Hook Assembly System for Modular Footrest Attachment to Furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of an assembly system for attaching and detaching accessories, such as footrests, to furniture items like chairs with ease, and existing systems do not allow for modular attachment and adjustment.
Innovation Solution
A footrest assembly system featuring a mounting frame with brackets, a recliner frame with pivotable portions, and an actuator assembly using a gas spring to adjust the recliner angle, along with a hook assembly for secure attachment to furniture items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a footrest assembly is permanently integrated to a chair, then structural stability is improved, but adaptability and ease of detachment deteriorate
Solution Approach 1:
The footrest assembly is divided into separate modular components: a mounting frame that attaches to the chair, a recliner frame with footrest, and an actuator assembly. These segments can be independently assembled and detached through the hook assembly mechanism, providing both stability when connected and adaptability when separated.
Solution Approach 2:
The system transitions from a static permanent attachment to a dynamic removable connection. The hook assembly with locking mechanism allows the footrest assembly to be easily attached and detached, while the gas spring actuator enables dynamic adjustment of the recliner angle during use, providing both stability and adaptability.
2Ease of operation
If a complex assembly system is designed to allow easy attachment and detachment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The hook assembly serves as an intermediary component that simplifies the attachment and detachment process. It provides a user-friendly interface with a locking mechanism that secures the footrest to the chair during use but allows easy release when needed, bridging the gap between simple operation and secure connection without requiring complex systems.
3Adaptability or versatility
If the footrest assembly is designed with multiple adjustable positions, then adaptability is improved, but interference with other chair functions may increase
Solution Approach 1:
The mounting frame is designed to integrate with the chair's existing structure, and the recliner frame combines the footrest support with the angle adjustment mechanism. By merging these functions into a unified assembly that attaches through the hook mechanism, the system provides multiple recliner angle positions without creating excessive interference with other chair functions.
