Recording Apparatus with Movable Medium Support and Conductive Resin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face deformation issues due to differences in volume changes between the medium support portion and the base portion caused by environmental changes like moisture, leading to distorted images and interference, which current configurations struggle to adequately address.
Innovation Solution
The recording apparatus features a medium support portion that is movable along the support surface and biased in a direction intersecting it, allowing for adjustment to minimize deformation, and incorporates conductive resin to prevent paper powder adhesion, while the base portion does not contain conductive resin to reduce manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If different materials are used for the medium support portion and base portion to reduce paper powder adhesion, then the influence of paper powder is reduced, but the deformation of the medium support portion increases due to volume change differences caused by environmental changes
Solution Approach 1:
The base portion is divided into a first base portion and a second base portion with different materials. The first base portion (contacting medium support portion) uses a material with low paper powder adhesion, while the second base portion (not contacting) uses a different material, creating local quality differences to simultaneously address paper powder issues and structural stability
Solution Approach 2:
The base portion employs a composite structure combining two different materials (first base portion and second base portion) with different volume change characteristics. This composite construction allows the system to benefit from the low adhesion properties of one material while compensating for deformation through the complementary properties of the other material
2Stability of the object's composition
If the medium support portion is made movable to adjust deflection, then deformation can be compensated, but the device complexity increases
Solution Approach 1:
The medium support portion is designed to be movable relative to the base portion, transitioning from a fixed to a dynamic configuration. This mobility enables automatic adjustment of deflection to compensate for volume changes caused by environmental variations, while the simplicity of the movement mechanism keeps added complexity minimal

AI summary
A recording apparatus includes a recording head, a medium support portion which supports, at a support surface, a recording medium in a recording region by the recording head, and a base portion to which the medium support portion is attached in a state of being movable in a direction toward the support surface while being biased in a direction intersecting the support surface.
