Folding Recliner Locking Mechanism for Stable Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recliners are bulky and unstable, making them difficult to move, lack flexibility in reclining positions, and cannot be easily folded for storage or transport, and require complex structures to support user weight and provide stable reclining movements.
Innovation Solution
A recliner with a folding frame and a locking mechanism at the bottom of the armrests, allowing users to adjust and lock the inclination angle using leg and body forces, enabling safe folding and compact storage without expensive or complicated structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional recliner uses a bulky supporting frame to support user weight and provide stable reclining movement, then stability and strength are improved, but mobility and ease of storage deteriorate
Solution Approach 1:
The recliner frame is divided into separable components including a folding front leg assembly, a rear leg assembly, and an armrest assembly with integrated locking mechanism. This segmentation allows the recliner to be disassembled for easy storage and transport while maintaining structural integrity during use
Solution Approach 2:
The recliner incorporates a dynamic locking mechanism that transitions between locked and unlocked states. The locking mechanism includes a locking member that engages with a locking surface on the armrest, allowing the recliner to maintain a fixed stable position during use while enabling easy reconfiguration and folding for mobility
2Adaptability or versatility
If a foldable frame is used to enable the recliner to be folded for storage and transport, then ease of storage is improved, but structural rigidity and stability deteriorate
Solution Approach 1:
The locking mechanism is designed to be engaged before the recliner is fully assembled or before use. The locking member is positioned on the armrest such that when engaged, it pre-secures the folding joints, ensuring structural rigidity is maintained during the folded state while still allowing easy folding when unlocked
3Ease of operation
If the locking mechanism is positioned at the bottom side of the arm rests, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the armrest structure itself. The locking member is integrated into the armrest assembly, combining the support function of the armrest with the locking function in a single unified component, thereby improving ease of operation without significantly increasing overall device complexity

AI summary
A recliner includes a folding frame including two arm rests, a chair frame coupling with the folding frame, and a locking mechanism. The chair frame includes a seat frame, a back frame, and a leg frame, wherein the chair frame is adapted to be selectively adjusted an inclination angle thereof to adjust the corresponding position of each of the seat frame, the back frame, and the leg frame in responsive to the sliding movement of the arm rest. The locking mechanism is provided at a bottom side of each of the arm rests to lock up the chair frame at the inclination angle.
