Solution Overview

Problem

Conventional seismic support structures for power transmission equipment fail to adequately withstand seismic stress and vibrations, leading to amplified dynamic responses that can damage equipment, especially in seismically active regions.

Innovation Solution

A seismic support structure comprising a pivot structure with angled vertical columns, horizontal struts, and diagonal braces, designed to provide flexibility and increased structural resistance, allowing for effective absorption of seismic movements and reduced equipment acceleration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a relatively rigid conventional support structure is used, then the structure provides sufficient structural resistance, but the dynamic response of equipment is amplified due to limited movement absorption

Engineering Contradiction:
Improvestructural resistanceVSAvoidequipment safety during seismic event
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The support structure transitions from a rigid static design to a dynamic system with controlled movement capabilities. The pivot structure allows rotational movement at the base, while the jaw structure provides controlled displacement, enabling the system to adapt its rigidity during seismic events and reduce equipment acceleration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The structure changes its mechanical parameters during operation. The pivot angle and jaw separation distance are variable parameters that allow the structure to modify its stiffness and energy absorption characteristics in response to seismic loading, optimizing both structural resistance and equipment protection.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a relatively flexible support structure is used, then the structure allows equipment movement during seismic events, but the seismic movement is amplified several times higher

Engineering Contradiction:
Improveequipment movement toleranceVSAvoidseismic movement amplification
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The pivot structure and jaw structure act as intermediary elements between the ground and the equipment. These components filter and control the transmission of seismic movements, preventing direct amplification while allowing necessary equipment movement through controlled degrees of freedom.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a conventional support structure anchored directly to the ground is used, then the structure provides stable support, but the equipment is subjected to amplified seismic movements

Engineering Contradiction:
Improvesupport stabilityVSAvoidequipment acceleration limits
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The support structure is divided into distinct functional segments: the pivot structure for base movement, the vertical columns for support, and the jaw structure for equipment mounting with controlled displacement. This segmentation allows each component to perform its specific function in mitigating seismic effects while maintaining overall stability.

Inventive Principle:
Principle #1Segmentation
