Modular Rocker Chair Spring Assembly for Fast Tool-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rocker style chairs and chairs with pivoting seats have complex individual parts that are time-consuming and costly to manufacture and assemble, requiring significant resources and skilled labor for installation, with a high likelihood of errors and lost parts.
Innovation Solution
The use of modular components, such as a spring assembly with a rubber body and a landing bracket, allows for pre-assembled chair parts to be quickly assembled on-site without hand tools or fasteners, reducing installation time and labor requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional individual parts are used for rocker style chairs, then manufacturing and assembly can be performed with standard processes, but manufacturing time is extended and material usage is inefficient
Solution Approach 1:
The patent combines multiple individual parts (spring, caps, bushings, fasteners) into a single pre-assembled spring assembly unit. This merging of components into a modular unit allows for more efficient manufacturing through specialized processes like rubber injection molding, reducing overall manufacturing time while improving material usage efficiency.
2Adaptability or versatility
If complex individual parts are assembled on-site, then chair components can be customized, but assembly time increases and skilled labor is required
Solution Approach 1:
The spring assembly is pre-assembled at the manufacturing site before delivery to the installation location. This preliminary action includes attaching caps, bushings, and fasteners to the spring in a controlled environment, which reduces on-site assembly time and minimizes the need for skilled labor during installation while maintaining design flexibility.
3Strength
If traditional assembly methods with fasteners are used, then secure connections are achieved, but installation requires hand tools and skilled labor
Solution Approach 1:
The spring assembly is designed as a self-contained unit where all connections are pre-established during manufacturing. The assembly includes integrated fasteners and locking mechanisms that require no additional tools or skilled labor for installation, allowing facility staff to easily install the chairs while maintaining secure connections through the pre-assembled structure.
