Printer Partition Wall Waterproofing Layout

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing printers lack effective waterproofing of internal components when the housing is opened, and they have a large size due to the layout of the control substrate and battery storage, which affects stability and placement of the center of gravity.

Innovation Solution

A printer design with a partitioned housing that separates the control substrate and battery storage vertically, while the medium storage chamber is positioned to open externally, ensuring waterproofing and reducing the overall size by optimizing the layout to minimize vertical and horizontal dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the opening/closing lid is provided to expose the medium storage chamber to the outside, then the operator can easily insert and replace the print-receiving medium, but spray from the outside may adversely affect the control substrate in the housing interior

Engineering Contradiction:

Improveease of medium insertion and replacementVSAvoidspray affecting control substrate

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The housing interior is divided into a first area containing the control substrate and a second area containing the medium storage chamber, separated by a partition wall. This segmentation isolates the control substrate from spray exposure while maintaining easy access to the medium storage chamber through the opening/closing lid.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A partition wall acts as an intermediary barrier between the medium storage chamber and the control substrate. This partition wall prevents spray from reaching the control substrate while allowing the system to maintain its functional layout with easy medium access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If the control substrate and battery storage part are arranged horizontally for convenience of handling and assembly, then the components are easy to assemble, but the housing size increases and stability decreases

Engineering Contradiction:

Improveease of handling and assemblyVSAvoidhousing horizontal dimension

Core Design Contradiction:

Ease of manufactureVSLength of stationary object

Solution Approach 1:

The control substrate and battery storage part are arranged vertically instead of horizontally, transitioning from a horizontal layout to a vertical layered structure. This dimensional change reduces the housing horizontal dimension and improves stability while maintaining assembly convenience through vertical stacking.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

This disclosure discloses a printer configured to perform desired printing, comprising a substantially box-shaped housing, a partition wall that partitions an internal structure of the housing into a first area positioned on a first side, and a second area positioned on a second side opposite to the first side, a control substrate provided to the first area, a medium storage chamber configured to store the print-receiving medium and provided to the second area, an opening/closing lid configured to expose the medium storage chamber to the outside and provided to the housing and configured to open and close between an open position and a closed position, and a print processing mechanism configured to perform desired printing while feeding the print-receiving medium supplied from the medium storage chamber based on control by the control substrate.
