from the mortar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-material sleeve is used around the fastening section, then the structure is simple, but it cannot provide both support area and tear area with different hardness properties
Solution Approach 1:
The patent applies composite materials by constructing the sleeve from multiple materials with different hardness properties. The sleeve comprises a softer material (e.g., plastic) and a harder material (e.g., rigid foam or metal), creating distinct support and tear areas. This composite structure enables the anchor rod to adapt to different mortar systems while maintaining structural integrity and functionality.
2Adaptability or versatility
If the anchor rod is designed for specific mortar systems only, then the design is optimized for those systems, but it lacks universal applicability across different mortar types
Solution Approach 1:
The patent implements universality by designing the anchor rod with a multi-material sleeve that can function across different mortar systems (radically curing, polyadditively curing, and composite anchor capsules). The sleeve's dual hardness structure provides both support and tear functions that are beneficial regardless of the specific mortar type, making the anchor rod universally applicable while maintaining ease of manufacture through standardized design.
3Strength
If the sleeve material is too hard, then it provides sufficient support, but it cannot tear easily to allow mortar separation
Solution Approach 1:
The patent applies local quality by creating different hardness zones within the sleeve structure. The support area is made of harder material to provide structural strength, while the tear area is made of softer material to enable easy separation. This localized differentiation of material properties allows the sleeve to simultaneously provide both support strength and ease of tear separation in different regions of the same component.
