Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable upholstery devices lack the ability to integrate a loading/relieving mechanism within a common casing, limiting their functionality and appearance as conventional mattresses without electromotive adjustment devices.
Innovation Solution
Incorporating an electromechanical loading/relieving device with an electric motor connected to pressure elements, allowing for adjustable pressure loading or relief, and a control device for manual operation, which can act on multiple spring elements in a timed sequence to achieve massage-like effects, while maintaining a low profile and simple construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a loading/relieving device is integrated into the common casing of an adjustable upholstery device, then the functionality is expanded to include massage functions, but the device complexity increases
Solution Approach 1:
The loading/relieving device is integrated into the common casing that already houses the electromotive adjustment device, merging multiple functions into a single housing structure. This combines the adjustment mechanism and the loading/relieving mechanism in one unified housing, expanding functionality while managing complexity through integration rather than separate components.
Solution Approach 2:
The common casing serves multiple functions: it houses the electromotive adjustment device, accommodates the loading/relieving device, and provides the structural framework for the entire upholstery system. This multi-functional design allows the device to perform both adjustment and massage functions without proportionally increasing complexity.
2Measurement precision
If an electromechanical loading/relieving device is used with multiple pressure elements, then pressure control precision is improved, but the device complexity increases
Solution Approach 1:
The loading/relieving device is divided into multiple independent pressure elements (first pressure element and second pressure element) that can be controlled separately. Each pressure element can be adjusted independently to apply pressure to different spring elements, enabling precise pressure control at multiple locations without requiring a single complex high-precision mechanism.
Solution Approach 2:
The pressure elements are designed to be dynamically controllable through the electromechanical mechanism, allowing the system to adjust pressure distribution in real-time. The control device can vary the pressure applied by each element independently, creating dynamic pressure patterns that improve control precision while using simple mechanical components.
3Ease of repair
If the pressure elements are loosely connected to spring elements, then ease of repair is improved, but the reliability of pressure transmission may worsen
Solution Approach 1:
The pressure elements are pre-positioned to loosely engage with the spring elements, allowing them to make contact when needed without permanent attachment. This preliminary positioning ensures that when pressure is applied, the elements naturally align and transmit force effectively, while maintaining the ability to be easily removed or replaced for maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the functionality of adjustable upholstery devices by enabling pressure loading or relief within a conventional mattress appearance, providing a massage effect and simplifying maintenance with a loose connection between pressure elements and spring elements, thus offering improved user control and ease of assembly.
Implementation Method 1
The loading and relieving device is an electromechanical loading and relieving device. The loading and relieving device has at least one electric motor which is operatively connected to at least one pressure element
Implementation Method 2
spring elements are arranged, on which the padding is supported when the support device is used
