Solution Overview

Problem

Existing crane deployment planners require significant administrative effort for maintenance, are complex to use, and do not adequately support users in planning and implementing crane operations, especially with new crane components, due to the need for manual data entry and interpolation of crane configurations and positions.

Innovation Solution

A crane scheduler with a central planning unit that includes a database for crane and component data and a calculation module using a physical model to determine load moments, accessible via the Internet, reducing the need for local software maintenance and enabling real-time calculations and realistic simulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If crane deployment planners are installed locally at customer sites with pre-calculated tabular data for all crane configurations and positions, then simulation and calculation can be performed, but maintenance effort and administrative burden become very high

Engineering Contradiction:
Improvesimulation capabilityVSAvoidmaintenance effort
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the calculation module and central database into a single centralized planning unit that serves multiple customers. This consolidation eliminates the need for each customer to maintain separate local installations with pre-calculated tabular data, reducing overall maintenance effort while preserving simulation capabilities through centralized web-based access.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a web server as an intermediary between the central planning unit and customers. This web-based interface allows customers to access crane deployment planning functionality without requiring local software installations, thereby eliminating the maintenance burden of local tabular data while maintaining full simulation capabilities through the centralized system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If tabular data is pre-calculated and stored for all possible crane configurations and positions, then load moments can be determined during simulation, but the system becomes complicated to use and requires significant data management effort

Engineering Contradiction:
Improveplanning efficiencyVSAvoiduser friendliness
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical approach of pre-calculating and storing tabular data for all crane configurations with a computational approach using a physical model. The calculation module continuously calculates load moments based on actual crane parameters and operating conditions, eliminating the need for users to navigate complex pre-calculated data tables and making the system more intuitive and easier to use.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transitions from static pre-calculated tabular data to dynamic real-time calculations based on the physical model. The system adapts to any crane configuration and position on-demand, allowing users to simply input their specific operating parameters and receive immediate results without needing to search through or interpolate from pre-calculated data sets.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If new crane components are introduced, then crane capabilities are enhanced, but all local crane deployment planners must be updated and maintained

Engineering Contradiction:
Improvecrane configuration optionsVSAvoidsoftware update burden
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The patent creates a universal centralized planning unit that serves multiple customers and accommodates all crane configurations through a single system. When new crane components are introduced, only the central database and calculation module need to be updated, and all customers automatically benefit from the enhanced capabilities through the web interface, eliminating the need to update multiple local installations.

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

Solution Approach 2:

The patent performs preliminary centralization of the planning system, anticipating future crane component additions. By establishing a centralized architecture from the beginning, the system is pre-positioned to easily accommodate new crane components through centralized database updates, avoiding the recurring burden of distributing and maintaining updates across numerous local installations.

Inventive Principle:
Principle #10Preliminary action
