Power Supply Adapter Nesting in Compact Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction in size of information processing apparatuses, such as POS terminals, has resulted in limited space on the back surface for disposing input and output terminals, making it difficult to accommodate necessary I/O terminals.
Innovation Solution
The design includes a housing with an accommodation portion for removably accommodating a power supply adapter, allowing the power supply adapter's cables to be routed internally, thereby freeing up space on the back surface for additional I/O terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the housing is reduced in size and thickness, then the information processing apparatus achieves size reduction, but the space on the back surface for disposing I/O terminals becomes insufficient
Solution Approach 1:
The invention relocates the power supply adapter from external placement to an internal accommodation chamber within the housing. The primary-side cable passes through the housing wall to connect externally, while the secondary-side cable connects internally to the circuit board. This dimensional reorganization allows I/O terminals to be freely arranged on the back surface without being occupied by the power supply adapter, resolving the space conflict caused by housing size reduction.
2Area of stationary object
If the power supply adapter is accommodated within the housing, then space on the back surface is freed for I/O terminals, but the housing structure becomes more complex
Solution Approach 1:
The housing is segmented into a main body and an internal accommodation chamber. The power supply adapter is isolated within this dedicated chamber, which is accessible through a removable cover. This segmentation allows the power supply function to be integrated without complicating the overall housing structure, as the adapter can be independently installed, removed, and serviced without affecting other components.
Solution Approach 2:
The power supply adapter is nested within the accommodation chamber formed inside the housing. The chamber walls are formed by the housing structure itself, and the adapter fits within this nested space. The primary-side cable penetrates the housing wall to establish external connection, while the secondary-side cable connects to the circuit board inside the nested chamber, creating a compact integrated structure.
