Boring Element Transmitter Buffering for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earth drilling devices with integrated transmitters often suffer from insufficient reduction of impact loads, leading to transmitter damage during operation.
Innovation Solution
The transmitter is suspended exclusively in a pulling, elastic, damping manner within the drilling element's housing, using a front buffer that allows rearward displacement upon impact without direct contact, and optionally includes a rear buffer for additional damping during high-force events, along with an integrated energy supply and accessible receptacle for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter is firmly mounted in the housing, then the transmitter maintains a defined position, but the impact forces damage the transmitter
Solution Approach 1:
The transmitter is mounted on a buffer element that is pre-installed in the receptacle of the drilling element. This buffer element is designed to deform under impact forces, absorbing and dissipating the shock before it reaches the transmitter. The buffer provides beforehand cushioning by being in place before impact occurs, allowing the transmitter to move slightly relative to the housing during impact events without suffering damage.
2Object-affected harmful factors
If the transmitter is embedded in damping elements, then impact forces are reduced, but the transmitter cannot be easily accessed for maintenance
Solution Approach 1:
The mounting system is segmented into distinct functional components: the buffer element for impact absorption, the receptacle for housing the transmitter, and the housing structure. The buffer element is designed as a separate, replaceable component that can be independently accessed and replaced. The receptacle is designed with an opening that allows the transmitter to be removed and reinstalled without dismantling the entire drilling element, enabling easy maintenance while preserving the buffer's protective function.
3Object-affected harmful factors
If the transmitter is movable in the receptacle, then impact forces are absorbed, but the transmitter position becomes unstable
Solution Approach 1:
The mounting system transitions from a static firm mounting to a dynamic buffered mounting. The buffer element allows the transmitter to move dynamically in response to impact forces, absorbing shock through controlled deformation. During normal operation without impact, the buffer maintains the transmitter in a stable defined position. The system adapts its characteristics based on the operational state: stable during normal use, compliant during impact events.
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
This configuration significantly reduces impact forces on the transmitter, improving durability and location accuracy while allowing for easy maintenance and assembly.
Implementation Method 1
the transmitter in the event of a rear impact on the drilling element undergoes a rearward displacement in the receptacle, made possible by a deformation of the buffer
Implementation Method 2
The transmitter is suspended exclusively in a pulling, elastic, damping manner

AI summary
The invention relates to a boring element of a ground boring device, comprising a housing and a transmitter arranged in a receiving element of the housing, said transmitter being mounted in the receiving element in such a way that it can move in the longitudinal axial direction of the boring element, and is connected to the housing by a front-side buffer in such a way that the transmitter, when there is a rear percussive impulse on the boring element, moves towards the rear in the receiving element, as a result of a deformation of the buffer, without the transmitter coming directly into contact with another part of the boring element.
