Solution Overview

Problem

Existing bed conversion systems in hotels and homes lack automation, stability, and ergonomic design, requiring manual intervention and visible mechanical elements that affect aesthetics and increase effort for cleaning staff.

Innovation Solution

A motorized system with hidden electric motors and displacement guides allows lateral and lifting movements of bed frames, controlled remotely, ensuring stability, safety, and ease of use, with integrated obstacle detection and compatibility with lifting mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual mechanisms are used for bed conversion, then device complexity is reduced, but ease of operation deteriorates due to required manual intervention

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated motorized system. Electric motors are integrated into the bed frame structure to automatically perform lateral displacement and lifting movements, eliminating the need for manual intervention while maintaining a clean aesthetic appearance through hidden motor placement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Shape

If visible mechanical elements are used for bed conversion, then ease of manufacture is improved, but aesthetics deteriorate due to visible mechanisms

Engineering Contradiction:
Improveaesthetic designVSAvoidease of manufacture
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent embeds the electric motors within the bed frame structure itself, nesting the mechanical components inside the aesthetic housing. This allows the motors to be hidden from view while remaining functional, achieving both aesthetic appeal and manufacturing feasibility through integrated design.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If fixed bed structures are used, then stability is improved, but adaptability deteriorates due to inability to convert configurations

Engineering Contradiction:
ImproveadaptabilityVSAvoidstability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent transforms the static bed structure into a dynamic system with motorized components that enable automatic lateral displacement and lifting. The bed frame includes movable sections that can be automatically positioned to convert between single and double bed configurations, providing both adaptability and operational stability through controlled movement mechanisms.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If double bed width is maintained for easy cleaning access, then ease of operation improves, but harmful factors increase due to ergonomic problems for workers

Engineering Contradiction:
Improveease of operationVSAvoidergonomic problems
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent enables the bed structure to dynamically change width through motorized lateral displacement of bed sections. This allows the bed to be in a narrow single-bed configuration during use (reducing ergonomic risks) and automatically expand to a wider double-bed configuration during cleaning operations (improving worker access and comfort).

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to a motorised system for converting between single beds and a double bed, comprising two bed frames, each formed by a structure and a mattress base, wherein each bed frame is equipped with at least two electric motors arranged in parallel and housed inside the structure. Said motors allow the lateral displacement of the structure with respect to the floor and are connected to a transmission system made up of gears and displacement guides, allowing the mattress base to perform an independent lifting movement with respect to the structure. Said motors are also configured to allow the mattress base to be able to be lifted independently or simultaneously, adapting to user's needs.
