Suspended Theater Seating Motion Base for Unobstructed Sightlines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional theater seating systems fail to provide unobstructed views for all patrons due to fixed seating arrangements on flat floors, leading to obscured lines of sight, especially for viewers behind taller individuals, and existing solutions with complex mechanical designs can cause adverse reactions and limited vertical motion experiences.
Innovation Solution
An inverted motion base system with vertically oriented seating, utilizing left and right load carrying arms and cables to elevate rows of seats, allowing for parallel orientation and varying heights, enabling better visibility and enhanced vertical separation between rows, along with roll and heave motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rows of seats are fixed to a flat floor, then the structure is simple and stable, but viewers behind taller individuals have obscured views of the screen
Solution Approach 1:
The patent transitions from a two-dimensional flat floor seating arrangement to a three-dimensional suspended seating system. Rows of seats are hung from overhead supports at varying heights, creating vertical separation that eliminates line-of-sight obstructions while maintaining structural simplicity through the use of basic suspension mechanisms.
2Adaptability or versatility
If complex mechanical structures are used to provide motion sensation, then physical motion experience is enhanced, but patrons experience adverse reactions and fear of crashing
Solution Approach 1:
The patent employs dynamic motion base technology that allows the suspended seating rows to move in multiple dimensions (pitch, roll, yaw, heave) in synchronization with the on-screen action. This controlled dynamic movement provides realistic motion sensation without the chaotic, uncontrolled movements that cause patron fear, creating an immersive experience that feels safe yet authentic.
3Ease of operation
If all rows of seats are positioned on the same level, then the loading process is simple, but the viewing experience is compromised due to obscured lines of sight
Solution Approach 1:
The patent segments the seating system into independently controllable rows that can be positioned at different vertical levels. Each row is suspended separately on its own motion base, allowing individual adjustment of height and orientation. This segmentation enables optimized viewing angles for all patrons while maintaining simple loading procedures through automated positioning systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides unobstructed views for all patrons by adjusting seat heights and orientations, reducing the risk of adverse reactions and enhancing the immersive experience through controlled vertical and lateral movements.
Implementation Method 1
a first cable connected at a first end to the carriage, the first cable having a second end wound about a first rotatable drum, wherein the first cable in combination with the first rotatable drum raises and lowers the carriage
Implementation Method 2
a second cable connected at a first end to a second end of the right load carrying arm, the second cable having a second end wound about a second rotatable drum, wherein the second cable in combination with the second rotatable drum raises and lowers the second end of the right load carrying arm
Implementation Method 3
a transverse support member pivotably coupled to the knuckle; left and right load carrying arms, each connected at a first end to a respective left and right ends of the transverse support member

AI summary
An improved inverted motion base with left, right, and rear supports, a carriage to travel along a length of the rear support. The inverted motion base includes a first cable connected to the carriage and wound about a first drum to raise and lower the carriage, and left and right load carrying arms, each connected to a respective left and right ends of a transverse support member. The inverted motion base further includes a second cable connected to the right load carrying arm to raise and lower the right load carrying arm, and a third cable connected to the left load carrying arm to raise and lower the second end of the left load carrying arm. One or more rows of seats are positioned between and suspended from the right and left load carrying arms, each row of seats being parallel to the other row of seats.
