Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized functional fittings for box spring beds are inflexible, requiring different models for varying bed lengths and widths, leading to increased storage costs and transportation challenges due to their length exceeding standard pallet dimensions.
Innovation Solution
A modular design with a longitudinal beam that can be adapted to different bed sizes, featuring a lateral drive configuration and adjustable lift-up frames, allowing for efficient force distribution and reduced motor power requirements, enabling the use of shorter profiles and easier handling and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the longitudinal beam is configured as a continuous profile rail extending from head end to foot end, then the structural stability and force absorption capability are improved, but the device complexity and storage requirements increase due to different models needed for various bed lengths
Solution Approach 1:
The longitudinal beam is divided into a modular system consisting of a central beam section and extendable end sections. The central beam contains the drive mechanism, while end sections can be added or removed to accommodate different bed lengths, allowing the same base unit to serve multiple bed sizes without requiring completely different models.
Solution Approach 2:
The functional fitting incorporates adjustable and extendable components that allow the longitudinal beam configuration to adapt dynamically to different bed lengths. The end sections can be extended or retracted based on the specific bed size requirement, transforming a static single-length beam into a dynamic multi-length system.
2Adaptability or versatility
If the functional fitting length is increased to accommodate longer beds, then the adaptability to various bed sizes is improved, but the ease of transportation deteriorates as the length exceeds standard pallet dimensions
Solution Approach 1:
The functional fitting is segmented into a central beam unit and separate end sections that can be assembled together. This allows the components to be transported separately on standard pallets and then assembled on-site to the required length, avoiding the need to transport excessively long single-piece units.
Solution Approach 2:
The end sections are designed to nest within or attach to the central beam structure, allowing the entire functional fitting to be compacted into a smaller transport configuration that fits within standard pallet dimensions, while still providing the capability to extend to various bed lengths when assembled.
3Reliability
If the longitudinal beam is made more stable to absorb major forces, then the reliability is improved, but the weight and material usage increase
Solution Approach 1:
The beam structure is segmented into a central section with the drive mechanism and separate end sections. This segmentation allows the critical central portion to be optimized for strength and stability, while the end sections can be lighter, reducing the overall weight while maintaining the necessary structural integrity for force absorption.

Function Achieved in This Case
The solution provides a versatile, sturdy, and cost-effective motorized functional fitting that can be adapted to various bed sizes, reducing storage needs and transportation complexities while minimizing power consumption and maintaining structural stability.
Implementation Method 1
a linear drive extending or acting between the longitudinal beam and the lift-up frame is provided, which the linear drive converts a rotatory movement of an electric motor to a translation movement of a lifting tube
Implementation Method 2
a lift-up frame is rotatably hinged at a point of rotation to the longitudinal beam... upon actuation of the linear drive, the lift-up frame can be moved from a lowered rest position to a lift position that forms an acute angle with the beam longitudinal axis
