Garbage Container Lid Blocking Mechanism for Unintended Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage container lids are prone to unnecessary actuation when objects, people, or pets pass through the sensing area, leading to unintended opening and odor emission.
Innovation Solution
A garbage container lid with an integrated locking device and opening and closing system, featuring a blocking member that can be manually positioned to prevent interference with the lid's movement path, ensuring the lid remains closed unless intentionally opened, and a timing unit to prevent continuous operation of the driving unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sensing lid is used to automatically open the lid when objects pass through the sensing area, then hands-free operation is achieved, but unnecessary actuation occurs leading to odor emission
Solution Approach 1:
The blocking member is positioned in advance to physically obstruct the lid member's moving path, preventing unintended opening before it can occur. This preliminary mechanical intervention ensures that even if the sensing unit is activated by external objects, the lid member cannot move to an open position without manual intervention to move the blocking member first.
2Ease of operation
If the lid member is freely movable along the moving path, then easy opening is achieved, but accidental opening by external objects occurs
Solution Approach 1:
The blocking member serves as an intermediary element between the sensing unit and the lid member. It mediates the interaction by physically blocking the lid member's path, ensuring that sensing signals do not directly translate to lid opening. The blocking member must be manually moved to allow lid movement, thus filtering out false activation from legitimate user intent.
3Reliability
If a blocking member is added to prevent unintended opening, then reliability is improved, but device complexity increases
Solution Approach 1:
The lid assembly is segmented into functionally independent components: the sensing unit for detection, the driving unit for actuation, the lid member for opening/closing, and the blocking member for control. This segmentation allows each component to perform its specific function with simple structure, while the overall system achieves high reliability through the coordinated interaction of these modular elements.

AI summary
A lid of a garbage container is provided, including: a main body, an opening and closing system and a locking device. The main body includes an input opening. The opening and closing system is disposed on the main body and includes a lid member and a driving unit. The lid member is disposed on the main body and openably covers the input opening. The driving unit drives the lid member to move along a moving path and uncover the input opening. The locking device includes a blocking member disposed on the main body. The blocking member is configured to be externally operable and movable between a locking position and a releasing position. When the blocking member is in the locking position, the blocking member is on the moving path and at least partially interferes with and blocks the lid member.
