Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional slacklines are statically fixed to anchor points, then the structure is simple and stable, but the height and tension cannot be adjusted dynamically
Solution Approach 1:
The patent applies dynamics by replacing static fixed anchor points with motorized tensioning assemblies that can dynamically adjust the height and tension of the slackline. The tensioning motors and linear actuators enable the system to transition from a fixed state to an adjustable state, allowing performers to change height and tension during performances.
Solution Approach 2:
The patent substitutes manual mechanical adjustment systems with automated motorized systems. Tensioning motors replace manual ratchets and winches, while linear actuators replace manual height adjustment mechanisms. This substitution enables automated control of slackline parameters through control circuitry.
2Productivity
If conventional slacklines use manual adjustment of ratchets and webbing, then the system is simple, but tension adjustment is time-consuming and cannot be done during performance
Solution Approach 1:
The patent replaces manual mechanical tensioning systems with motorized tensioning mechanisms. Tensioning motors with spools automatically wind or unwind the slackline webbing to adjust tension, eliminating the need for manual ratchet adjustment. This enables rapid tension changes during performances.
Solution Approach 2:
The control circuitry automatically controls the tensioning motors to maintain nominal tension on the slackline during height adjustments. The system self-regulates tension without requiring manual intervention, performing the tensioning function automatically based on sensor feedback and control algorithms.
3Adaptability or versatility
If slackline height is changed by manual repositioning, then the system remains simple, but the suspended portion cannot be raised and lowered while maintaining tension
Solution Approach 1:
The patent applies dynamics by implementing motorized linear actuators that enable dynamic height adjustment of the tensioning assemblies. These actuators move the tensioning assemblies vertically along guide rails, allowing the slackline height to be changed during performances while maintaining tension through coordinated motor control.
Solution Approach 2:
The control circuitry uses feedback from sensors to monitor the position and tension of the slackline, automatically adjusting the linear actuators and tensioning motors to maintain nominal tension during height changes. This closed-loop control enables dynamic height adjustment without compromising tension stability.
4Adaptability or versatility
If conventional slacklines are fixed in position, then installation is simple, but they cannot be repositioned or have dynamic visual effects
Solution Approach 1:
The patent implements dynamic repositioning capability through motorized tensioning assemblies that can move along guide rails and adjust their position horizontally and vertically. This enables the slackline to be repositioned to different locations and heights, creating dynamic visual effects and adapting to different performance requirements.
Data Source
AI summary
Deployable slackline systems are disclosed which can support a slackline at a desired height and nominal tension. The disclosed systems may maintain one or more slacklines and can adjust height and tension of individual slacklines while the slacklines are in use. The disclosed slackline systems are stowable; tensioning and termination assemblies of the slackline system can each fold into a compact housing having a height substantially less than a vertical range of motion of the slackline. The disclosed slackline systems can be implemented in aquatic or non-aquatic performance environments such as on cruise ships or other hospitality settings.
