Multi-function Apparatus Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-function apparatus with two locking members results in a larger and more complex locking mechanism, necessitating a space-saving and secure locking solution with fewer components.
Innovation Solution
A multi-function apparatus featuring a rotating locking member that moves between two positions to engage with the body and document cover, preventing simultaneous opening of the image reading unit and document cover, thereby simplifying the locking mechanism and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two locking members are used to prevent simultaneous opening, then security is improved, but device complexity and size increase
Solution Approach 1:
The patent combines two separate locking members into a single locking member that performs both locking functions. The locking member includes a first engagement portion that engages with the printer housing and a second engagement portion that engages with the document cover, eliminating the need for separate locking mechanisms while maintaining security against simultaneous opening.
Solution Approach 2:
The locking member is designed as a multi-functional component that simultaneously provides both the first locking function (preventing image reading unit opening) and the second locking function (preventing document cover opening). This universal component approach reduces overall mechanism complexity while achieving the same security objectives.
2Reliability
If two locking members are used to prevent simultaneous opening, then security is improved, but the apparatus becomes larger in size
Solution Approach 1:
The patent merges two separate locking members into one integrated locking member, thereby reducing the overall volume occupied by locking components. The single locking member with dual engagement portions occupies less space than two separate locking mechanisms would require.
3Reliability
If two locking members are used to prevent simultaneous opening, then security is improved, but the locking unit becomes larger
Solution Approach 1:
The patent combines two locking members into a single locking unit with reduced footprint. The integrated design allows the locking unit to occupy less area while maintaining both locking functions through the dual engagement portions of the single locking member.

AI summary
A multi-function apparatus includes a body, an image reading unit, a document cover and a locking member. The image reading unit is movable between a closed position and an opened position. The document cover is movable between a closed position and an opened position. The locking member is movable to a first position and a second position and includes a first engagement portion and a second engagement portion. In response to a movement of the document cover to the opened position, the locking member moves to the first position and locks the image reading unit to the closed position. In response to a movement of the image reading unit to the opened position, the locking member moves to the second position and locks the document cover to the closed position.
