Induction actuated container

What is this patent about?

’655 is related to the field of automated waste and storage management, specifically focusing on hands-free containers equipped with proximity-based opening mechanisms. The technology addresses the hygiene and convenience issues inherent in manual lids, particularly in medical or waste disposal environments where physical contact with a container can lead to cross-contamination or the spread of infection.

The underlying idea behind ’655 is the integration of a non-contact proximity sensor with a motorized mechanical linkage to automate the lid’s movement. By converting a detected physical presence into a timed electrical command, the system eliminates the need for foot pedals or manual lifting, using a driven operating member to translate motor or electromagnetic force into the vertical or rotational displacement of the cover.

The claims of ’655 focus on the mechanical and electrical coordination between an induction sensor, an actuating controller, and a drive assembly. The system is defined by a transmissive connection where a driving member moves an operating rod—such as a crown bar—to physically shift the lid between open and closed states based on signals processed by a monostable trigger circuit.

In practice, the invention utilizes various sensing modalities, such as inductive oscillators, microwave probes, or infrared pairs, to detect an approaching user. When a person enters the detection zone, the controller triggers a timed interval that energizes the drive unit. A key implementation detail involves a limit means using upper and lower travel switches to precisely define the lid's range of motion, ensuring the motor stops once the cover reaches its fully open or closed position.

This approach differentiates itself from prior art by replacing manual or purely mechanical foot-pedal systems with an automated, circuit-driven response. Unlike basic spring-loaded lids, this design uses a monostable trigger to maintain the open state for a specific duration before automatically initiating the closing sequence. This ensures a consistent, hygienic user experience while protecting the internal components within a dual-layered body structure consisting of an outer housing and a removable inner barrel.
