Recording Frame Layout for Upright Transport Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices that are long in two intersecting horizontal directions face stability issues when transported in an upright posture, leading to potential instability and the need for additional stabilization jigs.
Innovation Solution
A recording device design featuring a base frame with intersecting frames and recessed portions that stabilize the device by positioning the center of gravity above a region defined by terminal end portions, allowing it to maintain an upright posture without additional jigs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the recording device is transported in an upright posture to pass through narrow entrances, then the device can be transported through narrow spaces, but the device becomes unstable and easily falls over
Solution Approach 1:
The patent applies dimensionality change by positioning the center of gravity in the vertical direction when the device is in upright posture. The frame structure is designed so that the center of gravity lies within the vertical projection of the contact area with the support surface, converting the stability problem from a horizontal balance issue to a vertical gravitational alignment issue. This allows the device to be transported upright without additional stabilization jigs.
2Stability of the object's composition
If stabilization jigs are added to prevent the device from falling over during transport, then the device stability is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by designing the frame structure itself to provide stabilization. The specific geometric arrangement of the first, second, and third frames creates a center of gravity position that inherently stabilizes the device in upright posture. The device stabilizes itself through its own structure without requiring external stabilization jigs or additional components.

AI summary
A recording device includes a medium moving unit that moves a medium support unit supporting a medium, a recording unit that is caused to perform scanning to perform recording on the medium, a base frame that has a flat plate shape and supports the medium moving unit, and a first middle frame and a second middle frame that are supported by the base frame and disposed in a posture intersecting the base frame. When a terminal end portion located at a terminal end, of the base frame, a terminal end portion located at a terminal end, of the first middle frame, and a terminal end portion located at a terminal end, of the second middle frame are caused to face downward and brought into contact with a horizontal surface, the center of gravity of the recording device is positioned vertically above a region surrounded by the terminal end portions.
