Printing Apparatus Board Box Hook and Screw Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses face difficulties in mounting and removing the control board, requiring disassembly of the after-heater unit for maintenance, which complicates the process.
Innovation Solution
A printing apparatus design featuring a base frame with a hook and hole mechanism, combined with a female screw and fixing member, allows for easy mounting and removal of the board box that accommodates the control board, utilizing space efficiently and improving workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the control board is integrated into the after-heater unit, then the structure is compact, but the ease of maintenance deteriorates
Solution Approach 1:
The control board is separated from the after-heater unit and placed in a dedicated board box, creating an independent module that can be accessed and maintained separately without disassembling the after-heater unit, thus resolving the contradiction between structural compactness and ease of maintenance
2Volume of moving object
If the control board is mounted inside the after-heater unit, then space utilization is improved, but the ease of operation deteriorates
Solution Approach 1:
The control board is housed in a separate board box that is independently accessible, allowing maintenance personnel to access the control board without disassembling the after-heater unit, thereby improving ease of operation while maintaining efficient space utilization through dedicated positioning
Solution Approach 2:
The board box acts as an intermediary structure that houses the control board separately from the after-heater unit, providing a dedicated access path that improves operational ease while maintaining compact overall structure

AI summary
A printing apparatus includes a base frame being bridged between a pair of legs and being configured to support a printing unit, and a board box being arranged under the base frame and being configured to accommodate a control board. A hook is provided to any one surface of a lower surface of the base frame and an upper surface of the board box, and a hole engageable with the hook is provided in the other surface. A female screw is formed in any one side surface of a side surface of the base frame and a side surface of the board box, and a fixing member configured to abut against the one side surface is provided to the other side surface. The board box is fixed to the base frame by a male screw screwed into the female screw through intermediation of the fixing member.
