Solution Overview

Problem

Current geolocation systems for controlling portable tools in industrial settings do not effectively inform users about the position and shape of control spaces, making it difficult for users to easily perceive and define these boundaries, leading to potential misuse of tools outside authorized areas.

Innovation Solution

A system that uses a portable device with a camera and display means to visualize control spaces by projecting or displaying their boundaries in real-time on a screen, allowing users to see the real-world environment with graphic representations of control space boundaries, enabling easy definition and modification of these spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If geolocation systems are used to control tool operation in authorized areas, then tool misuse outside authorized areas is prevented, but users cannot easily perceive or define control space boundaries

Engineering Contradiction:
Improvetool operation controlVSAvoidcontrol space perception
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses color-coded graphic frontiers (e.g., red, yellow, green zones) to represent different control space boundaries and authorization levels. These visual color indicators allow users to immediately perceive their location relative to authorized areas, solving the problem of invisible control space boundaries while maintaining reliable tool operation control.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces a camera-based visualization system as an intermediary between the geolocation system and the user. The camera captures the real environment and overlays graphic frontiers representing control space boundaries, making the invisible geolocation data visible and interpretable for users without adding complexity to the core geolocation control mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If control spaces are defined using coordinates in a reference frame, then precise tool location control is achieved, but users have difficulty visualizing and defining these spaces

Engineering Contradiction:
Improvetool location controlVSAvoidcontrol space definition
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a visual copy of the control space boundaries by projecting graphic frontiers that represent the coordinate-defined control spaces. Instead of requiring users to work directly with abstract coordinates, the system renders these coordinates as visual overlays on the camera image, allowing users to see and define control spaces intuitively while maintaining precise coordinate-based control in the background.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transforms the abstract three-dimensional control space defined by coordinates into a two-dimensional visual representation on the camera image plane. This dimensional transformation allows users to perceive and define control spaces through familiar 2D image interaction while the system maintains precise 3D spatial control through coordinate calculations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If battery-powered screwdrivers are used to improve ergonomics, then cable clutter is eliminated, but tools can be moved to unauthorized areas and misused

Engineering Contradiction:
ImproveergonomicsVSAvoidtool authorization control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements real-time feedback by continuously monitoring the tool's location through geolocation and displaying graphic frontiers that indicate whether the tool is within authorized control spaces. The system provides immediate visual feedback to users about their location status, allowing ergonomic mobile operation while maintaining reliable authorization control through continuous location verification.

Inventive Principle:
Principle #23Feedback
