Air Supply Control for 3D Measuring Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial machines, such as three-dimensional measuring machines, continuously release air during standby periods, leading to wasteful energy consumption, as they maintain air supply even when not in use.
Innovation Solution
An industrial machine equipped with an electromagnetic valve controlled by a controller to block air supply when the machine has been stationary for a preset time, preventing unnecessary air release and allowing quick resumption of operation with an operation directive signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If air is continuously supplied to the drive mechanism during standby state, then the machine can quickly react when operated, but air is wastefully released leading to energy consumption
Solution Approach 1:
The air supply system dynamically adjusts its state based on operational needs. The electromagnetic valve switches between open and closed states, allowing the system to transition between continuous air supply (during operation) and blocked air supply (during standby), optimizing both response speed and energy efficiency
Solution Approach 2:
The controller predicts future operational needs by monitoring the standby duration. When the standby time exceeds a predetermined threshold, the system proactively closes the electromagnetic valve to stop air supply, preparing for energy savings while maintaining the capability for quick resumption when operation is requested
2Use of energy by moving object
If air supply is blocked during standby state, then energy is saved by reducing air release, but the machine cannot quickly return to operational state
Solution Approach 1:
The system implements feedback control through the controller that monitors operational status and standby duration. When an operation request is detected during standby, the controller immediately opens the electromagnetic valve to resume air supply, ensuring quick return to operational state while maintaining energy savings during extended standby periods
Solution Approach 2:
The electromagnetic valve provides dynamic control of air supply, allowing the system to quickly transition from blocked (standby) to open (operational) state when needed, resolving the contradiction between energy saving and quick response capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces air wastage during standby periods, promoting energy savings and enabling rapid return to operational state without initializing the machine or air supplier.
Implementation Method 1
an electromagnetic valve provided inside an air supply passage to open and close the air supply passage
Implementation Method 2
a movement mechanism is moved by a drive force supplied from a drive source... driving resistance is reduced by pumping air from an air supplier to air bearings

AI summary
A three-dimensional measuring machine (industrial machine) includes an air supplier supplying air; a drive mechanism driven by the air supplied from the air supplier; an electromagnetic valve provided inside an air regulator set to open and close an air supply passage inside the air regulator set, the air regulator set introducing the air from the air supplier to the drive mechanism; and a motion controller controlling the electromagnetic valve to block the air supply passage when a time since the drive mechanism stopped operation reaches a preset time.
