Solution Overview

Problem

Existing self-climbing devices for concrete surfaces require tracks, guides, or rails, limiting their applicability to flat surfaces and increasing assembly and dismantling costs, and are not suitable for quasi-vertical or complex geometries like prefabricated concrete towers.

Innovation Solution

A self-climbing device with motorized frames that can independently move along a main beam, featuring anchoring and locking mechanisms, and linear actuators for horizontal and vertical displacement, allowing adaptation to irregular surfaces and rotation, enabling climbing on vertical and quasi-vertical surfaces without external rails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tracks, guides or rails are solidly joined to the working surface, then the device can climb stably, but the assembly and dismantling become more expensive and complex

Engineering Contradiction:
Improveclimbing stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the tracks, guides, or rails from the system by having the device anchor directly to the concrete surface through anchoring cones that insert into hollows formed in the concrete. This extraction eliminates the need for separate guiding infrastructure while maintaining climbing stability through direct surface engagement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The anchoring cones serve as intermediaries between the device and the concrete surface. These cones insert into hollows formed in the concrete and provide both anchoring and guiding functions, replacing the need for separate tracks or rails while maintaining stable climbing operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If tracks, guides or rails are used, then the device can maintain position accurately, but the application is limited to flat surfaces only

Engineering Contradiction:
Improveposition accuracyVSAvoidsurface geometry adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device is designed with universal anchoring cones that can engage with concrete surfaces of various geometries including vertical, quasi-vertical, and curved surfaces. The anchoring cones maintain position accuracy through their interaction with hollows formed in the concrete surface, regardless of the surface's geometric complexity, enabling application on prefabricated concrete towers and other non-flat structures.

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

3Reliability

If external rails are used for raising parts, then the device can operate reliably, but the device cannot climb inside hollow concrete towers

Engineering Contradiction:
Improveoperational reliabilityVSAvoidstructure type applicability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent removes the external rails infrastructure and replaces it with anchoring cones that directly engage the concrete surface. This allows the device to climb inside hollow concrete towers by anchoring to the inner surface, eliminating the need for external rail systems and expanding applicability to various structural configurations including hollow towers.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of manufacture

If anchoring cones are used for fixing to the wall, then the device can attach to the surface, but the device does not autonomously climb and requires manual dismantling

Engineering Contradiction:
Improveattachment capabilityVSAvoidautonomous climbing capability
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The device is equipped with self-motorized frames that autonomously move along the main beam using drive mechanisms. The anchoring cones are positioned and engaged automatically as the device climbs, eliminating the need for manual attachment or dismantling operations. The system serves itself by integrating automated positioning and anchoring functions.

Inventive Principle:
Principle #25Self-service
