Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional iron sofa frame production process is labor-intensive, inefficient, and costly, with high material consumption and complexity in assembly, leading to issues such as poor connection stability, environmental concerns, and difficulty in achieving standardized and automatic production.
Innovation Solution
An iron sofa frame structure featuring a base with oppositely disposed supporting plates connected by driving link sets and elastic bearing pieces, eliminating the need for an additional seat-wrapped frame, which simplifies the assembly and production process, reduces material usage, and enhances connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wooden seat-wrapped frame is used to support the soft package, then the supporting area is increased and comfort is improved, but wood resource consumption increases and environmental protection is compromised
Solution Approach 1:
The patent merges the seat-wrapped frame structure with the iron sofa frame by directly welding supporting angle steels to the iron frame. This integration eliminates the need for separate wooden frames while maintaining the supporting area and comfort functions through the iron angle steels that provide both structural support and mounting surfaces for serpentine springs.
2Ease of operation
If a wooden seat-wrapped frame is used, then connection convenience is improved, but connection stability deteriorates and defects are easy to generate
Solution Approach 1:
The patent extracts the wooden frame component entirely and replaces it with iron angle steels that are directly welded to the iron sofa frame. This elimination of the intermediate wooden frame removes the connection interface problems between different materials, ensuring both connection convenience through direct attachment and connection stability through welding and rigid metal-to-metal joints.
3Ease of manufacture
If a wooden seat-wrapped frame is used, then the production process is simple and suitable for manual production, but production efficiency is low and standardized production is difficult to realize
Solution Approach 1:
The patent changes the material parameter from wood to iron angle steels, which enables welding connections and standardized fabrication. This material substitution allows for pre-fabrication of frame components, automated welding processes, and consistent quality control, thereby improving production efficiency while maintaining ease of manufacture through standardized procedures.
4Area of stationary object
If a wooden seat-wrapped frame is used, then the supporting area is increased, but the service life is shortened due to pest reproduction
Solution Approach 1:
The patent changes the material parameter from organic wood to inorganic iron, which is immune to pest reproduction. The iron angle steels maintain the required supporting area while providing indefinite service life free from biological degradation, rot, or insect damage that plagues wooden frames.
5Productivity
If an iron seat-wrapped frame is used, then production efficiency is improved, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent merges the seat-wrapped frame structure with the main iron sofa frame by directly welding supporting angle steels to the frame. This integration reduces the number of separate parts compared to an assembled iron frame system, simplifies assembly to primarily welding operations, and maintains production efficiency through standardized fabrication processes.

AI summary
Provided is an iron sofa frame structure provided with a base, two supporting plates oppositely disposed, configured to support a soft package and be connected with a sofa fabric and two driving link sets respectively configured to connect the two supporting plates to the base, wherein a front rod and a rear rod are correspondingly disposed at intervals between the two supporting plates, and several elastic bearing pieces for bearing the soft package are disposed between the front rod and the rear rod. The supporting assembly is directly combined to the iron sofa frame structure, so that a structure in which an additional seat-wrapped frame is introduced to support the soft package is rejected, an existing iron sofa frame structure and a production process of an iron sofa frame are simplified, the assembling and production efficiencies are increased, materials are saved, and the cost is reduced.
