Tool-Free Mattress Fixation Member for Adjustable Bed Bases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electric bed fixation members require tool assistance for assembly and disassembly, causing inconvenience, especially for consumers with disabilities, and may fail to securely fasten the mattress due to rust or need for sheet changes, leading to mattress movement issues.
Innovation Solution
A bed base with a fixation member featuring a horizontally extended part, an insertion part, and a stopper part that can be assembled and disassembled without tools, using insertion holes and bushings for easy attachment and detachment, ensuring the mattress is securely fixed without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting members are used to fasten the fixation member, then the fixation member can securely hold the mattress, but the assembly and disassembly require tool assistance which causes inconvenience and complexity
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a snap-fit mechanism. The mounting members are designed with elastic deformation capability, allowing them to be inserted into mounting holes and automatically lock into position through elastic recovery, eliminating the need for screwdrivers or other assembly tools.
Solution Approach 2:
The mounting members are designed to be self-installing through their elastic properties. When inserted into the mounting holes, they automatically deform and lock into place without requiring external tools or complex assembly procedures. The same mechanism allows for easy tool-free removal by applying outward force.
2Ease of operation
If traditional fixation members are used, then the mattress can be restrained, but the fixation member may become rusty and need replacement, or require detachment for sheet changes
Solution Approach 1:
The fixation member is designed as a separate, detachable component from the base frame. This segmentation allows the fixation member to be easily removed and replaced without affecting the base frame structure. The mounting members enable tool-free detachment, facilitating regular maintenance, cleaning, or replacement of the fixation member.
3Adaptability or versatility
If the electric bed functions are diversified with angle adjustments and massage functions, then the bed becomes more functional, but the mattress becomes easily moved toward the foot portion, bed head or side edge
Solution Approach 1:
The fixation member incorporates stopper parts with asymmetric geometry that extend beyond the horizontally extended part. These stopper parts are positioned to prevent the mattress from moving in specific directions (toward foot portion, bed head, or side edges) while allowing the necessary adjustments for bed functions. The asymmetric design provides directional restraint appropriate for each side of the mattress.

AI summary
A bed base capable of fixing mattress includes a base frame and a fixation member. The base frame includes at least one insertion hole. The fixation member includes at least one horizontally extended part, at least one insertion part downwardly extended from an end of the horizontally extended part, and a stopper part upwardly extended from the other end of the horizontally extended part. The insertion part is inserted into the insertion hole of the base frame, the horizontally extended part is placed on a top surface of the base frame, and the stopper part is used to stop at a side edge of the mattress. Therefore, the assembly or disassembly of the fixation member can be achieved without tool assistance.
