Problem

Current motorized transport structures in the healthcare field lack simplicity of use and flexibility, requiring improvements in comfort and industrial production costs.

Innovation Solution

A motorized transport structure with a support frame, main wheel groups that can be configured into free, half-locking, and locking positions, and an auxiliary wheel group, controlled by a control unit and actuator means, including a control device for enabling signals to optimize movement and prevent undesired movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If motorized transport structures include multiple wheel groups with complex control mechanisms for positioning and movement control, then maneuverability and safety are improved, but device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoidcontrol mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control unit automatically determines the operating position of main wheel groups using sensor means and autonomously commands actuator means to adjust wheel positions. This self-service approach eliminates the need for complex manual control mechanisms while maintaining safety and maneuverability through automated position detection and adjustment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Sensor means detect the operating position of main wheel groups and provide feedback signals to the control unit. The control unit processes this feedback and automatically adjusts wheel positions via actuator means, creating a closed-loop control system that ensures safety without requiring complex manual intervention mechanisms.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If motorized transport structures include automated control units with sensor means for determining wheel positions and commanding actuators, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvesimplicity of useVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control unit automatically determines the operating position of main wheel groups using sensor means and autonomously commands actuator means to adjust wheel positions. This self-service approach eliminates the need for complex manual control mechanisms while maintaining safety and maneuverability through automated position detection and adjustment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical control operations are replaced by an automated control unit that uses sensor means to detect wheel positions and electric actuator means to adjust them. This substitution of mechanical control with automated electro-mechanical systems simplifies user operation while managing complexity through integration.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If main wheel groups are designed with multiple positions (free, half-locking, locking) for optimal maneuverability, then ease of operation is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidindustrial production complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The main wheel groups are designed with dynamic positioning capabilities, allowing automatic transition between free, half-locking, and locking positions based on operational requirements. This dynamic design enables optimal maneuverability while the automated control system manages the complexity of position transitions, making the system adaptable rather than statically complex.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The actuator means serve multiple functions: they can lock wheels in place, unlock them for free movement, and position them in intermediate half-locking states. This multi-functionality consolidates what would otherwise require separate mechanisms for each position, simplifying manufacturing while maintaining operational flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
