Vehicle Lift Indicator System for Locking Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lifts lack a reliable indicator system to quickly determine if the load is being borne by the locking mechanism, leading to potential safety hazards due to uncertainty about the lift's locked position.
Innovation Solution
An indicator system incorporating a pressure sensor and visual indicators, such as lights or analog gauges, that monitor hydraulic fluid pressure to visually signal whether the lift is in a locked or unlocked state, ensuring users can verify the load-bearing mechanism's engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to prevent sudden dropping, then safety is improved, but the complexity of the device increases
Solution Approach 1:
The patent introduces an indicator system as an intermediary component that mediates between the locking mechanism and the user. This indicator system includes visual indicators (such as lights or flags) that clearly show whether the locking mechanism is engaged, allowing users to verify the locked position without adding complex control or monitoring systems. The indicator acts as a simple mediator that translates the mechanical state into visible information.
2Loss of information
If an indicator system is added to show locked position, then information availability is improved, but the device complexity increases
Solution Approach 1:
The indicator system is designed to automatically indicate the locked position without requiring external power sources, control systems, or user intervention. The visual indicators are mechanically coupled to the locking mechanism itself, so they self-activate based on the mechanical state. This self-service approach provides information about the locked position while minimizing added complexity.
3Reliability
If the locking mechanism engages only after slight lowering, then the locking reliability is improved, but the operational time increases
Solution Approach 1:
The system performs a preliminary action of slight lowering after the initial lifting to ensure the locking mechanism fully engages. This preliminary lowering action, while small, is critical for achieving reliable locking. The indicator system helps users recognize when this preliminary action has been completed and the lock is engaged, allowing them to proceed with confidence.

AI summary
An apparatus comprises a frame, a vehicle engagement assembly, a lift actuation assembly, a locking assembly, and an indicator system. The vehicle engagement assembly is designed to vertically lift a vehicle. The frame comprises at least one slot to provide a predetermined path for the vehicle engagement assembly. The lift assembly provides the force required to lift the vehicle while the locking assembly stabilizes the vehicles without further force required by the lift assembly. The indicator system determines whether the locking assembly or the lift assembly is predominantly keeping the vehicle lifted.
