Telescopic Support Tube for Portable Magnetic Field Detector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable magnetic field detectors are bulky and difficult to transport due to their design, with battery compartments hindering optimal shortening and requiring increased work for preparation and restart, and electronic units are often permanently connected with fixed display orientations.
Innovation Solution
A portable search device with a telescopic support tube, a wireless and detachable electronic unit with a pivotable screen, and a hinged battery compartment that can be easily pivoted for transport, allowing quick assembly and disassembly for secure and reliable electrical connections, and adjustable display orientation for ergonomic use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the support tube is made long to accommodate the magnetic field probe, then the device can function properly, but it becomes bulky and difficult to transport
Solution Approach 1:
The support tube is divided into multiple telescopic sections that can be extended when needed and retracted for compact storage, allowing the device to maintain full operational length during use but compact size during transport
Solution Approach 2:
The support tube transitions from a static long structure to a dynamic telescopic structure that can change its effective length, being extended during measurement operations and collapsed during transportation to resolve the contradiction between functional length and transport compactness
2Device complexity
If the battery compartment is attached to the support tube, then power supply is integrated, but it hinders optimal shortening of the support tube for transport
Solution Approach 1:
The battery compartment is separated from the main support tube structure and mounted on a detachable bracket, allowing it to be removed or repositioned independently when the support tube needs to be collapsed for transport
Solution Approach 2:
The battery compartment is extracted from the integrated support tube design and placed on a separate detachable mounting bracket, enabling the support tube to be shortened for transport while the battery compartment can be removed or positioned separately to avoid interference
3Stability of the object's composition
If the electronic unit is permanently connected to the support tube, then structural stability is improved, but adaptability and ease of transport are reduced
Solution Approach 1:
The electronic unit is separated from the permanent structure and mounted on a detachable bracket system, allowing it to be securely attached during operations and easily removed or repositioned for transport scenarios
Solution Approach 2:
The electronic unit mounting transitions from a permanent fixed connection to a dynamic detachable bracket system that provides structural stability during use but allows easy reconfiguration and removal for transport, resolving the contradiction between stability and adaptability
4Ease of manufacture
If the display means has a fixed orientation, then manufacturing is simplified, but ergonomic adaptability is reduced
Solution Approach 1:
The display means is mounted on an articulated mechanism that allows it to be fixed in a simple orientation during manufacturing while enabling dynamic adjustment to multiple orientations during use, providing both manufacturing simplicity and ergonomic adaptability
