Solution Overview
Problem
Existing bed structures with lifting mechanisms require user effort to move the mattress base between positions, limit access due to insufficient height, and are not suitable for confined spaces, with complex and error-prone operation.
Innovation Solution
A bed structure with a reversible moving mechanism using reciprocally hinged levers and a linear actuator that allows the mattress base to move from a closed horizontal position to a tilted and then an upper horizontal position with a single continuous movement, eliminating user effort and ensuring the mattress base remains fully contained within the base container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a lifting mechanism with elastic elements or electric actuators is used to raise the mattress base, then the mattress base can be lifted with minimum effort, but user effort is still required to move the mattress base between stable positions
Solution Approach 1:
The mechanism uses the weight of the mattress base itself as the counterweight, allowing the system to automatically balance and move between positions without requiring external effort from the user. The mattress base's gravity creates the necessary counterbalancing force that enables effortless operation.
Solution Approach 2:
The invention employs a counterweight system where the mattress base's own weight is utilized to balance the mechanism. The articulated quadrilateral configuration allows the mattress base to act as its own counterweight, eliminating the need for additional counterweights or continuous external force application.
2Ease of operation
If the mattress base is lifted vertically to a horizontal position, then access to the container below is permitted, but the height reached is insufficient for convenient access
Solution Approach 1:
Instead of purely vertical lifting, the mechanism tilts the mattress base at an angle, creating diagonal access space. This dimensional change allows the container volume to be accessed from above at an inclined angle, providing sufficient clearance and convenience without requiring increased container height.
3Adaptability or versatility
If hybrid lifting mechanisms with two degrees of freedom are used, then the mattress base can reach both tilted and horizontal positions, but the operation becomes complex and error-prone
Solution Approach 1:
The movement is divided into two sequential phases: first tilting the mattress base to access the container, then lifting to a horizontal position for bed making. This segmentation of motion into distinct phases simplifies the control mechanism while maintaining the versatility of reaching multiple positions.
Solution Approach 2:
The mechanism transitions from a static balanced position to dynamic movement through a single actuation action. The articulated quadrilateral allows the system to dynamically shift between configurations, achieving both tilted and horizontal positions through one continuous motion rather than requiring complex multi-stage control.
4Ease of operation
If the mattress base protrudes frontally beyond the container volume, then access to the container is improved, but the bed structure requires larger bedroom spaces
Solution Approach 1:
The mattress base nests within the container boundaries when in the closed position, and during operation, it tilts inward rather than protruding outward. This nesting configuration allows full container access while maintaining a compact footprint that fits within standard bedroom spaces.
