Pivoting Receptacle Locking Arms With Sliding Sleeve Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for collection receptacles often fail to securely prevent access, as they are not easily lockable or are not designed to fit various receptacle sizes, leading to security issues and accessibility concerns.
Innovation Solution
A locking device comprising a frame with pivotable locking arms and a sliding sleeve, which aligns with throughholes to receive a lock, ensuring secure alignment and preventing movement, along with bumpers for a tight friction fit on the receptacle, allowing for secure attachment and lockable configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing locking devices are used on collection receptacles, then the receptacles can be locked to some extent, but they fail to securely prevent access due to inadequate alignment and movement prevention mechanisms
Solution Approach 1:
The locking device is divided into distinct functional components: locking arms for engagement, a locking sleeve for alignment, and throughholes for lock insertion. This segmentation allows each component to perform its specific function effectively, with the locking arms providing the primary locking action and the locking sleeve ensuring precise alignment to prevent movement.
Solution Approach 2:
The locking sleeve acts as an intermediary element between the locking arms and the lock. It slides to partially surround one of the locking arms and aligns the throughholes, serving as a mediator that ensures proper positioning and prevents movement of the locking components relative to each other.
2Reliability
If a secure locking mechanism is implemented, then access prevention is improved, but the device becomes more complex with additional alignment and movement prevention components
Solution Approach 1:
The locking sleeve combines multiple functions into a single component: it aligns the throughholes, surrounds the locking arm for stability, and works in conjunction with the locking arms to prevent movement. This merging reduces the need for separate alignment mechanisms and movement prevention components.
Solution Approach 2:
The locking sleeve partially surrounds one of the locking arms, creating a nested configuration where the sleeve encloses the locking arm. This nesting provides structural support and alignment while maintaining a compact design that does not significantly increase the overall device complexity.
3Volume of moving object
If the locking arms are positioned near one another in the first position, then the structure is compact, but in the second position they must be positioned away from one another requiring more space
Solution Approach 1:
The locking arms are designed to be movable between two positions: a first position where they are near one another for compact storage, and a second position where they are positioned away from one another for locking operation. This dynamic design allows the device to transition between compact and operational states, facilitating easy operation while maintaining a small footprint when not in use.

AI summary
Receptacle locking devices are disclosed. A receptacle locking device having a contact arm and a pivoting feature can be pivoted from a first, unlocked position to a second, locked position, wherein the contact arm prevents opening of the receptacle door when the locking device is in the second, locked position.
