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

VSEngineering 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

Engineering Contradiction:
Improvelength of support tubeVSAvoidease of transport
Core Design Contradiction:
Length of moving objectVSEase of operation

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveintegration of battery compartmentVSAvoidease of shortening for transport
Core Design Contradiction:
Device complexityVSEase of operation

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability for transport
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #15Dynamics

4Ease of manufacture

If the display means has a fixed orientation, then manufacturing is simplified, but ergonomic adaptability is reduced

Engineering Contradiction:
Improvesimplicity of display assemblyVSAvoidergonomic adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

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

Inventive Principle:
Principle #15Dynamics
