Recording Device Frame Structure for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large format inkjet printers require a wide installation space and have insufficient mechanical strength due to their design, which complicates design aesthetics and functionality.
Innovation Solution
A recording device with a frame structure that includes a lower frame, side frames, and a base frame, where the side frames are fixed to the lower frame and extend upright, providing additional support and rigidity, and the base frame holds functional components, allowing for a compact design while maintaining mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the recording device uses a conventional design with roll bodies disposed in front and rear of the leg portion, then the device can hold and transport recording media, but the installation space becomes large due to increased size in front and rear directions
Solution Approach 1:
The patent repositions the roll bodies from a front-rear arrangement to a left-right arrangement relative to the leg portion. The first roll body is disposed to the left and the second roll body to the right of the leg portion, changing the spatial dimension in which the components are arranged. This dimensional change reduces the front-rear length of the device while maintaining all necessary functions, thereby reducing installation space requirements.
2Shape
If the device is formed as a rectangular parallelepiped housing with components accommodated inside, then the appearance becomes more regular, but the mechanical strength is reduced due to insufficient frame rigidity
Solution Approach 1:
The patent employs a composite frame structure combining multiple materials with different properties. The side frames are made of a material with high rigidity modulus, while the leg portion uses a material with high strength. This composite approach allows the housing to have a regular rectangular parallelepiped shape while maintaining excellent mechanical strength and rigidity through the strategic selection and combination of materials with complementary properties.
3Strength
If the side frame is extended downward to improve mechanical strength, then the frame rigidity increases, but the device size increases and design properties deteriorate
Solution Approach 1:
The patent applies local quality by making the side frames extend in the vertical direction with a specific configuration. The side frames have a first section extending vertically from the leg portion and a second section that extends in the front-rear direction, creating an L-shaped structure. This localized structural enhancement provides the necessary rigidity support exactly where needed without requiring an overall extension of the frame that would increase device size and compromise design properties.
