Innovation Solution

A modular casing tensioner platform frame kit with prefabricated components, including frame components, corner connectors, and rod connections, allowing for assembly and disassembly without welding, enabling field assembly and reducing transportation and installation costs while ensuring quality and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If components are combined in a non-removable manner (welding) to form a monolithic casing tensioner platform frame, then structural strength and stability are improved, but transportation cost and installation complexity increase significantly

Engineering Contradiction:
Improvestructural strengthVSAvoidtransportation and installation cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The casing tensioner platform frame is divided into multiple removable components including corner connectors, front beams, lateral beams, posts, and rod assemblies. These segmented components can be transported separately and assembled on-site using connection brackets and fastening mechanisms, eliminating the need for welding while reducing transportation and installation costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables components to be disassembled and reused. The corner connectors with connection brackets allow rods and beams to be removed and reassembled, facilitating component recovery and reuse, which reduces long-term costs and improves ease of manufacture.

Inventive Principle:
Principle #34Discarding and recovering

2Ease of manufacture

If components are transported separately and welded at field, then transportation cost is reduced, but welding quality and safety are significantly affected due to harsh offshore environment

Engineering Contradiction:
Improvetransportation costVSAvoidwelding quality
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The welding process is replaced with a mechanical connection system. Corner connectors equipped with connection brackets use fastening mechanisms (bolts, pins, or interlocking features) to join rods and beams mechanically, eliminating the need for welding in harsh offshore environments while maintaining connection reliability.

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

Solution Approach 2:

Connection brackets serve as intermediary components between rods and beams. These brackets provide a standardized interface that facilitates easy mechanical attachment and detachment, replacing direct welding joints and enabling reliable assembly without exposure to environmental hazards.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a fixed structure with non-removable components is used, then structural stability is improved, but adaptability and ease of maintenance are reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The structure transitions from a fixed monolithic design to a dynamic modular system. Components can be assembled, disassembled, and reconfigured using corner connectors and connection brackets, allowing the structure to adapt to different operational requirements while maintaining stability through proper mechanical joining.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Corner connectors and connection brackets serve as universal interface components that can join multiple types of structural elements (rods, beams, posts). This multi-functional connection system provides both structural stability and adaptability, allowing the same components to be used in various configurations.

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