Power Supply Unit Hook and Stopper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply apparatuses require complex and costly rail structures to prevent units from falling during inspection and repair, necessitating significant time and effort for attachment, which increases costs and complexity.
Innovation Solution
A power supply apparatus with a self-standing housing and units that include a hook portion and stopper mechanism, allowing for easy insertion and removal of units without the need for extensive rail systems, using a hook base and tip portion supported by left and right rails and a stopper with an inclined surface to prevent forward movement and falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rail structure is provided on the inner wall of the housing to hold the unit in a pulled-out state, then the unit can be prevented from falling, but the cost and the number of components increase significantly
Solution Approach 1:
The patent extracts the essential function of the complex rail structure and implements it through a simplified stopper mechanism that engages with a groove on the unit. This removes unnecessary structural elements while maintaining the core function of preventing unit fall during pulled-out state.
Solution Approach 2:
The stopper is designed as a simple, inexpensive component that can be easily manufactured and replaced if needed. It serves as a temporary engagement mechanism that fulfills its purpose during unit installation and removal, then can be discarded or replaced without significant cost.
2Reliability
If a rail structure is provided on the inner wall of the housing to hold the unit in a pulled-out state, then the unit can be prevented from falling, but the attachment time and effort increase
Solution Approach 1:
The patent extracts the essential function of the complex rail structure and implements it through a simplified stopper mechanism that engages with a groove on the unit. This removes unnecessary structural elements while maintaining the core function of preventing unit fall during pulled-out state.
Solution Approach 2:
The unit is segmented with a dedicated groove structure that interfaces with the stopper, separating the stabilization function from the main body. This segmentation allows for easy engagement and disengagement, reducing attachment and removal time.
3Reliability
If a complex rail structure is used to prevent unit fall, then unit stability is improved, but the cost increases
Solution Approach 1:
The stopper is designed as a simple, inexpensive component that can be easily manufactured and replaced if needed. It serves as a temporary engagement mechanism that fulfills its purpose during unit installation and removal, then can be discarded or replaced without significant cost.
Solution Approach 2:

AI summary
A power supply apparatus includes a housing being self-standing and having an opening on a front side, and a unit disposed in the housing to be insertable and removable in a front-back direction through the opening. The unit includes a lower-left slide portion positioned at a left lower end when facing forward from inside the housing, a lower-right slide portion positioned at a right lower end when facing forward from inside the housing, and a hook portion disposed between the lower-left slide portion and the lower-right slide portion. The hook portion includes a hook base portion extending downward, and a hook tip portion extending forward from a lower end of the hook base portion.
