Modular assembly for high leg row seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial environments such as movie theaters face challenges in accommodating motion furniture that can move between closed, extended, and fully reclined positions due to uneven flooring and space constraints, requiring a design that addresses these issues while maintaining comfort and minimizing row spacing.
Innovation Solution
A modular base system with adjustable legs for leveling, easy removal and replacement of components, a low-profile metal footrest plate, and a slim profile chair back assembly that allows seat pitch change and easy access for repair, along with a mechanism to pivot the seat upward for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion furniture is used in commercial environments, then comfort is improved, but space requirements increase and installation becomes difficult due to uneven flooring
Solution Approach 1:
The patent implements a dynamic seat pitch mechanism that automatically adjusts the seating angle during recline motion. The seat pitch changes from the closed position to the extended position, and from extended to fully reclined position, optimizing comfort while minimizing space requirements between rows
Solution Approach 2:
The patent employs adjustable leg mechanisms that modify the structural parameters of the base system to accommodate uneven flooring surfaces. This allows the motion furniture to adapt to varying floor conditions without requiring additional space or complex installation procedures

3Ease of operation
If complex mechanisms are added for seat pitch change, then comfort is improved, but device complexity increases
Solution Approach 1:
The patent combines the seat pitch adjustment function with the existing recline mechanism. The mechanism that drives the recline motion also drives the seat pitch change, eliminating the need for separate control systems and reducing overall device complexity while maintaining comfort benefits
