Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional latticed steel section towers are used for windfence support, then wind force resistance is achieved, but manufacturing cost and installation complexity increase significantly

Engineering Contradiction:
Improvewind force resistanceVSAvoidtower structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The tower is divided into distinct functional components: a central compression member, four inclined tension members, and four vertical tension members. This segmentation allows each element to be optimized for its specific function while simplifying the overall assembly process and reducing manufacturing complexity compared to traditional latticed structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using compression members for primary structural support (traditional approach), this invention inverts the approach by using tension members as the primary structural elements. The four vertical tension members anchored to the ground provide the main structural support, while the central compression member serves a secondary role. This inversion simplifies the structure and reduces the number of required elements.

Inventive Principle:
Principle #13The other way round (Inversion)

2Stability of the object's composition

If large concrete bases are used for tower support, then structural stability is improved, but interference with infrastructure and installation difficulty increase

Engineering Contradiction:
Improvetower stabilityVSAvoidinstallation ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention extracts the stability function from the large concrete base and redistributes it through four smaller independent foundations positioned around the central tube. This extraction eliminates the need for a single large base, reducing interference with infrastructure while maintaining stability through the distributed foundation system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a single large base in one location, the stability function is distributed across four foundations in different spatial positions around the central tube. This dimensional distribution maintains stability while minimizing interference with infrastructure elements that may be located between the foundations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If traditional tower designs are used, then windbreak function is provided, but installation time and patio interdiction period increase

Engineering Contradiction:
Improvewindbreak effectivenessVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The tower design incorporates adjustable tensioners on the vertical tension members, allowing for dynamic adjustment of tension forces during installation. This enables the structure to be quickly assembled and tuned to the required wind load conditions, reducing installation time while maintaining windbreak effectiveness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The four vertical tension members are pre-tensioned during assembly before the windfence is fully installed. This preliminary action ensures that the structural stability is established early, allowing for quicker completion of the overall installation and reducing the patio interdiction period.

Inventive Principle:
Principle #10Preliminary action

4Strength

If latticed steel sections are used for towers, then structural strength is achieved, but material quantity and cost increase

Engineering Contradiction:
Improvestructural strengthVSAvoidmaterial quantity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The tower uses a composite system combining compression and tension members with different structural roles. The central compression member and four inclined tension members work together with the four vertical tension members to create a efficient load-distributing system that requires less total material than traditional latticed structures while maintaining equivalent or superior strength.

Inventive Principle:
Principle #40Composite materials

AI summary

A windfence supporting tower with tension-integrity, includes a tubular metal tower having a central tubular post and four inclined tubular structural tensile elements attached to the post via the coupling ring and the lower ends attached to the free ends of a yoke of compression tubes, which is in turn attached to the post by the reaction flange of the yoke, further receiving at the free ends of the yoke four vertical tensile structural elements which are tensioned and anchored to the ground through four independent foundations located around the foundation of the central tube. These vertical ties pull on the connection point of the yoke and in turn the inclined structural elements connected to the coupling ring, thereby providing stability with tension-integrity, which is the main feature of the present supporting tower for absorbing forces caused by the wind.
