Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers require separate members and optional units for additional functions, increasing material and manufacturing costs and management complexity.
Innovation Solution
A printer design with a detachable cover structure that supports optional units, allowing them to be attached in any direction and featuring a deviation suppressing mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optional units (cutting, peeling) are provided as separate attachable components, then functional versatility is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The cover portion is designed to serve multiple functions: it acts as both a protective cover and a mounting structure for optional units. The supporting portion integrated into the cover allows cutting units, peeling units, and other optional components to be attached without requiring separate mounting structures, thereby reducing overall device complexity while maintaining functional versatility.
Solution Approach 2:
The patent combines the cover structure and the mounting structure into a single integrated component. The supporting portion is formed as part of the cover portion itself, eliminating the need for separate mounting brackets or attachment mechanisms. This merging reduces the number of parts and simplifies the overall device structure.
2Adaptability or versatility
If additional components are prepared separately for optional functions, then functional adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The cover portion is designed as a universal mounting platform that can accommodate various optional units (cutting, peeling, etc.) through its integrated supporting portion. This eliminates the need to manufacture separate mounting structures for each optional function, reducing manufacturing costs while maintaining adaptability.
Solution Approach 2:
By merging the cover and mounting structures into a single component, the patent reduces the total number of parts that need to be manufactured, assembled, and managed. This integration simplifies the supply chain and reduces manufacturing costs associated with producing and inventory-managing multiple separate components.
3Adaptability or versatility
If additional components are prepared separately for optional functions, then functional versatility is improved, but management complexity increases
Solution Approach 1:
The integration of the supporting portion into the cover reduces the number of separate components that need to be tracked, stored, and assembled. Service personnel only need to manage the cover assembly as a single unit rather than coordinating multiple separate mounting components, thereby simplifying maintenance and service management.
4Ease of operation
If detachable cover structure is used for optional units, then ease of installation is improved, but structural complexity increases
Solution Approach 1:
The cover is designed as a detachable component that can be easily removed and reattached, allowing optional units to be installed or removed without disassembling the entire device. This segmentation provides ease of installation while the integrated supporting portion minimizes the added structural complexity.

AI summary
A printer includes: a paper holding unit holding a roll paper; a printing unit printing on the paper pulled out from the paper holding unit; and a box-shaped casing housing the paper holding unit and the printing unit, the casing includes: a plate-shaped cover portion; and a main body portion being a portion other than the cover portion, wherein, in an attaching structure in which the cover portion is detachably attached to the main body portion, the cover portion can be attached in any direction where one of a first surface being one surface of the plate-shaped cover portion and a second surface being the other surface in a direction faces the main body portion, and the cover portion has a supporting portion detachably supporting an optional unit performing a predetermined process on the paper in any one of the first surface or the second surface.
