Garbage Container Lid Blocking Mechanism for Unwanted Actuation
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 member, then convenience is improved, but the lid member is easily actuated by objects, people or pets passing through the sensing area, causing unnecessary opening
Solution Approach 1:
The blocking member is positioned in advance in the locking position to preemptively prevent the lid member from moving. When an object passes through the sensing area, the blocking member is already in place to block the lid member's movement path, thereby preventing unwanted actuation while maintaining the automatic opening function when needed
Solution Approach 2:
The blocking member acts as an intermediary element between the sensing unit and the lid member. It receives the actuation signal from the sensing unit but mediates the action by blocking the lid member's movement path, preventing direct translation of sensing signals into lid movement unless the blocking member is moved to the releasing position
2Reliability
If the blocking member is in the locking position to prevent unwanted opening, then reliability is improved, but the lid member cannot be opened even when intended
Solution Approach 1:
The blocking member is designed to be movable between the locking position and the releasing position. This dynamic positioning allows the system to adapt between two states: blocking the lid member to prevent unwanted opening, and removing the block to allow intentional opening. The user can manually move the blocking member to the releasing position when intentional opening is needed

AI summary
A lid of a garbage container is provided, including: a main body (1), an opening and closing system (2) and a locking device (27). The main body (1) includes an input opening (11). The opening and closing system (2) is disposed on the main body (1) and includes a lid member (21) and a driving unit (24). The lid member (21) is disposed on the main body (1) and openably covers the input opening (11). The driving unit (24) drives the lid member (21) to move along a moving path (4) and uncover the input opening (11). The locking device (27) includes a blocking member (3) disposed on the main body (1). The blocking member (3) is configured to be externally operable and movable between a locking position and a releasing position. When the blocking member (3) is in the locking position, the blocking member (3) is on the moving path (4) and at least partially interferes with and blocks the lid member (21).
