Solution Overview

Problem

Existing support structures for items like heliostats and wind turbines are costly and face challenges on undulating ground, requiring significant welding and additional corrosion protection, which complicates stability and accuracy in tracking energy sources.

Innovation Solution

A height adjustable pylon and frame assembly with tubular frame members and a fastener assembly that allows for axial locking of pylons at selected positions, using deformable metal or suitable materials with pre-formed contact surfaces and adjustable brace members to accommodate uneven terrain without welding, enabling easy assembly and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional welded support structures are used, then structural strength and stability are improved, but manufacturing cost and complexity increase due to significant welding and corrosion protection requirements

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The support structure is divided into modular components: adjustable pylons, frame members with pre-formed contact surfaces, and fastener assemblies. These segments can be manufactured separately and assembled without welding, reducing manufacturing cost and complexity while maintaining structural integrity through mechanical connections

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the connection method parameter from welded joints to mechanical fastening systems. The fastener assemblies with saddle portions engage the pylon surfaces and lock them axially, providing sufficient structural strength without the need for welding and associated corrosion protection

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If welded frame structures are used, then structural stability is improved, but adaptability to undulating ground deteriorates

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

Solution Approach 1:

The support structure incorporates adjustable pylons that can be positioned at different heights and locked in place using fastener assemblies. This dynamic adjustability allows the structure to adapt to undulating ground conditions while maintaining stability, unlike fixed welded structures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The frame members include pre-formed contact surfaces that conform to the outer surface of the pylon before assembly. This preliminary preparation ensures proper engagement and stability when the pylon is locked in position, accommodating terrain variations without requiring post-installation adjustments

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If adjustable pylon positions are implemented, then tracking accuracy of energy sources is improved, but device complexity increases

Engineering Contradiction:
Improvetracking accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The fastener assembly acts as an intermediary mechanism between the adjustable pylon and the frame members. It provides a simple mechanical means for positioning and locking the pylon at selected heights, achieving tracking accuracy without complex adjustment mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The pre-formed contact surfaces on the frame members are designed to conform to the pylon outer surface, enabling self-alignment and stable engagement when the fastener assembly is tightened. This self-adjusting feature reduces the complexity of precision manufacturing while maintaining positioning accuracy

Inventive Principle:
Principle #25Self-service

AI summary

A height adjustable pylon (2, 15) and supporting frame assembly (1) is provided. The frame includes two frame members (3) meeting at a corner with the frame members being generally co-planar and the pylon (2, 15) being urged into the corner so as to extend at generally right angles to a plane including the two frame members. A fastener assembly has two end portions (23) each anchored relative its associated frame member so as to extend transversely to it. The fastener assembly (21) includes an intermediate saddle portion (22) engaging a surface of the pylon (2) that is directed outwardly relative to the corner with the pylon being urged into the corner when the fastener assembly is tightened to engage the pylon and lock it axially relative to the frame members (3) in a selected position. Preferably, the frame members each form two upper and two lower frame members of two trusses. Lower ends of the pylons may support the assembly.
