Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed base slat suspension devices require specialized machinery for manufacturers to drill and align fixings, making them difficult for consumers to assemble quickly and correctly, and do not allow for adjustments in slat spacing or movement.
Innovation Solution
A device comprising multiple gussets connected by a flexible connecting strip with undulations, allowing relative movement and easy handling, enabling faster factory pre-assembly and consumer installation, with adjustable spacing and deformation to compensate for assembly faults and accommodate different bed types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If gussets are rigidly fixed to the bed base frame using specialized drilling machines, then positioning precision and alignment are improved, but assembly complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into multiple modular gussets (at least three gussets) that can be independently positioned and assembled. Each gusset serves as an independent module that receives slat ends and connects to the bed base frame, allowing for simplified assembly without requiring complex pre-alignment machinery.
Solution Approach 2:
The gussets are designed with movable connections to the bed base frame, allowing them to be positioned and adjusted during assembly. This dynamic positioning capability enables consumers to assemble the device without specialized drilling machines, while still achieving adequate alignment through the inherent flexibility of the connection mechanism.
2Manufacturing precision
If gussets are rigidly fixed with precise alignment, then slat parallelism is improved, but assembly time and consumer difficulty increase
Solution Approach 1:
By segmenting the support structure into multiple independent gussets, each gusset can be quickly attached to the frame and positioned independently. This modular approach eliminates the need for time-consuming precision alignment procedures, allowing consumers to assemble the bed base rapidly while maintaining adequate slat parallelism through the geometric design of the gussets.
Solution Approach 2:
The device is designed to be self-assembling by the consumer without requiring specialized equipment or expert knowledge. The gussets incorporate features that enable easy attachment to the bed base frame and automatic self-alignment, allowing the consumer to achieve proper slat parallelism through simple assembly operations rather than complex adjustment procedures.
3Ease of manufacture
If fixed spacing between gussets is used, then manufacturing simplicity is improved, but adaptability to different bed configurations is reduced
Solution Approach 1:
The connection mechanism between gussets and the bed base frame is designed to be movable rather than fixed, allowing the spacing between gussets to be adjusted during assembly. This dynamic spacing capability enables the same device to accommodate different bed configurations and lengths, including beds with liftable heads or feet, while maintaining manufacturing simplicity through standardized gusset components.
Solution Approach 2:
The device allows for parameter changes in the spacing between gussets to adapt to different bed configurations. The connection mechanism enables variation in the distance between adjacent gussets, allowing manufacturers to produce a standardized device that can be configured for different bed lengths and types, including those requiring additional slats in specific regions or accommodating liftable sections.
4Stability of the object's composition
If rigid connecting strips are used between gussets, then structural stability is improved, but ability to compensate for assembly faults is reduced
Solution Approach 1:
The connecting strips or means joining adjacent gussets are designed with flexible or movable connections that allow relative movement between gussets. This dynamic connection maintains structural stability for normal use while providing the flexibility to accommodate assembly tolerances and correct positioning faults, enabling the device to self-adjust during assembly without requiring precise pre-alignment.
5Manufacturing precision
If multiple separate blocks are used for slat support, then positioning precision is improved, but handling difficulty and assembly time increase
Solution Approach 1:
Multiple gussets that would traditionally be separate blocks are merged into a single integrated device with connecting means joining them together. This combined structure maintains the positioning precision of individually placed blocks while dramatically improving handling ease, as the consumer can install one unified device rather than managing multiple separate components. The connecting strips enable the gussets to move relative to each other, preserving positioning flexibility while simplifying assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates rapid and error-tolerant assembly by consumers, allows for adjustable slat spacing, and provides comfort similar to factory-mounted blocks, accommodating various bed lengths and types, including those with liftable heads and feet.
Implementation Method 1
Thanks to the deformability of the connecting section, in particular by elastic deformation, the mobility of a gusset with respect to the gusset which is directly adjacent to it, is permitted and allows any defects which are generally due to the poor positioning of the gussets to be corrected.
