Reclining chaise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture often compromises on motion functionality for aesthetic design, limiting the incorporation of both aesthetics and functionality in motion furniture like chaise lounges.
Innovation Solution
A furniture design that includes a base frame, a chaise seat bottom frame, and a seatback frame, where the seatback frame and chaise seat bottom frame are movable between upright and reclined positions, with a linkage system allowing simultaneous movement of both frames, and optional motor-driven or manual actuation for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional furniture design prioritizes aesthetic design, then appearance is improved, but motion functionality is limited
Solution Approach 1:
The furniture member incorporates dynamic motion mechanisms including a seatback frame movable between upright and reclined positions, and a chaise seat bottom frame movable between first and second positions, allowing the furniture to adapt its configuration while maintaining aesthetic design. The linkage system enables smooth transitions between positions without compromising appearance.
2Adaptability or versatility
If motion functionality is incorporated into furniture, then adaptability is improved, but device complexity increases
Solution Approach 1:
The linkage system merges the movement of the seatback frame and chaise seat bottom frame into a coordinated mechanism. The first link connects the seatback frame to the base frame, while the second link connects the chaise seat bottom frame to the seatback frame, creating an integrated system where both frames move simultaneously and cooperatively, reducing overall structural complexity.
Solution Approach 2:
The linkage system serves multiple functions: it enables the seatback frame to recline, allows the chaise seat bottom frame to move between positions, and coordinates these movements simultaneously. This multi-functionality reduces the need for separate mechanisms for each motion, thereby reducing device complexity.
3Ease of operation
If simultaneous movement of seatback frame and chaise seat bottom frame is achieved, then user comfort is improved, but mechanism complexity increases
Solution Approach 1:
The linkage system combines the reclining motion of the seatback frame with the movement of the chaise seat bottom frame into a single coordinated mechanism. When the seatback frame moves from upright to reclined position, the chaise seat bottom frame simultaneously moves from the first position to the second position, providing synchronized motion that enhances user comfort without requiring multiple independent mechanisms.

AI summary
A furniture member may include a base frame, a chaise seat bottom frame, and a seatback frame. The chaise seat bottom frame is supported by the base frame and is movable relative to the base frame between first and second positions. The chaise seat bottom frame includes an upper-leg-supporting portion and a lower-leg-supporting portion that are fixed to each other. The lower-leg-supporting portion may support an occupant's lower legs in an extended position relative to the occupant's upper legs. The seatback frame may be supported by the base frame and may be movable relative to the base frame and the chaise seat bottom frame between upright and reclined positions. Movement of the seatback frame from the upright position to the reclined position causes movement of the chaise seat bottom frame upward and forward relative to an aft end of the base frame from the first position to the second position.
