Solution Overview

Problem

Existing buoyancy adjustment systems for underwater housings, such as those containing cameras, are cumbersome and difficult to handle due to their inherent buoyancy, which restricts user movement and convenience when capturing images in water.

Innovation Solution

A buoyancy adjusting apparatus with a volume-changeable portion and an operation receiver that allows users to adjust the buoyancy of the housing by changing the volume of the volume-changeable portion, enabling neutral buoyancy and facilitating easier handling and image capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing buoyancy adjustment systems are used for underwater housings, then the housing can maintain buoyancy, but the system becomes cumbersome and difficult to handle

Engineering Contradiction:
Improvebuoyancy maintenanceVSAvoidhandling convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies parameter changes by modifying the volume of the buoyancy adjustment chamber through a piston mechanism. The piston can be moved to change the internal volume of the chamber, thereby adjusting the buoyancy force according to Archimedes' principle. This allows continuous adjustment of buoyancy parameters without requiring complex mechanical systems or multiple separate components, resolving the contradiction between reliable buoyancy maintenance and ease of operation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If buoyancy adjustment mechanisms are added to underwater housings, then buoyancy control is achieved, but the device complexity increases

Engineering Contradiction:
Improvebuoyancy controlVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The piston mechanism serves multiple functions: it acts as both the buoyancy adjustment mechanism and a sealed movable boundary for the pressure-sensitive chamber. The same component that changes volume also maintains pressure differential and controls fluid communication. This multi-functionality reduces the number of separate parts needed, thereby reducing device complexity while maintaining adaptability for buoyancy control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If volume-changeable portion is used to adjust buoyancy, then buoyancy adjustment is achieved, but the housing structure becomes more complex

Engineering Contradiction:
Improvebuoyancy adjustmentVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The piston is nested within the buoyancy adjustment chamber, and the chamber itself is integrated into the housing structure. The piston chamber is contained within the larger housing, creating a nested configuration. This nesting approach allows the volume-changeable portion to be incorporated without significantly increasing external dimensions or structural complexity, while still enabling easy buoyancy adjustment through piston movement.

Inventive Principle:
Principle #7Nested doll (Nesting)
