Solution Overview

Problem

Existing underwater protective systems face mechanical weakness due to external welds, which can fail under water pressure and marine impacts, necessitating a device to securely fasten protective covers without relying on wax coatings that can be easily removed.

Innovation Solution

A clamping tool with a clamp, jaw attachment, and locking bolts, where the clamp comprises a first and second claw connected via a pivot, transforming rotational torque into clamping pressure, and the jaw attachment features tubes with aligned holes for locking bolts, allowing secure attachment of protective covers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If plastic covers are joined by external welding, then the covers can be assembled, but the external weld creates mechanical weakness that can fail under water pressure and marine impacts

Engineering Contradiction:
Improveease of assemblyVSAvoidmechanical strength of joint
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent replaces the mechanical welding system with a clamping system that uses mechanical pressure and friction to secure the protective cover. The clamp applies radial force through jaws to hold the cover in place, eliminating the weak external weld while maintaining assembly capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If wax coatings are used to protect marine supports, then the supports are protected from corrosion, but the wax coating can be easily removed by impacts in aggressive marine environments

Engineering Contradiction:
Improveprotection reliabilityVSAvoidresistance to impact
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent applies a rigid protective cover beforehand that cushions and absorbs impacts before they reach the wax coating on the marine support. This pre-protective layer prevents direct impact damage to the vulnerable wax coating, maintaining both corrosion protection and impact resistance.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If a clamping tool is used to secure protective covers, then the covers remain secure under water pressure, but the installation process requires additional equipment

Engineering Contradiction:
Improvesecuring reliabilityVSAvoidinstallation equipment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamp is designed to be self-adjusting and self-securing. Once positioned around the protective cover, the clamp automatically applies and maintains the necessary clamping force through its mechanical advantage system, requiring minimal operator intervention and no additional complex equipment during installation.

Inventive Principle:
Principle #25Self-service

4Strength

If heavy duty equipment and extensive workforce are used for infrastructure construction, then large structures can be built over water, but the construction process becomes more complex and resource-intensive

Engineering Contradiction:
Improvestructural strengthVSAvoidconstruction system complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent segments the protective cover system into modular components that can be independently installed and secured. The clamp serves as a standardized, reusable component that simplifies the assembly process for each segment, reducing the need for heavy equipment and extensive workforce while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation
