Solution Overview

Problem

Outdoor monitors face challenges in balancing mobility and waterproofing, with existing glue-based sealing methods compromising mobility and reworkability.

Innovation Solution

A rotating base design featuring a first housing, second housing, rotating assembly, and annular elastic members that prevent moisture ingress by compressing between the housings, eliminating the need for glue and allowing easy rework.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If glue is applied to the gaps of joints to achieve waterproofing, then waterproofing performance is improved, but mobility and reworkability deteriorate

Engineering Contradiction:

Improvewaterproofing performanceVSAvoidmobility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent uses an elastic waterproof film that can be stretched and deformed to seal gaps between joints. This flexible film maintains waterproofing while allowing the monitor to move and adjust angles, resolving the contradiction between waterproofing and mobility.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The waterproofing solution transitions from a static glued joint to a dynamic elastic film that can adapt to movement. The film stretches and contracts with the joints, maintaining sealing effectiveness while accommodating mobility requirements.

Inventive Principle:

Principle #15Dynamics

2Reliability

If glue is applied to the gaps of joints to achieve waterproofing, then waterproofing performance is improved, but reworkability deteriorates

Engineering Contradiction:

Improvewaterproofing performanceVSAvoidreworkability

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The elastic waterproof film can be easily removed and reinstalled without damage, unlike glued joints that require destructive removal. This enables straightforward rework and maintenance while maintaining effective waterproofing.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The elastic film acts as a removable sealing element that can be replaced if needed, providing an economical and simple solution for maintenance and rework compared to permanent adhesive bonding.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
