Chaise Lounge Backrest Adjustment with Remote Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor chaise lounge chairs require users to disrupt their relaxing position to adjust the backrest angle, and hospitality staff face exhaustion when resetting multiple chairs to a flat position, as they must either lie down or reach awkwardly to operate the locking mechanism.
Innovation Solution
A chaise chair design featuring a mount and linkage system with a locking mechanism that allows the backrest to be pivoted between lowered and raised positions, equipped with a release mechanism for easy adjustment, and a gas spring assembly for spring-assisted angular control, enabling users to change the backrest angle without leaving their position and allowing staff to efficiently reset multiple chairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional brace assembly is used to hold backrest at predetermined angles, then the backrest can be held at stable angles, but the user must get up and walk to the back of the frame to adjust the angle
Solution Approach 1:
A cable mechanism serves as an intermediary to transmit the user's pulling action from the side of the chair to the brace assembly at the back of the frame, enabling remote operation without requiring the user to physically reach the adjustment mechanism
Solution Approach 2:
The adjustment mechanism is accessed from a different spatial dimension - the user pulls a cable from the side of the chair rather than reaching to the back of the frame, changing the operational dimension from longitudinal (back of chair) to lateral (side of chair)
2Productivity
If staff manually reset multiple chaise lounge chairs to flat position, then the chairs can be realigned for hospitality settings, but the staff become exhausted from the repetitive task
Solution Approach 1:
The spring bias system provides self-service by automatically returning the backrest to the upright position when the lock is released, eliminating the need for staff to physically push or lift the heavy backrest for each chair
Solution Approach 2:
The spring mechanism acts as a counterweight system, storing energy when the backrest is raised and automatically releasing it to return the backrest to the lowered position, reducing the physical effort required by staff

AI summary
A chaise chair includes a frame, a main seat attached to the frame, a backrest pivotally attached to the frame, and a mount connected with and selectively movable with respect to the frame. The backrest is pivotal between a lowered position and a raised position. A locking mechanism is associated with the mount and is operable between a locked state in which the mount is precluded from movement with respect to the frame and an unlocked state in which the mount is movable with respect to the frame. A linkage connects with the mount and the backrest and is configured such that movement of the mount with respect to the frame results in pivotal movement of the backrest with respect to the frame. A release mechanism is operatively associated with the locking mechanism so as to change the locking mechanism from the locked state to the unlocked state.
