Solution Overview

Problem

Traditional tower cranes have limited hoisting capacity, especially for long distances, and are immovable, leading to low utilization rates and inefficiencies in construction, particularly with the rise of prefabricated building components and the need for horizontal transportation and installation, while their bases cause construction waste and resource inefficiencies.

Innovation Solution

A multi-tower linkage type aerial hoisting platform with a self-climbing lifting/lowering system and hydraulic locking mechanism, forming a stable rectangular platform using tower crane body support beams that can move vertically and horizontally, incorporating movable bases for recyclability and expandable anchor points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If traditional tower cranes are used for long-distance hoisting, then the hoisting capacity is limited due to arm balancing, but the structure remains stable

Engineering Contradiction:
Improvehoisting capacityVSAvoidlifting distance
Core Design Contradiction:
ForceVSLength of moving object

Solution Approach 1:

The tower crane body is divided into multiple standard sections that can be independently assembled and configured. This segmentation allows the boom length and hoisting capacity to be adjusted separately, enabling long-distance hoisting without compromising the overall structural stability through proper section configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tower crane incorporates a movable counterweight system that can be dynamically adjusted along the boom. This dynamic adjustment allows the crane to maintain arm balancing stability while accommodating varying lifting distances and loads, effectively increasing hoisting capacity for long-distance operations.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If tower crane bases are integrally poured by reinforced concrete, then the tower crane body is stable, but the bases cannot be relocated causing construction waste and resource inefficiency

Engineering Contradiction:
Improvetower crane body stabilityVSAvoidbase relocatability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The base structure is segmented into a permanent foundation portion and a removable tower crane base portion. The removable base can be detached and relocated to different positions, allowing the tower crane to be moved between construction sites or repositioned within a large construction area while maintaining stability through the permanent foundation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tower crane base is designed to be discarded from its original position and recovered for reuse at another location. This allows the base structure to be removed after the tower crane is dismantled, enabling land reuse and eliminating construction waste from concrete bases.

Inventive Principle:
Principle #34Discarding and recovering

3Area of stationary object

If multiple tower cranes are disposed for large-area construction projects, then the construction region coverage is improved, but the utilization rate decreases due to idle cranes

Engineering Contradiction:
Improveconstruction region coverageVSAvoidcrane utilization rate
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The tower crane system incorporates movable bases and adjustable boom configurations that allow a single crane to dynamically adapt to different construction areas. The crane can be repositioned and reconfigured to cover different zones, replacing the need for multiple fixed cranes and improving utilization rate while maintaining coverage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tower crane body is designed with multi-functionality, serving not only as a lifting device but also as a support platform for elevators, construction platforms, and other construction equipment. This universal application increases the crane's utilization rate across different construction activities and areas.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If conventional tower cranes are used, then the lifting function is provided, but horizontal transportation and installation efficiency is low

Engineering Contradiction:
Improvehorizontal transportation efficiencyVSAvoidinstallation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The tower crane body is designed to serve multiple functions beyond lifting. It provides a horizontal transportation platform through its boom structure and serves as a support platform for construction activities. This multi-functionality integrates lifting, horizontal transportation, and installation operations, significantly improving overall construction efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)
