Rotating Window Motor Extraction and Magnetic Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating windows on CNC machine tools and ships have a motor located at the center, obstructing the view and posing safety risks due to the motor's large circular area, which blocks vision and can lead to the window being ruptured and thrown out if objects collide with it.
Innovation Solution
A rotating window design with a magneto-conductive element and a magnet ring that creates an air gap, allowing the window to be absorbed magnetically when damaged, and a support bracket that reduces the motor's footprint, enabling a wider viewing angle and improved safety by preventing the window from being thrown out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor is located at the center of the rotating glass, then the rotating window can be driven effectively, but the motor and housing member block the line of vision and reduce the viewable area
Solution Approach 1:
The motor is extracted from the center of the rotating glass and relocated to a fixed position on the frame. This separates the driving function from the rotating glass, eliminating the visual obstruction caused by the central motor and housing while maintaining effective motor-driven rotation of the glass through the transmission mechanism.
2Device complexity
If the motor is located at the center of the rotating glass, then the driving mechanism is simplified, but the circular rotating glass occupies transparent area and blocks the line of vision
Solution Approach 1:
The motor is extracted from the rotating glass and fixed to the frame. The driving function is maintained through a transmission mechanism (belt, chain, or gear) that connects the fixed motor to the rotating glass, thereby reducing visual obstruction while preserving the simplicity of the driving mechanism.
Solution Approach 2:
A transmission mechanism acts as an intermediary between the fixed motor and the rotating glass. This intermediary component transmits rotational force from the motor to the glass without requiring the motor to be located at the glass center, thus maintaining mechanical simplicity while improving visual access.
3Stability of the object's composition
If the rotating glass is fixed to the frame, then the structure is stable, but if the glass is damaged it will be thrown out and hurt people
Solution Approach 1:
A safety net is installed behind the rotating glass to catch and contain glass fragments in case of rupture. This preventive measure is positioned in advance to intercept harmful debris before it can reach operators, thereby maintaining structural stability while mitigating safety hazards from potential glass failure.
Solution Approach 2:
The safety net converts the harmful effect of glass rupture into a controlled containment scenario. By positioning the net to receive falling glass fragments, the system transforms a potentially dangerous situation into a managed event where debris is captured and prevented from causing injury.
4Reliability
If a non-transparent housing member is fixed at the inner side of the rotating glass, then the motor is protected, but the housing member blocks the view and reduces transparency
Solution Approach 1:
The housing member is extracted from the inner side of the rotating glass and relocated to the frame where the motor is mounted. This separation removes the non-transparent housing from the viewing path, eliminating the blockage to the line of vision while the motor remains protected within the frame structure.
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
The design provides a broader transparent area for observation, reduces the risk of injury by preventing the window from being thrown out, and enhances safety by allowing the window to be absorbed magnetically when damaged, thus minimizing hazards.
Implementation Method 1
coil seats (22), which are wound by a plurality of metallic coils (221), and are fixedly connected in an interior of a magneto-conductive element (20)... An outer diameter of the shaft hole (161) can be largely decreased... the magneto-conductive element (20) forms a motor stator to result in an electro-magnetic field to drive the magnet ring (32) to rotate
Implementation Method 2
in case that the rotating window is damaged, an air gap between a magnet ring and a magneto-conductive element will disappear, enabling an entire frame to be absorbed magnetically to an inner wall of the magneto-conductive element, without being thrown out

AI summary
A rotating window includes a circular base member, a transparent window, and a magneto-conductive element, which are assembled into an electric motor device. By this rotating window, area of transparent region of the transparent window is increased, an outer diameter of a central shaft hole is decreased, and a support bracket is designed as an I-shape or a half I-shape, thereby largely decreasing barriers to the transparent window, allowing a user to conveniently see through scenery or objects at one side of the transparent window without a dead angle. In case that the rotating window is hit by objects and rotates eccentrically, an air gap of the motor disappears, and an entire frame of the rotating window will be absorbed magnetically to the magneto-conductive element, thereby improving safety to people and objects.
