Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional guy cable brackets are designed for specific installation ships, then the structural reliability is ensured, but the adaptability to different boom structures is reduced and construction costs increase
Solution Approach 1:
The guy cable bracket is divided into multiple adjustable truss rods (first truss rod, second truss rod, third truss rod) that can be independently adjusted in length and angle. This segmentation allows each component to be optimized for different boom configurations while maintaining overall structural integrity and reliability.
Solution Approach 2:
The truss rods are designed with adjustable lengths and angles, transforming the static conventional bracket into a dynamic structure that can adapt to different boom structures. The adjustable connecting ports and hinged connections enable the bracket to change its configuration based on specific installation requirements.
2Reliability
If conventional guy cable brackets are designed for specific installation ships, then the structural reliability is ensured, but the construction costs and resource waste increase
Solution Approach 1:
The guy cable bracket is designed as a universal structure that can be applied to different installation ships and boom configurations. The adjustable truss rods and connecting ports enable a single bracket design to serve multiple functions across different vessels, eliminating the need for ship-specific custom designs and reducing construction costs.
Solution Approach 2:
The bracket allows adjustment of key parameters such as truss rod lengths, connection angles, and port positions. By changing these parameters, the same bracket structure can be adapted to different boom configurations, maintaining operational safety while avoiding the costs of manufacturing multiple specialized brackets.
3Adaptability or versatility
If adjustable truss rods are used in the guy cable bracket, then the adaptability to different boom structures is improved, but the device complexity increases
Solution Approach 1:
The complexity is managed by segmenting the adjustment mechanism into discrete, standardized components such as adjustable truss rods with pin connections and modular connecting ports. Each segment performs a specific function, making the overall complex system manageable and maintainable.
Solution Approach 2:
The adjustable features introduce controlled dynamics to the structure, allowing it to transform between different stable configurations. The hinged connections and adjustable ports provide necessary degrees of freedom while maintaining structural stability during operation, balancing versatility with manageable complexity.
4Adaptability or versatility
If the truss rods are made adjustable in length, then the adaptability to different installation requirements is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The continuous length adjustment is segmented into discrete incremental steps using standardized connection points and pin holes. This segmentation reduces manufacturing precision requirements compared to continuous adjustment, as each segment can be manufactured to standard tolerances and combined to achieve the desired overall length.
Solution Approach 2:
The adjustment mechanism uses standardized parameter changes (discrete length increments, standard angle increments) rather than continuous variation. This approach allows for easier manufacturing with standard tolerances while still providing sufficient adaptability for different installation requirements.

AI summary
A cable support is used for being mounted on a boom, and comprises two trusses symmetrically arranged with respect to the boom. In a first projection plane perpendicular to the length direction of the boom, truss rods of the trusses are arranged in a triangular shape. One end of a second truss rod and one end of a third truss rod are hingedly connected to two ends of a first truss rod, respectively. The other end of the second truss rod is hingedly connected to the other end of the third truss rod. The lengths of the first truss rod, the second truss rod and the third truss rod are all adjustable. The two ends of the first truss rod are respectively provided with detachable connection portions adapted to the boom, and the second truss rod or the third truss rod is provided with a cable rope guide portion.
