Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing probes for trenchless guide instruments face challenges in maximizing both the size of the antenna and the capacity of the power supply due to fragile magnetic cores leading to energy consumption issues and reduced accuracy, and the trade-off between antenna size and battery capacity in limited space.
Innovation Solution
A probe design with a battery region and electronic region, featuring an antenna with magnetic core units made from nickel steel, positioned on the peripheral surface of an insulating pipe, and a control circuit board inside a metal pipe, allowing for increased antenna size and battery capacity while reducing eddy currents and enhancing vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the magnetic cores are made from high-permeability ferric oxide, then the antenna transmission efficiency is improved, but the magnetic cores are easily cracked after long period of vibration, generating higher energy consumption and reducing probe position accuracy
Solution Approach 1:
The patent changes the material parameter of the magnetic core from high-permeability ferric oxide to nickel steel, which has different mechanical and magnetic properties. This material substitution resolves the contradiction by providing both vibration resistance and acceptable transmission efficiency, as nickel steel maintains structural integrity under vibration while still providing necessary magnetic properties for antenna operation.
Solution Approach 2:
The patent employs composite material structure by combining nickel steel magnetic core units with insulating materials. The magnetic core units are positioned on the peripheral surface of an insulating pipe, creating a composite structure that provides both magnetic functionality and mechanical protection, thereby improving durability while maintaining transmission efficiency.
2Power
If the antenna size is increased to maximize transmission capacity, then the transmission power is improved, but the battery capacity cannot be maximized due to limited space in the drill bit
Solution Approach 1:
The patent implements nested arrangement where the magnetic core units are positioned on the peripheral surface of the insulating pipe, and the coil winds around these magnetic core units. This nested structure allows the antenna to be configured in a space-efficient manner, maximizing transmission power while leaving room for battery installation in the probe compartment.
Solution Approach 2:
The patent transitions from a conventional linear arrangement of components to a radial arrangement where magnetic core units are distributed on the peripheral surface of the insulating pipe. This dimensional change allows the antenna to occupy space more effectively in three-dimensional space, enabling larger transmission power without proportionally increasing the probe length, thus preserving battery capacity space.
3Quantity of substance
If the probe length is extended to accommodate larger battery compartment, then the battery capacity is improved, but the drill bit cannot accommodate the extended probe
Solution Approach 1:
The patent uses nested arrangement where the battery is positioned within the probe compartment in a compact configuration, and the antenna components are nested around the insulating pipe. This nested structure minimizes the overall probe length while maximizing battery capacity, allowing the drill bit to accommodate the probe without requiring excessive extension.
Solution Approach 2:
The patent applies local quality optimization by concentrating the battery in a specific compartment area and arranging the antenna components around the insulating pipe in a localized manner. This localized arrangement maximizes space utilization within the constrained probe dimensions, enabling larger battery capacity without increasing the overall probe length that would not fit in the drill bit.
