Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveying technologies face challenges in easily and flexibly exchanging different types of survey markers on existing measuring bolts, especially in harsh environments like tunnels where stability and precision are critical.
Innovation Solution
A device comprising a mounting disc with a disc body for receiving a surveying mark and a plug-in socket for attaching to a measuring pin, featuring a connecting structure with fastening elements to ensure a secure and robust connection, allowing for easy exchange of survey markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standardized measuring bolt is permanently mounted to the object and the survey marker is attached to this bolt, then the survey marker can be securely fixed, but the exchange of different types of survey markers becomes difficult and time-consuming
Solution Approach 1:
The device segments the surveying system into three independent components: the measuring pin (attached to the object), the mounting disc (attachment device), and the surveying mark (marker). This segmentation allows the surveying mark and mounting disc to be exchanged as a unit while the measuring pin remains permanently fixed, enabling quick marker changes without removing the pin from the object.
Solution Approach 2:
The mounting disc serves as a universal interface that can accommodate different types of surveying marks (prisms, panels with reflectors, etc.) while maintaining a standardized connection to the measuring pin. This multi-functionality allows various marker types to be exchanged on the same pin without requiring different mounting mechanisms.
2Reliability
If the surveying mark is securely fixed to withstand high wind speeds, then measurement stability is improved, but the complexity of the attachment mechanism increases
Solution Approach 1:
The invention extracts the complex fastening mechanism from the permanent structure by using a removable mounting disc with integrated fastening elements. The measuring pin itself remains simple and permanent, while the disc with its fastening elements can be attached and removed as needed, providing secure fixation without permanently complicating the pin structure.
Solution Approach 2:
The mounting disc with its fastening elements nests onto the measuring pin, creating a compact hierarchical structure. The disc body receives the surveying mark, while the plug-in socket on the disc nests over the pin, and the fastening elements nest within the connecting structure, achieving secure fixation in a space-efficient manner.
3Strength
If a plug-in socket encloses at least part of the measuring pin, then the connection is made more robust, but the device dimensions increase
Solution Approach 1:
The plug-in socket is designed with dynamic adaptation capabilities through the elastically deformable element that can adjust to variations in pin diameter and surface irregularities. This allows the socket to maintain sufficient engagement length for robust connection without requiring excessive overall length, as the elastic element compensates for dimensional variations.
