Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for movable platforms are limited in their ability to operate on complex trajectories, require rigid attachments, and lack flexibility in movement and setup, making them less versatile and aesthetically appealing for applications such as entertainment and display purposes.
Innovation Solution
A flexibly supported movable platform system using onboard and offboard actuators and sensors that allows movement along complex 6D trajectories, enabling dynamic movements and orientations without the need for rigid attachments, weighting, or bracing, and allowing integration with other effects like video and lighting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid attachments and bracing are used to support the platform, then structural stability is improved, but flexibility of movement and ease of setup are worsened
Solution Approach 1:
The patent replaces rigid mechanical support structures with a flexible cable suspension system combined with active actuators. The flexible cables provide support while allowing complex 6D movement, and actuators (motors, winches, or robotic arms) actively stabilize the platform, substituting passive mechanical bracing with active control mechanisms.
Solution Approach 2:
The system transitions from static rigid support to dynamic flexible support. The flexible cables allow the platform to move freely in six degrees of freedom, while actuators dynamically adjust cable tensions and positions to maintain stability during movement, enabling both flexibility and stability simultaneously.
2Adaptability or versatility
If complex 6D trajectory movement is enabled, then versatility and aesthetic benefits are improved, but device complexity is worsened
Solution Approach 1:
The complex 6D movement system is segmented into independent control components: separate actuators for each flexible support cable, individual motor controls for positioning, and modular sensor systems. This segmentation allows complex functionality to be achieved through coordinated simple components, managing overall system complexity.
Solution Approach 2:
The flexible cable suspension system with actuators serves multiple functions simultaneously: it supports the platform's weight, enables complex 6D movement trajectories, provides positioning control, and allows easy reconfiguration. This multi-functionality reduces the need for separate specialized components for each function.
3Productivity
If multiple platforms are used simultaneously, then productivity and versatility are improved, but coordination and control complexity are worsened
Solution Approach 1:
Each platform uses identical flexible cable suspension and actuator systems, creating universal modular units. This standardization allows multiple platforms to be controlled simultaneously through a unified control architecture, managing coordination complexity through consistency across units.
