Arrangement with a plurality of spring elements for a cushion support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrangements of spring elements for upholstery pads face challenges in simple assembly and efficient mounting, particularly in combining multiple spring elements to form a cushion base.
Innovation Solution
The arrangement features spring elements connected via integrally formed one-piece connecting elements, allowing for easy mounting and combination, with spring arms between the base and support plate that can be designed to open into the base or support plate directly or via connecting pieces, enabling varying spring constants and hardness levels by combining elements with different spring constants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring elements are fixed separately to the base using screws or nails, then the spring elements are securely attached, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple spring elements with individual bases into a single modular unit where several spring elements are arranged side-by-side and fixed to a common base plate as one assembly. This merging reduces the number of separate fastening operations required, thereby decreasing assembly time while maintaining secure attachment of each spring element through the unified base structure.
Solution Approach 2:
The patent implements preliminary action by pre-assembling multiple spring elements onto a base plate before final installation. The spring elements are positioned and secured to the base plate in advance, creating a pre-fabricated modular unit that can be quickly installed as a complete assembly, thus reducing on-site assembly time and complexity.
2Manufacturing precision
If multiple spring elements are assembled individually, then each element can be precisely positioned, but the overall assembly process becomes inefficient
Solution Approach 1:
The patent merges multiple spring elements into a coordinated assembly on a shared base plate, allowing precise positioning to be achieved through the structured arrangement of the modular unit rather than through individual positioning operations. The base plate provides a reference framework that ensures correct positioning of all spring elements simultaneously.
Solution Approach 2:
The patent segments the cushion base into modular units, each containing a specific number of spring elements arranged in a predetermined pattern. This segmentation allows for standardized manufacturing of each module with precise positioning built-in, while multiple modules can then be efficiently assembled to create the complete cushion base, improving overall productivity.
3Stability of the object's composition
If spring elements are connected using separate connecting elements like clamps or plug-in fasteners, then the relative position of spring elements is secured, but the device complexity increases
Solution Approach 1:
The patent merges the function of connecting elements into the base plate structure itself. The base plate is designed with integrated features that directly secure the spring elements in their relative positions without requiring separate clamps or plug-in fasteners. This integration maintains the stability of spring element positioning while eliminating the additional components and assembly steps that would increase device complexity.
