Concealed Pressure-Adjusting Filter Layout for Charger Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposing an internal pressure adjusting filter on the outer surface of an electronic device unit compromises its design attractiveness.
Innovation Solution
The internal pressure adjusting filter is positioned behind an electronic component, with a hole in the component overlapping the filter, allowing it to be hidden and reducing the need for a separate component to press it, thus maintaining the device's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the internal pressure adjusting filter is disposed on the outer surface of the case, then the pressure adjustment function is achieved, but the design attractiveness of the electronic device unit is impaired
Solution Approach 1:
The internal pressure adjusting filter is nested behind an electronic component (such as a connector or housing element) that is already present in the device. The filter is positioned in a recessed area or behind another component structure, allowing it to be hidden from external view while remaining functional. This nesting approach enables the pressure adjustment function to be integrated into the existing component layout without adding visible external elements.
Solution Approach 2:
An electronic component acts as an intermediary element that conceals the internal pressure adjusting filter. The intermediary component (such as a connector housing or structural element) is positioned between the external environment and the filter, allowing the filter to perform its pressure adjustment function while being hidden from view. This intermediary structure serves dual purposes: maintaining device aesthetics and enabling pressure regulation.
2Shape
If the internal pressure adjusting filter is hidden behind an electronic component, then the design attractiveness is maintained, but the filter may require additional components to ensure proper positioning and pressing
Solution Approach 1:
The electronic component that conceals the filter is designed to serve multiple functions: it acts as a structural element of the device, provides mechanical support and positioning for the filter, and simultaneously conceals the filter from external view. By making the concealing component multi-functional, the need for separate dedicated pressing or positioning components is eliminated, maintaining design attractiveness without increasing overall device complexity.
Solution Approach 2:
The functions of structural support, filter positioning, and aesthetic concealment are merged into a single electronic component design. The component structure is integrated such that its natural positioning and structural features provide the necessary pressing and support for the filter, eliminating the need for additional separate components. This merging approach maintains simplicity while achieving the desired aesthetic and functional goals.

AI summary
An internal pressure adjusting filter (60) is housed in an internal pressure adjusting filter housing portion (25) of a recess (24) of an upper case (20). Consequently, the internal pressure adjusting filter (60) is disposed at a position where it overlaps an upper case hole (23). A main body portion (51) of a bushing member (50) is fitted into the recess (24) of the upper case (20). Consequently, the bushing member (50) is disposed at a position where it overlaps an opening (22) for bushing member and the internal pressure adjusting filter (60). Since the internal pressure adjusting filter (60) is disposed at the back of a bushing member hole (52a) of the bushing member (50), the internal pressure adjusting filter (60) is hidden behind the bushing member (50) and thus can be less conspicuous than in a type in which the internal pressure adjusting filter (60) is disposed on an outer wall of the upper case (20), and as a result, it is possible to prevent the internal pressure adjusting filter (60) from impairing the design attractiveness of a charger (100).
