Garbage Bin Cover Locking Mechanism for Fixed Open Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional garbage bins with pedal-operated covers require continuous foot action to keep the cover open, making them inconvenient for use in certain situations, as the cover cannot stay open without continuous stepping.
Innovation Solution
A garbage bin with a cover that can be fixedly opened using a locking mechanism involving a support, locking member, and toggle rod, allowing the cover to be locked in an open position with a simple toggle operation, eliminating the need for continuous foot action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pedal mechanism is used to open the cover, then the cover can be opened with foot action, but the user must step on the pedal continually to keep the cover open
Solution Approach 1:
The locking member is designed to automatically engage with the bin shoulder when the support is in the upright position, preliminarily securing the cover in the open state without requiring continuous foot action. The elastic inverted buckle pre-positions the locking member to snap into place automatically.
Solution Approach 2:
The cover opening mechanism serves itself by using the weight and position of the support to automatically engage the locking member with the bin shoulder, eliminating the need for continuous external foot action to maintain the open state.
2Ease of operation
If the cover is opened by stepping on the pedal, then the cover can be opened, but the garbage bin is inconvenient to use when the user cannot keep stepping on the pedal
Solution Approach 1:
The locking member is pre-positioned to automatically engage with the bin shoulder when the support is upright, ensuring the cover remains reliably open without requiring continuous user action. The elastic inverted buckle ensures automatic engagement upon insertion.
Solution Approach 2:
The elastic inverted buckle acts as a disposable, single-use locking element that engages once and maintains the locked state, providing reliable coverage without requiring continuous operation or complex mechanical systems.
3Reliability
If a locking member is added to the support, then the cover can be locked in open position, but the structure becomes more complex
Solution Approach 1:
The locking function is segmented into separate components: the locking member with elastic inverted buckle on the support, and the corresponding recessed part on the bin shoulder. This modular segmentation allows the locking mechanism to be added without redesigning the entire support structure.
Solution Approach 2:
The locking member is nested within the support structure, with the elastic inverted buckle fitting into the recessed part of the bin shoulder. This nesting approach integrates the locking function within the existing structural framework, minimizing additional complexity.

AI summary
A garbage bin with a cover capable of being fixedly opened, comprises a bin body and a movably opened/closed cover mounted on the bin body, wherein a support is arranged at one end of the cover connected to the bin body, a locking member capable of protruding from the support is movably arranged in the support, a bin shoulder is arranged on the bin body, the bin shoulder is provided with a through hole for the support to penetrate through in a matching manner, the locking member is snap-fitted with the bin shoulder, a toggle rod protruding from the support is convexly arranged at one side of the locking member facing the center of the bin body, and a spacing hole for the toggle rod to penetrate through in a matching and receiving manner is arranged at the front side of the support.
