Elastomer Buffer Stopping Structure for Waterproof Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, such as waterproof cameras, face damage due to non-uniform structural strength under high water pressure, leading to water seepage and loss of waterproof functionality in extreme underwater environments.
Innovation Solution
Incorporating a stopping structure with a buffer, such as an elastomer, between the housing and electronic elements, which absorbs external forces and prevents excessive compression, thereby enhancing pressure resistance and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the electronic device uses a rigid housing structure, then the structural strength is improved, but the device becomes vulnerable to water pressure deformation in extreme environments
Solution Approach 1:
The patent introduces an elastomer buffer between the housing and electronic elements. This elastomer acts as a flexible component that can deform under water pressure to absorb stress, preventing the rigid housing from transmitting excessive force to critical components. The elastomer's flexibility allows the structure to adapt to pressure changes while maintaining waterproof integrity.
Solution Approach 2:
The patent combines rigid housing materials with flexible elastomer materials to create a composite structure. The rigid housing provides overall structural strength, while the elastomer buffer provides pressure resistance and flexibility. This composite approach allows the device to maintain both strength and adaptability to extreme environments.
2Strength
If the housing structure is made uniformly strong, then overall durability is improved, but local structural deformation still occurs under high water pressure
Solution Approach 1:
The patent applies the elastomer buffer specifically at critical locations where electronic elements are positioned, rather than making the entire housing flexible. This localized application allows the housing to maintain uniform rigidity overall while providing targeted flexibility and pressure absorption at vulnerable points, preventing local deformation without compromising overall structural integrity.
3Area of moving object
If the window area is increased for better visibility, then the viewing capability is improved, but the risk of water seepage increases under high pressure
Solution Approach 1:
The elastomer buffer acts as an intermediary between the housing/window structure and the electronic elements behind it. When water pressure acts on the window, the elastomer absorbs and distributes the force, preventing concentrated stress at the window-housing interface. This intermediary layer protects the sealing structure from pressure-induced deformation that could lead to water seepage.

Function Achieved in This Case
The buffer structure effectively absorbs external forces, enhancing the pressure resistance and shock resistance of electronic devices, thereby improving their waterproof functionality and reducing the likelihood of damage from compression.
Implementation Method 1
an elastomer has a hook and a base. The hook is disposed between the first portion and the electronic element, and abuts the first portion

AI summary
An electronic device and a stopping structure thereof are provided. The electronic device includes a housing, an electronic element, a cover and a buffer. The housing has an opening. The electronic element is disposed corresponding to the opening. An outer frame of the cover is coupled to a peripheral edge of the opening. A hook of the buffer is disposed between the outer frame and the electronic element, and directly contacts with the outer frame. Thus, the above structure may strengthen the structural strength of the electronic device, effectively disperse the pressure applied to the electronic device, and reduce the chance of structural damage due to the deformation caused by the pressure to prolong the service life of the electronic device.
