Solution Overview

Problem

The existing transport systems for above-ground construction sites require a large amount of space and numerous guys for anchoring, which increases the effort and complexity of setup and teardown, especially when multiple cranes and elevators are used.

Innovation Solution

A transport system where the revolving tower crane and construction elevator share a common guying system, reducing the number of required guys and minimizing space requirements by using a single elevator tower to support both the crane and the elevators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate guying systems are used for revolving tower crane and construction elevator, then each equipment can be independently anchored, but the number of required guys and construction space increases significantly

Engineering Contradiction:

Improveindependent anchoring capabilityVSAvoidnumber of guys

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines the guying systems of the revolving tower crane and construction elevator into a single common guying structure. The guyed elevator tower and crane tower share common guying points and guying lines, reducing the total number of guys required while maintaining independent anchoring capability for both equipment through the shared structure.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate construction equipments are positioned on the outer skin of the building, then each equipment can operate independently, but the required construction space increases

Engineering Contradiction:

Improveindependent operation capabilityVSAvoidconstruction space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent implements a nested configuration where the crane tower is positioned within the guyed elevator tower structure. This nesting arrangement allows both the construction elevator and revolving tower crane to operate independently while sharing the same spatial footprint, significantly reducing the required construction space at the front of the building.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Quantity of substance

If a common guying system is used for revolving tower crane and construction elevator, then the number of guys and space requirements are reduced, but the structural complexity increases

Engineering Contradiction:

Improvenumber of guysVSAvoidcommon guying structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The common guying structure serves multiple functions simultaneously: it provides anchoring for both the guyed elevator tower and the revolving tower crane, acts as a shared support system, and reduces the total number of guying components required. This multi-functionality approach simplifies the overall system despite the integrated design.

Inventive Principle:

Principle #6Universality (Multi-functionality)
