Solution Overview

Problem

Conventional electronic devices are not adequately designed to withstand hazardous environmental conditions, often suffering damage from moisture, dirt, dust, and water due to insufficient sealing of moving parts and openings, and existing waterproof solutions are bulky, expensive, or limited to specific device models.

Innovation Solution

A flexible, waterproof cover and seal assembly with a connector mechanism that forms a watertight and airtight enclosure for electronic devices, accommodating various shapes and configurations, using a base, washer, and nut system to securely seal around the device's lens and provide adjustable sealing pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional electronic devices are used without specialized waterproofing, then they remain lightweight and compact, but they suffer damage from moisture, dirt, dust, and water due to insufficient sealing of moving parts and openings

Engineering Contradiction:

Improveprotection from environmental damageVSAvoidmoisture, dirt, dust, water damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a flexible waterproof cover made of elastomeric material that conformally seals around the electronic device. This flexible shell approach provides comprehensive protection against moisture, dirt, dust, and water while maintaining a compact and lightweight form factor, avoiding the bulkiness of rigid waterproof housings.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The waterproof cover is divided into multiple functional segments including a main body portion, a separate lens seal assembly with connector mechanism, and fastening components. This segmentation allows the lens area to be specifically sealed while maintaining flexibility and adaptability to different device configurations.

Inventive Principle:

Principle #1Segmentation

2Reliability

If rigid waterproof housings are used to protect electronic devices, then protection from environmental hazards is improved, but the devices become bulky, heavy, and expensive

Engineering Contradiction:

Improvewaterproof protectionVSAvoiddevice weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent replaces rigid waterproof housings with a flexible elastomeric cover that provides equivalent waterproof protection. This flexible shell is significantly lighter and more compact than traditional rigid waterproof cases, eliminating the bulk and weight penalties while maintaining reliable protection against water and environmental hazards.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If custom-fitted waterproof chambers are manufactured for specific device models, then sealing effectiveness is improved, but versatility across different device shapes and configurations is reduced

Engineering Contradiction:

Improvesealing effectivenessVSAvoidcompatibility with multiple devices

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The waterproof cover is designed as a universal solution that can accommodate multiple electronic device models and configurations. The flexible elastomeric material and adjustable connector mechanism allow the same cover design to effectively seal around devices of varying shapes and sizes, eliminating the need for custom-fitted chambers for each device model.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connector mechanism incorporates dynamic adjustment capabilities that allow the seal to adapt to different device geometries. The flexible nature of the elastomeric material enables the cover to conform to various device shapes while maintaining effective sealing, providing both customization and universality.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If simple plastic bags are used for waterproofing, then cost and complexity are reduced, but protection effectiveness and usability are compromised

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidprotection effectiveness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent uses a sophisticated flexible elastomeric cover with integrated sealing mechanisms, lens accommodations, and fastening systems. While more complex than simple plastic bags, this engineered flexible shell provides superior protection effectiveness, proper lens sealing, and maintained usability, representing an optimized balance between manufacturing complexity and protection reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A cover and seal assembly for an electronic device comprises a cover defining a space and having an opening therein with a peripheral edge through which the electronic device can be inserted or removed, and a seal assembly for sealing the opening. The seal has a base portion having a circular side wall with a top edge and bottom edge, an outer peripheral flange, an inner glass support shelf, a lens fastened to and supported on the inner glass support shelf, and a depending wall extending downwardly from the inner glass support shelf. A washer is mounted on the outer peripheral flange for capturing the peripheral edge of the cover. A nut connects to the circular side wall for maintaining the washer in a fixed position on the outer peripheral flange.
