Rectangular Frame Structure for Flatbed Recorder Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flatbed recording apparatus with a gate-shaped frame portion is prone to deformation, leading to reduced rigidity, movement accuracy, and throughput due to its susceptibility to yawing and high center of gravity, which affects the recording unit's movement controllability and image quality.
Innovation Solution
A recording apparatus with a rectangular frame portion, comprising a horizontal bridging frame, side frames, and a connecting frame that lowers the center of gravity and enhances rigidity, utilizing a combination of rod-shaped and plate-shaped frames for the connecting frame and a linear guide or lead screw mechanism for precise movement, while maintaining cost-effectiveness.

Engineering Contradiction Analysis
1Ease of operation
If the frame portion is formed in a gate shape, then the recording unit can be supported and moved, but the frame portion is easily deformed and has low rigidity
Solution Approach 1:
The frame portion is divided into multiple independent components: a horizontal bridging frame, first and second side frames, and a connecting frame. These segmented parts are assembled to form a complete rectangular frame structure, allowing each component to be optimized for its specific function while collectively providing high rigidity and resistance to deformation.
Solution Approach 2:
The connecting frame is constructed using a composite structure combining rod-shaped frames and plate-shaped frames. This composite configuration provides enhanced rigidity and structural strength compared to using a single material or shape, while maintaining cost-effectiveness through the use of appropriately shaped components for their respective functions.
2Ease of operation
If the frame portion is formed in a gate shape, then the recording unit can be supported, but the center of gravity is high and movement accuracy is reduced
Solution Approach 1:
The frame structure extends in multiple dimensions to form a complete rectangular configuration that surrounds the stage portion. By adding the connecting frame that links the base portions of the side frames, the structure gains dimensional stability and lowers the center of gravity, improving movement accuracy without compromising support capability.
3Ease of operation
If the frame portion is formed in a gate shape, then the recording unit can be supported, but the frame portion is susceptible to yawing and deformation
Solution Approach 1:
The horizontal bridging frame, side frames, and connecting frame are merged into a single integrated rectangular frame structure. This merged configuration provides comprehensive structural stability, resistance to yawing, and deformation suppression while maintaining the support function for the recording unit.

AI summary
A recording apparatus includes a supporting stage, a recording unit, frame portions that bridge a space to cross the supporting stage and support the recording unit, and a Y axis movement unit that causes the recording unit and the frame portions to move in relation to the stage in the Y axis direction. The frame portions include a horizontal bridging frame that crosses the supporting stage and supports the recording unit, a pair of side frames that support both sides of the horizontal bridging frame in the X axis direction by end portion sides thereof, and a connecting frame that connects base portion sides of the pair of side frames to one another.
