Multi-Height Bed Frame Synchronization for Twin Lifting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to synchronize the lifting of twin bed frames in hotel rooms for maintenance personnel, making it difficult to adjust both beds to comfortable heights for cleaning and changing bedding efficiently.
Innovation Solution
A synchronized bed lifting device with a system of electronic controllers and electric actuators allows for independent or simultaneous control of multiple bed frames, enabling precise height adjustment and stabilization, powered by a rechargeable battery system with remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent control mechanisms are used for each bed frame, then each bed can be adjusted to different heights, but the beds cannot be synchronized during lifting operations
Solution Approach 1:
The patent combines multiple control boxes into a unified system where a master control box coordinates with slave control boxes. The master box receives a single lifting command and distributes synchronized control signals to all slave boxes, enabling coordinated lifting of multiple bed frames while preserving individual height adjustment capabilities through the parallelogram mechanism.
Solution Approach 2:
The master control box acts as an intermediary between the operator and multiple slave control boxes. It receives the lifting command, processes it, and sends coordinated signals to all slave boxes simultaneously, ensuring synchronized operation without requiring the operator to control each bed individually.
2Adaptability or versatility
If separate control boxes are used for each bed, then independent operation is possible, but the system complexity increases
Solution Approach 1:
The control system dynamically switches between independent and synchronized operation modes. The master control box can operate autonomously for single-bed adjustments, or coordinate with slave boxes for synchronized multi-bed operations, adapting its behavior based on operational requirements without requiring separate fixed configurations.
3Productivity
If manual lifting is performed without synchronization, then simple mechanisms are sufficient, but maintenance efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical coordination with an electronic control system. The master and slave control boxes use electronic signals to synchronize lifting operations, eliminating the need for manual coordination between multiple operators and significantly improving maintenance efficiency while managing complexity through electronic rather than mechanical means.
