Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location technologies face challenges in accurately determining the depth of hidden location objects, such as reinforcement iron, especially when objects have unexpected dimensions or are arranged closely together, and when systematic errors occur due to nearby metallic objects.
Innovation Solution
A location system utilizing a first inductive location sensor and a second radar or capacitive location sensor, along with a computing unit, to determine and correct object depth measurements. The computing unit processes location characteristics from both sensors to achieve precise depth determination and compensate for systematic errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single inductive location sensor is used to determine object depth, then the device structure remains simple, but measurement precision deteriorates when objects have unexpected dimensions or are arranged closely together
Solution Approach 1:
The patent combines two different location sensors (first location sensor using inductive principle and second location sensor using radar or capacitive principle) into a single location device. The computing unit processes location parameters from both sensors to determine object depth, thereby improving measurement precision while maintaining relatively simple device structure through integrated design
2Device complexity
If a single location sensor is used, then the device complexity is low, but reliability deteriorates when systematic errors occur due to nearby metallic objects
Solution Approach 1:
The patent introduces a second location sensor that operates on a different principle (radar or capacitive) as an intermediary verification mechanism. When the first inductive sensor encounters systematic errors from nearby metallic objects, the second sensor provides alternative measurement data that the computing unit uses to correct or verify the object depth determination, thereby improving reliability
3Measurement precision
If multiple location sensors operating on different principles are used, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The computing unit is designed with multi-functionality to handle location parameters from different sensor types (inductive, radar, capacitive). It can process data from either sensor independently or in combination, determining object depth through various methods including direct measurement, correction using positioning parameters, and verification against expected object properties, thereby managing complexity through unified processing architecture

Implementation Method 3
a second radar or capacitive location sensor
Implementation Method 4
a second radar or capacitive location sensor
