Solution Overview

Problem

Existing bed lifting systems lift the mattress and base together, making it difficult to change bed linen, and lack retainers to secure the linen in place during the process.

Innovation Solution

A device with a platform that separates the mattress from the base and a system of retainers that secure the bed linen, allowing easy linen changing and reducing manual lifting efforts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bed lifting system lifts the mattress and base together, then the structural integrity is maintained, but the ease of operation for bed linen changing deteriorates

Engineering Contradiction:
Improveease of bed linen changingVSAvoidcomplexity of lifting system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lifting system is segmented into two independent functional components: a base lifting mechanism and a mattress separating platform. The platform can be inserted between the mattress and base, allowing the mattress to be lifted and separated independently from the base when the bed is in the lifted position, thereby facilitating bed linen changing without requiring manual lifting of the mattress corners

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A separating platform acts as an intermediary element between the lifting arms and the mattress. This platform includes stems that engage with the lifting arms and provide a surface for the mattress to rest on during separation, enabling the mattress to be lifted clear of the base while maintaining structural support throughout the operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the mattress is separated from the base for linen changing, then the ease of operation improves, but the stability of the mattress position deteriorates

Engineering Contradiction:
Improveease of bed linen changingVSAvoidstability of mattress position
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The retainers are designed as dynamic elements that automatically adjust their position based on the bed's state. When the bed is lifted, the retainers extend outward to secure the bed linen; when the bed is lowered, the retainers retract inward to avoid interference with the base. This dynamic behavior maintains mattress stability during separation while ensuring proper positioning during normal use

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retainers are positioned and configured in advance to automatically engage with the bed linen when the mattress is separated from the base. The retainers are pre-positioned on the separating platform and spring-loaded to extend outward upon lifting, securing the linen before any displacement can occur during the linen changing process

Inventive Principle:
Principle #10Preliminary action

3Reliability

If retainers are extended to secure bed linen, then the reliability of linen positioning improves, but the device complexity increases

Engineering Contradiction:
Improvereliability of linen positioningVSAvoidcomplexity of retainer system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retainers are designed as self-actuating components that automatically extend and retract based on the bed's position. The spring-loaded mechanism causes the retainers to extend outward when the bed is lifted, securing the bed linen without requiring manual intervention. When the bed is lowered, the retainers automatically retract inward, eliminating the need for manual adjustment or complex control systems

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The retainer system is integrated with the separating platform structure, combining multiple functions into a single component. The retainers are mounted on the platform's side edges and work in conjunction with the lifting mechanism, eliminating the need for separate linen securing devices and reducing overall system complexity despite adding linen retention functionality

Inventive Principle:
Principle #5Merging (Combining)
