Resilient Anchor Assembly for Shock and Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor systems fail to effectively absorb shock loads and vibrations, leading to substrate damage and loosening of the anchor, especially in frangible materials like concrete, due to direct force transmission and pre-stressing.
Innovation Solution
An anchor assembly comprising a shell with a resilient member and engagement member, where the resilient member is compressible and positioned between the engagement member and the shell's trailing edge, allowing for the absorption of shock and vibration forces by compressing and pivoting, thereby reducing peak force transmission to the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid expansion bolt is used to securely fasten to the substrate, then the anchor holds the fixing member firmly, but shock loads and vibrations are directly transmitted to the substrate causing cracking and loosening
Solution Approach 1:
The patent changes the mechanical parameter of the anchor body from rigid to resilient/flexible. The resilient anchor body can deform elastically under shock loads and vibrations, absorbing energy while maintaining secure fastening to the substrate, thereby preventing substrate cracking and anchor loosening
Solution Approach 2:
The resilient anchor body acts as an intermediary between the fixing member and the substrate. It mediates the transmission of shock loads and vibrations by deforming elastically, reducing the peak forces transmitted to the substrate while maintaining the anchoring function
2Reliability
If the anchor is pre-stressed against the substrate to ensure secure fastening, then the fixing is firmly attached, but the substrate is at risk of cracking and the anchor may loosen
Solution Approach 1:
The patent changes the mechanical parameter of the anchor body from rigid to resilient. The resilient anchor body maintains sufficient contact pressure with the substrate for secure fastening while being able to deform elastically under additional loads, preventing substrate cracking and maintaining attachment strength
Solution Approach 2:
The resilient anchor body provides beforehand cushioning by being pre-configured with elastic properties. This allows it to absorb sudden shock loads and vibrations before they can cause substrate cracking, while maintaining the necessary pre-stress for secure attachment

Function Achieved in This Case
The anchor assembly effectively reduces shock loads and vibrations transmitted to the substrate, maintaining the anchor's hold and preventing substrate damage, even under impact and seismic conditions.
Implementation Method 1
the resilient member is compressible and positioned between the engagement member and the shell's trailing edge, allowing for the absorption of shock and vibration forces by compressing and pivoting

AI summary
An anchor assembly for receiving a fixing member. The assembly may include a shell with a substrate engagement surface. The shell defines a passage configured to receive the fixing member. The passage extends from a trailing edge end of the shell towards a leading edge end of the shell along an alignment axis. There is also provided an engagement member and a resilient member located in the passage. The resilient member is mounted in the passage such that it is fixed relative to the passage and such that an end of the resilient member is moveable with the engagement member along the passage.
