Anchoring device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anchoring devices with exposed anchor bodies face corrosion issues, especially in harsh subsoil conditions near roads with heavy traffic and salt, and are limited to handling pressure and tension forces, with higher deformations occurring under torque and shear forces.
Innovation Solution
The anchoring device features a block of cast material with multiple threads formed within the anchor body, providing secure anchoring, weather protection, and flexible fastening options, allowing for height adjustment and improved resistance to deformations through the use of precast blocks and threaded sleeves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the anchor body is exposed to the weather, then the anchoring device can be installed, but corrosion occurs especially in harsh environments
Solution Approach 1:
The patent applies preliminary action by pre-encasing the anchor body in a protective housing before installation. The housing is prepared in advance with corrosion-resistant properties, and the anchor body is inserted into this pre-prepared protective structure, eliminating the need for post-installation protection measures.
Solution Approach 2:
The patent introduces a housing as an intermediary element between the anchor body and the external environment. This housing acts as a mediator that protects the anchor body from direct contact with corrosive weather elements while still allowing the anchoring function to operate effectively.
2Adaptability or versatility
If the anchor body has only one attachment option, then the structure is simple, but the device can only handle pressure and tension forces
Solution Approach 1:
The patent implements multi-functionality by equipping the housing with multiple attachment options including threaded rods, nuts, and various fastening devices. This allows the same anchoring device to handle diverse force types including pressure, tension, torque, and shear forces, making it universally applicable to different loading conditions.
Solution Approach 2:
The patent applies segmentation by dividing the attachment system into multiple independent components within the housing. Instead of a single attachment point, the housing contains multiple threaded openings and fastening locations that can be used independently or in combination, allowing flexible adaptation to different force requirements.
3Strength
If threaded rods are screwed into threads in the anchor body, then the anchoring device can be assembled, but higher deformations occur under torque and shear forces
Solution Approach 1:
The patent applies the nesting principle by placing the anchor body inside the protective housing. The threaded rods and fastening devices are nested within the housing structure, which provides additional structural support. This nested arrangement distributes loads more effectively and reduces deformations under torque and shear forces compared to exposed threaded rods.
