Elastomeric Protective Edge Assembly for Low-Labor Furniture Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic protective edges for furniture require skilled labor for affixing, increasing manufacturing costs due to complex installation methods and materials.
Innovation Solution
A unitary, molded, formed, and sized elastomeric plastic member that can be easily fitted and snapped into position, with options for additional features like hand grips, and affixed using simple methods like stapling, reducing labor costs and enabling decorative enhancements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional extruded plastic protective edges with spaced side flanges are used, then protection function is achieved, but skilled labor is required for affixing which increases manufacturing costs
Solution Approach 1:
The protective edge is divided into a body portion and separate affixing means (staples, adhesives, or self-adhesive backing), allowing the main protective function to be manufactured simply while the affixing method is simplified to basic stapling or adhesive application, eliminating the need for skilled labor to manipulate complex flange structures
Solution Approach 2:
Instead of designing the protective edge to be affixed through complex flange interlocking from the outside, the invention inverts the approach by providing affixing means that attach from the inside or behind the protective edge body, simplifying both manufacturing and installation processes
2Reliability
If multiple extruded sections are fitted and connected to form a single protective edge, then protection coverage is improved, but assembly complexity and labor requirements increase
Solution Approach 1:
Multiple extruded sections are merged into a single unitary molded protective edge that covers the entire perimeter or required area of the furniture piece as one continuous component, eliminating the need to fit and connect multiple sections while maintaining complete protection coverage
Solution Approach 2:
The unitary molded protective edge is designed to fit various furniture configurations (different shapes, sizes, and edge geometries) through a single versatile component that can be customized during molding, eliminating the need for multiple specialized sections
3Adaptability or versatility
If conventional protective edges are used, then basic protection is provided, but additional features like hand grips cannot be easily added
Solution Approach 1:
Additional features such as hand grips, decorative elements, or functional attachments are incorporated into the protective edge design during the initial molding process, so that features which would require complex post-manufacturing assembly are instead built-in from the start, simplifying manufacturing while enabling customization

AI summary
An elastomeric plastic material is molded by known methods to provide a formed, sized, shaped and self-contained, generally unitary, protective member for correspondingly shaped and sized unfinished, raw and the like edge of furniture or other devices which require protection or coverage, such that the protective member, because of its elastomeric characteristics, can be fitted or snapped into assembled position about such unprotected or unfinished edge and then easily fixed into assembled position, by conventional stapling using associated spaced flanges thereon, saving costs of material and labor. In the molding, additional modifications can be added such as a hand grip to facilitate movement of the furniture. The plastic protective member can be molded with a central cavity having an opening into which colored and non-colored fillers and/or braided rope can be inserted.
