Printing Apparatus Center of Gravity Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing apparatus design, where the cutter assembly and ink tank are on the same side, offsets the center of gravity, making it difficult for users to hold and increasing the risk of dropping the device.
Innovation Solution
The printing apparatus is redesigned with the cutter assembly and ink tank positioned on opposite sides, balancing the center of gravity towards the center, improving handleability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cutter assembly and ink tank are arranged on the same side of the printing apparatus, then the structure is simplified and easier to manufacture, but the center of gravity is offset to one side making it difficult for users to hold and increasing the risk of dropping the device
Solution Approach 1:
The patent applies asymmetry by deliberately positioning heavy components (ink tank and cutter assembly) on opposite sides of the printing apparatus. This asymmetric arrangement creates a balanced center of gravity at the geometric center, resolving the contradiction between simplified manufacturing and ease of handling by optimizing the spatial distribution of components.
Solution Approach 2:
The patent uses the counterweight principle by placing the ink tank and cutter assembly on opposite sides of the apparatus. These components act as counterweights to each other, balancing the center of gravity and improving handleability while maintaining structural simplicity through symmetric component placement.
2Volume of moving object
If the cutter assembly and ink tank are arranged on the same side of the printing apparatus, then the device layout is compact, but the center of gravity is offset reducing stability and increasing dropping risk

AI summary
A printing apparatus, having a conveyer configured to convey a recording medium along a first conveying direction, an image recorder to record an image on the recording medium supported by a supporting portion, a liquid storage arranged on an outside of the supporting portion in a direction intersecting with the first conveying direction, a cutter assembly to cut the recording medium, and a controller, is provided. The controller is configured to move the cutter assembly to an outside of the supporting portion in a scanning direction, which intersects with the first conveying direction, to cut the recording medium; and control the cutter assembly to stand by at a standby position located on a side of the supporting portion opposite to the side, on which the liquid storage is arranged, on the other outside of the supporting portion in the scanning direction.
