Problem
Conventional electric beds with vibrating motors face challenges in securely mounting and installing the motors, and in effectively dissipating heat generated during prolonged use, which can lead to overheating and premature aging of components.
Innovation Solution
An electric bed design featuring a bed support with a hollow portion, a cushion container with heat dissipating holes, and a retaining belt that securely fixes the vibrating motor and enhances heat dissipation through strategically placed holes for ambient airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If foam materials are used to absorb vibrations from the vibrating motor, then vibration absorption is improved, but heat dissipation deteriorates and heat accumulates
Solution Approach 1:
The cushion container is designed with multiple heat dissipating holes formed directly in the foam material, creating a porous structure that allows heat to pass through while maintaining the vibration absorption properties of the foam
Solution Approach 2:
The cushion container acts as an intermediary between the vibrating motor and the external environment, providing both vibration absorption through the foam material and heat dissipation through the strategically placed holes
2Duration of action of moving object
If the vibrating motor operates for a long period of time, then massage function is improved, but heat accumulation increases and motor lifespan decreases
Solution Approach 1:
The heat dissipating holes enable continuous heat removal during prolonged motor operation, ensuring that the massage function can operate for extended periods without heat accumulation damaging the motor
Solution Approach 2:
The design converts the harmful heat byproduct of prolonged motor operation into a manageable issue by providing dedicated heat dissipation pathways, allowing the motor to run longer safely
3Object-affected harmful factors
If foam material is used for vibration absorption, then vibration isolation is improved, but heat insulation increases and heat dissipation worsens
Solution Approach 1:
The foam material is designed with integrated heat dissipating holes that create a porous structure, allowing thermal energy to pass through while the foam matrix continues to absorb vibrations effectively

AI summary
An electric bed includes a bed support, a cushion container, a vibrating motor, and a retaining belt. The bed support has a hollow portion. The cushion container includes a main body having a top portion received in the hollow portion, a chamber provided inside the main body, and at least one first heat dissipating hole communicated with the chamber to an ambient environment. The vibrating motor is disposed in the chamber of the cushion container. The retaining belt is disposed to the bed support and attached on a bottom edge of the cushion container to fix the cushion container to the bed support. As a result, the vibrating motor can be firmly mounted by a simple way to achieve convenient assembly, and the heat generated by the vibrating motor due to operation for a long period of time can be effectively dissipated.
