Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handling heavy loads with lifting and moving equipment poses a risk of collision between the load and its surroundings, potentially damaging the load and surrounding structures, and existing safety measures put operators at risk by requiring them to be close to the load.
Innovation Solution
Attaching proximity sensors around the load's lateral surface to detect obstacles and transmit signals to a display unit, allowing operators to monitor the movement from a safe distance and avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators are placed close to the load to monitor for collision, then collision detection capability is improved, but operator safety deteriorates
Solution Approach 1:
The patent introduces proximity sensors as intermediary devices that detect obstacles near the load without requiring operators to physically approach it. The sensors act as mediators between the operators and the load, providing collision detection capability while maintaining operator safety at a distance.
Solution Approach 2:
The patent replaces the mechanical approach of operators physically monitoring the load with an electronic sensing system. Proximity sensors using electromagnetic fields or other non-contact detection methods substitute for the mechanical presence of operators near the load, eliminating the safety risk while maintaining detection capability.
2Measurement precision
If operators enter the lifting cone to monitor load movement, then collision monitoring is improved, but safety rules are violated and operator risk increases
Solution Approach 1:
Proximity sensors serve as intermediaries that perform the monitoring function normally requiring operator presence. These sensors are attached to the load and detect obstacles in the lifting cone area, eliminating the need for operators to enter this hazardous zone while maintaining effective collision monitoring.
Solution Approach 2:
The patent creates a virtual representation of the physical monitoring situation through sensor data and display units. Instead of operators directly observing the load, they view a copied representation of sensor readings on display units, which suffices for safe monitoring without physical presence in the lifting cone.
3Measurement precision
If multiple operators monitor the load simultaneously, then monitoring coverage is improved, but coordination complexity increases
Solution Approach 1:
The patent merges the monitoring functions of multiple operators into a single integrated sensor system. Multiple proximity sensors work together as one unified detection network, and multiple display units present unified sensor data, eliminating the coordination complexity that would arise from multiple independent operators while maintaining comprehensive monitoring coverage.
Solution Approach 2:
The sensor system performs multiple monitoring functions simultaneously - detecting obstacles from different angles, providing continuous surveillance, and supplying data to multiple display units. This multi-functional system replaces multiple specialized operators, reducing coordination complexity while maintaining or improving monitoring coverage.
