Door-equipped housing with flexible hook for thin box body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for thinner box bodies in door-equipped housings while maintaining the ability to stably keep the door closed and facilitate smooth opening and closing operations.
Innovation Solution
A door-equipped housing design featuring a box body with a projecting portion and a door with a hook portion and a flexible part that bends to engage the projecting portion, allowing the door to stably close and smoothly open and close, even when the box body is thinned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the box body is thinned, then the device becomes more compact and lighter, but the door can no longer stably keep closing the opening
Solution Approach 1:
The door assembly is segmented into distinct functional components: a hook portion for engagement, a flexible part for movement, and a support portion for mounting. This segmentation allows each component to be optimized independently, enabling the hook to engage with the projecting portion while the flexible part accommodates the thinned box body geometry.
Solution Approach 2:
The flexible part extends in a direction away from the wall surface having the projecting portion, utilizing the depth dimension of the box body. This dimensional arrangement allows the flexible part to bend and climb over the projecting portion without requiring increased box body thickness, maintaining door closure stability in a thinned configuration.
2Volume of moving object
If the box body is thinned, then the device becomes more compact, but the door opening/closing operation becomes difficult
Solution Approach 1:
The flexible part is designed to be dynamically deformable, bending during the door opening/closing operation to climb over the projecting portion. This dynamic behavior allows the door to move smoothly through the limited space available in a thinned box body, maintaining ease of operation despite reduced dimensions.
Solution Approach 2:
The flexible part acts as an intermediary element between the hook portion and the projecting portion. During door operation, the flexible part temporarily deforms to navigate around the projecting portion, facilitating smooth transition between closed and open states in the constrained geometry of a thinned box body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables stable door closure and facilitates smooth opening and closing operations, compatible with reduced box body thickness, improving design and functionality, such as in coverings for USB ports or external storage medium insertion ports.
Implementation Method 1
a flexible part extending in a direction away from the wall surface having the projecting portion formed thereon as the door closes the opening, and the flexible part bends together with a movement of the hook portion to climb over the projecting portion during an opening/closing operation of the door

AI summary
A door-equipped housing includes a box body having an opening formed on one side thereof, and a door to close the opening, the door being supported by the box body to be rotatable about a rotational axis. The box body has a projecting portion formed on an inside of a wall of the box body extending from the opening toward a deep side of the box body. The door includes a hook portion to engage the projected portion for preventing the door from opening, the hook portion being located on a deeper side of the box body than the projecting portion as the door closes the opening, and a flexible part extending in a direction away from a surface of the wall having the projected portion formed thereon as the door closes the opening. The flexible part bends together with a movement of the hook portion to climb over the projecting portion during an opening/closing operation of the door.
