Adjustable mattress frame and a method for adjusting the frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adjustable beds are heavy, cumbersome, and expensive due to their use of heavy motors and durable frames, requiring designated mattresses and limited lying postures, with high manufacturing, shipping, and installation costs, and they lack ergonomic flexibility.
Innovation Solution
An adjustable mattress frame with pivotally connected areas and adjustable cables or links, allowing for various lying positions through angle changers, including back and head cables and legs cables, with adjusters to change lengths and angles between areas, supported by a lightweight design using cables and rotors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy motors and durable frames are used in adjustable beds, then reliability and structural strength are improved, but weight and device complexity increase significantly
Solution Approach 1:
The patent replaces heavy motors with a cable-driven mechanical system using pulleys and cables. The adjustment mechanism uses cables routed through pulleys attached to the frame and mattress, allowing manual or motorized tension adjustment without requiring heavy-duty motors. This substitution dramatically reduces weight while maintaining structural reliability through the cable-tensioned framework.
Solution Approach 2:
The patent employs a flexible mattress assembly that can bend and conform to adjustable positions without requiring a rigid heavy frame. The mattress uses flexible materials and a segmented structure that allows it to adapt to different angles and positions, reducing the need for heavy supporting structures while maintaining durability and reliability.
2Reliability
If heavy motors and mechanisms are used for adjustment, then adjustment reliability is improved, but ease of operation and portability deteriorate
Solution Approach 1:
The patent replaces heavy motorized mechanisms with a cable-pulley system that can be adjusted manually or with minimal motor assistance. The cables run through pulleys attached to the frame and mattress, allowing smooth adjustment of mattress angle and position. This reduces the power requirements and overall weight, making the bed easier to move and operate while maintaining reliable adjustment capability.
3Strength
If a durable heavy frame is used, then structural strength is improved, but manufacturing cost and shipping cost increase
Solution Approach 1:
The patent uses a flexible mattress assembly with a segmented structure that can bend and adapt to different positions. This flexible design allows the use of lighter materials and reduces the need for heavy reinforcing structures, lowering manufacturing costs and material requirements while maintaining sufficient strength for support.
Solution Approach 2:
The mattress is divided into multiple segments or zones that can independently adjust or flex. This segmentation allows the structure to achieve required strength and flexibility with lighter materials, reducing overall frame weight and manufacturing cost while maintaining structural integrity through the distributed segmented design.
4Adaptability or versatility
If traditional adjustable bed mechanisms are used, then lying position adjustment is achieved, but ergonomic flexibility and variety of postures are limited
Solution Approach 1:
The flexible mattress assembly can bend and conform to various angles and positions, enabling a wide range of ergonomic postures including zero gravity position, elevated head position, and bent knee positions. The flexibility of the mattress material and segmented structure allows it to adapt to different body contours and positions without requiring complex mechanical mechanisms for each specific posture.
Solution Approach 2:
The patent employs a dynamic adjustment system where the mattress can be positioned at various angles along its length, with different sections adjustable independently. The cable-pulley mechanism allows continuous adjustment rather than fixed positions, enabling users to find optimal ergonomic positions dynamically. This dynamic capability provides versatile posture options without proportionally increasing mechanism complexity.
