Modular Rocker Chair Assemblies for Fast Tool-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rocker style chairs with pivoting seats face challenges in manufacturing and installation due to complex individual parts, time-consuming assembly, high resource requirements, and the need for skilled labor, which increases costs and error likelihood.
Innovation Solution
The introduction of modular components such as left-hand and right-hand standard assemblies, chair seat assemblies, and chair back assemblies that can be pre-assembled off-site, allowing for efficient on-site installation without hand tools or fasteners, and featuring designs like over-travel bolt nut receptacles and fastener head receptacles to prevent rotation, facilitating easier assembly and reducing labor needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rocker style chairs are assembled from individual parts on site, then installation flexibility is maintained, but assembly time and resource requirements increase significantly
Solution Approach 1:
The chair is divided into modular components (seat assembly, backrest assembly, leg assemblies) that can be pre-assembled and tested separately, then quickly connected on-site using simple connection mechanisms, resolving the conflict between assembly speed and complexity
Solution Approach 2:
Complex sub-assemblies are pre-assembled and pre-tested at the manufacturing site before delivery, so that on-site installation only requires simple connection operations rather than complete assembly from individual parts, improving assembly speed while managing complexity
2Area of stationary object
If complex components are used to achieve pivoting seat functionality, then space utilization improves, but manufacturing and assembly time increase
Solution Approach 1:
The seat assembly incorporates a pivot mechanism that allows automatic rotation between horizontal (occupied) and vertical (unoccupied) positions, enabling space-saving configuration while using standardized mechanical components that can be efficiently manufactured and assembled
Solution Approach 2:
The connection mechanisms and structural components are designed to serve multiple functions (structural support, pivoting motion, easy disassembly), reducing the need for specialized complex parts and enabling efficient manufacturing and assembly
3Manufacturing precision
If traditional installation methods are used requiring skilled labor and hand tools, then installation precision is maintained, but labor costs and error likelihood increase
Solution Approach 1:
The connection mechanisms are designed to be self-aligning and self-locking, allowing installers to connect components without specialized tools or extensive training, maintaining precision while greatly simplifying the installation process
Solution Approach 2:
Simple connection intermediaries (connection elements, mounting brackets) are designed with features that guide proper alignment and provide foolproof installation, reducing errors and eliminating the need for skilled labor while maintaining installation precision
