Supporting frame of electric bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available electric beds lack a fixed connection between the bed frame and the electric bed, leading to potential pinching hazards when the bed frame moves relative to the electric bed, posing risks to users and pets.
Innovation Solution
A supporting frame for electric beds that connects a lateral board of the bed frame with a base and an extended supporter, featuring a transverse portion and a connecting portion, which prevents the lateral board from moving towards the electric bed, thereby preventing pinching incidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bed frame is made movable relative to the electric bed for ease of installation and adjustment, then the ease of operation is improved, but the safety is worsened due to pinching hazards
Solution Approach 1:
The patent introduces an extended supporter as an intermediary component between the bed frame and the electric bed base. This extended supporter includes a transverse portion that extends from the base toward the lateral board, creating a protective barrier that prevents direct contact between the user and the pinching zone. The connecting portion of the extended supporter attaches to the lateral board, establishing a controlled connection that maintains safety while allowing necessary movement.
Solution Approach 2:
The supporting frame is divided into distinct functional segments: a base that contacts the electric bed, supporting portions that provide structural support, and extended supporters that specifically address the safety issue. The extended supporter itself is segmented into a transverse portion (for safety spacing) and a connecting portion (for attachment), allowing each segment to perform its specific function independently.
2Object-affected harmful factors
If the bed frame is fixed to prevent pinching hazards, then the safety is improved, but the ease of operation deteriorates due to reduced adjustability
Solution Approach 1:
The extended supporter acts as a mediator that provides safety without complete fixation. By positioning the transverse portion between the base and the lateral board, it creates a controlled interface that prevents pinching while still allowing the lateral board to move relative to the base for adjustment purposes.
Solution Approach 2:
The supporting frame structure is designed to automatically maintain safe spacing through its geometric configuration. The transverse portion's extension from the base creates inherent spacing that self-regulates the distance between the lateral board and the electric bed, providing passive safety without requiring active control mechanisms.
3Device complexity
If the transverse portion is positioned close to the lateral board for compact design, then the device complexity is reduced, but the safety deteriorates due to increased pinching risk
Solution Approach 1:
The extended supporter applies the principle of local quality by concentrating the safety function in the transverse portion's specific geometric configuration. The transverse portion extends far enough to create the necessary safety spacing at the critical interface between the lateral board and the electric bed, while other portions of the structure maintain compact dimensions for aesthetic and space considerations.

AI summary
A supporting frame of an electric bed, which is used to be connected with a lateral board, includes a base, a supporting portion disposed on the base, and an extended supporter. At least a part of the supporting portion is movable relative to the base. The lateral board is adjacent to the edge of the supporting portion. The extended supporter has a transverse portion extended from the base toward the lateral board, and a connecting portion located at a free end of the transverse portion. The transverse portion and the supporting portion have a distance therebetween. The connecting portion is used to be connected with the lateral board, so that the lateral board of the bed frame is fixed by being connected with the base by the extended supporter, and the user is prevented from being pinched.
