Electronic Component Case With Shutter and Through-Hole for Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component cases have difficulty in efficiently supplying and discharging cleaning liquids due to a single small opening, making it challenging to clean the interior effectively.
Innovation Solution
The case design includes a shutter to open and close a discharge port and a through-hole formation portion in the inner rear wall, allowing for the supply and discharge of cleaning liquids through multiple openings, facilitating easy cleaning and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single small opening is used for component discharge, then the case structure remains simple, but cleaning liquid supply and discharge becomes inefficient
Solution Approach 1:
The case divides the single opening into multiple separate openings: a component discharge opening and a through hole for cleaning liquid supply. This segmentation allows the discharge opening to remain simple for component ejection while the through hole provides dedicated cleaning access, resolving the contradiction between structural simplicity and cleaning efficiency
2Device complexity
If only one opening is provided, then the case design remains simple, but cleaning liquid cannot be supplied and discharged smoothly
Solution Approach 1:
The case separates the component discharge function from the cleaning function by providing distinct openings: the discharge opening for components and the through hole for cleaning liquid. This functional segmentation enables smooth cleaning liquid supply and discharge while maintaining overall design simplicity
Solution Approach 2:
The shutter mechanism acts as an intermediary that controls access to the discharge opening. During cleaning operations, the shutter can be opened to allow cleaning liquid to enter through the through hole and exit through the discharge opening, facilitating efficient cleaning while maintaining a simple case structure

AI summary
A case includes a case body including an accommodation space to accommodate electronic components and a discharge port to accommodate in and discharge the electronic components from the accommodation space, and a shutter slidable in the case body to open and close the discharge port. The case body includes an inner rear wall portion defining the accommodation space. The inner rear wall portion includes a thin portion defining and functioning as a through-hole formation portion at which a through hole may be provided to allow communication between outside of the case body and the accommodation space.
