Elastic Sealing Module for Detachable Controller Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable game machines lack waterproof and dustproof designs for outdoor use, allowing foreign matter to enter the device.
Innovation Solution
A replacement module with an exterior portion, a connection portion, a holding portion, and an entering preventing portion configured by an elastic body, which are disposed on the surface opposite to the exterior portion, preventing foreign matter from entering when attached to the electronic apparatus regardless of the usage environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the controller is designed to be detachably attached to the main body device for customized usage, then adaptability is improved, but waterproofness and dustproofness deteriorate
Solution Approach 1:
The patent employs an elastic body (flexible membrane) that covers the connection portions of both the controller and main body device. This flexible film maintains the detachable attachment structure for usage customization while forming a protective barrier that prevents foreign matter from entering the connection interfaces, thus resolving the contradiction between adaptability and protection.
2Ease of operation
If the connection structure allows easy attachment and detachment, then ease of operation is improved, but protection against foreign matter deteriorates
Solution Approach 1:
The elastic body is designed to automatically cover and seal the connection portions when the controller is attached to the main body device, and to retract or open when detached. This self-service mechanism provides protection reliability without requiring additional manual operations, thus maintaining ease of operation while ensuring reliable protection against foreign matter.
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
Effectively prevents foreign matter, such as water and dust, from entering the device, ensuring reliable operation in various environments.
Implementation Method 1
an entering preventing portion that has a ring shape, in which the connection portion and the holding portion are disposed inside, and is configured by an elastic body that prevents foreign matter from entering the connection portion and the holding portion in the attached state

AI summary
A replacement module capable of preventing foreign matter from entering when in an attached state regardless of a usage environment is provided. The replacement module that is replaceably attached to an electronic apparatus includes an exterior portion that constitutes a part of an exterior of the electronic apparatus in an attached state of being attached to the electronic apparatus, a connection portion communicably connected to the electronic apparatus in the attached state, a holding portion that holds the attached state, and an entering preventing portion that has a ring shape, in which the connection portion and the holding portion are disposed inside, and is configured by an elastic body that prevents foreign matter from entering the connection portion and the holding portion in the attached state. The connection portion, the holding portion, and the entering preventing portion are disposed on a surface facing a side opposite to the exterior portion.
