Unitary component for sectional seating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for furniture components that reduce costs while being easily assembled for sectional seating apparatus, as existing sectional furniture components require multiple pieces and extensive upholstery, leading to increased material and labor costs.
Innovation Solution
A unitary modular component with a single permanent and rigid frame, comprising a corner portion and an elongate lateral portion connected by a transverse foundation member, which reduces material usage and labor by eliminating duplicate end assemblies and allowing for common supporting members, enabling efficient assembly and reduced upholstery needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional separate piece sectional components are used, then structural integrity and assembly flexibility are maintained, but material usage and labor costs increase due to duplicate end assemblies and extensive upholstery requirements
Solution Approach 1:
The patent merges the corner portion and lateral portion into a single unitary frame component, eliminating the need for separate assembly of multiple pieces. This integration removes duplicate end assemblies and reduces the number of individual frame members required, directly addressing the technical contradiction by lowering material usage and manufacturing complexity while maintaining structural integrity.
Solution Approach 2:
The unitary frame component performs multiple functions simultaneously: it provides corner support, lateral support, and connection points for adjacent sections all within a single integrated structure. This multi-functionality eliminates the need for separate components to fulfill each function, reducing overall material usage and assembly complexity while maintaining the flexibility needed for various sectional configurations.
2Ease of manufacture
If unitary modular component with single frame is used, then material and labor costs are reduced, but structural integrity and rigidity must be maintained
Solution Approach 1:
By combining the corner and lateral portions into a single permanently joined unitary frame, the patent creates a rigid integrated structure that distributes loads more efficiently than separate components. This merging eliminates weak points at connection joints while reducing the total amount of material needed, thus maintaining strength while lowering costs.
Solution Approach 2:
The patent employs foundation members with cross-sections having different moment of inertia values to optimize structural performance. By strategically varying the material distribution within the frame members, the design achieves enhanced rigidity and load-bearing capacity in critical areas while using less material overall, resolving the contradiction between cost reduction and strength maintenance.
3Productivity
If traditional separate components are used, then assembly flexibility is maintained, but assembly time and complexity increase
Solution Approach 1:
The patent combines multiple separate components into a single unitary module that functions as an integrated corner and lateral support structure. This reduction in component count directly improves assembly efficiency by decreasing the number of parts that need to be handled, positioned, and fastened during installation, while the modular design maintains the flexibility needed for various sectional configurations.
Solution Approach 2:
The corner and lateral portions are permanently joined in advance during manufacturing to form a pre-assembled unitary frame. This preliminary action eliminates the need for on-site assembly of these components, reducing assembly time and complexity while ensuring precise alignment and structural integrity. The pre-configured unitary module can be directly installed as a complete assembly.
