Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient transfer devices, such as Hoyer Lifts, cause strain on operators, are costly, error-prone, and often result in injuries or death, failing to support two-sided functionality and efficient object transfer without manual manipulation.
Innovation Solution
A transfer device with a platform plate and lateral actuator enabling two-sided functionality, a transfer belt system with driven rollers for seamless loading and unloading, and a cleaning/disinfecting treatment system to mitigate friction and enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transfer devices (Hoyer Lifts) are used, then patient transfer can be performed, but operator strain and risk of injury increase
Solution Approach 1:
The transfer device enables self-service transfer through the platform and belt system that automatically moves the patient without requiring manual lifting or positioning by operators. The platform extends and retracts autonomously, and the belt provides continuous support during transfer, eliminating the need for operators to physically handle the patient.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated mechanical system. The platform lateral actuator and driven rollers substitute for human physical effort, converting operator-dependent manual transfer into an automated mechanical process that reduces both strain and injury risk.
2Productivity
If traditional transfer devices are used, then patient transfer is possible, but cost and operational complexity increase
Solution Approach 1:
The transfer device is segmented into distinct functional modules: a platform for support, lateral actuators for movement, driven rollers for belt operation, and a treatment system. This segmentation allows each component to perform its specific function efficiently while simplifying maintenance and operation compared to integrated traditional systems.
Solution Approach 2:
The platform serves multiple functions: it supports the patient during transfer, provides a surface for the belt to operate on, and can be extended to both sides for two-sided functionality. The belt system simultaneously provides support and enables movement, reducing the need for separate devices and improving productivity.
3Adaptability or versatility
If traditional transfer devices are used, then basic transfer function is provided, but two-sided functionality is not supported
Solution Approach 1:
The platform is designed with asymmetric extendability, capable of extending to both the left and right sides independently through lateral actuators. This asymmetric design enables two-sided functionality where the platform can extend to either side depending on the transfer direction, providing versatility without requiring manual manipulation for reconfiguration.
4Reliability
If manual handling is used in transfer, then device simplicity is maintained, but operator strain and patient safety increase
Solution Approach 1:
The transfer belt acts as an intermediary between the patient and the platform, providing continuous support and reducing the need for direct manual handling. The belt system mediates the transfer process by distributing the patient's weight and enabling smooth movement, thereby improving patient safety while reducing automation requirements.

AI summary
Disclosed is a transfer device having a device body, a transfer platform including a platform plate, and a platform lateral actuator. The platform lateral actuator is configured to selectively move the platform plate laterally relative to the device body, such that the platform plate can be moved between a plurality of positions including (i) a stowed position in which the platform plate is retracted relative to the device body, (ii) a first extended position in which a first transverse edge of the platform plate is a leading edge that extends outward from a first side of the device body, and (iii) a second extended position in which a second transverse edge of the platform plate is a leading edge that extends outward from a second side of the device body. The transfer device also a treatment system configured to apply a cleaning and/or disinfecting treatment.
