Reversible Flap Pedal Bin Mechanism for Handedness Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary hygiene bins often require left or right-handed configurations, which can be inconvenient for applications where the pedal must face forward, and existing designs do not easily accommodate reversible flap orientations without modifying the pedal or actuating mechanism.
Innovation Solution
A pedal bin with a pivotally mounted flap that can be located in multiple positions to open in different directions, allowing the flap to face either side while the pedal remains forward-facing, utilizing a mechanism that operates the flap in either position without adjustments, and incorporating a platform for hiding contents and accommodating various bag sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flap is fixed in a single position to open in one direction, then the bin structure is simple, but the bin cannot accommodate different handedness requirements (left or right-handed configurations)
Solution Approach 1:
The flap is designed with dual functionality by providing two distinct positions: a first position for opening in a first direction (e.g., right-handed configuration) and a second position for opening in a second direction (e.g., left-handed configuration). The actuating member is configured to operate the flap in either position, allowing a single bin design to serve multiple handedness requirements without requiring separate left-handed and right-handed versions.
2Adaptability or versatility
If the flap is made reversible to open in multiple directions, then the bin can accommodate different orientations, but the mechanism complexity increases
Solution Approach 1:
The bin body exhibits asymmetric features with a front wall, rear wall, and side walls, allowing the flap to pivot between asymmetric positions. The actuating member is positioned to engage the flap at locations that enable opening in opposite directions while maintaining the pedal's forward-facing orientation. This asymmetric design allows the same mechanism to achieve reversible functionality without requiring symmetric modifications.
3Adaptability or versatility
If the pedal is repositioned to accommodate different flap orientations, then the bin can be handed, but the pedal no longer faces forwards consistently
Solution Approach 1:
The opening mechanism is segmented into independent components: the pedal remains fixed in its forward-facing position on the front wall, while the flap and actuating member form a separate movable segment. The actuating member connects the pedal's linear motion to the flap's rotational motion, allowing the flap to be positioned in either the first or second position without requiring the pedal to change its orientation. This segmentation maintains consistent pedal operation while enabling handedness flexibility.

AI summary
A pedal bin includes a container, a pedal and a pivotably mounted flap. The flap is locatable in a first position to facilitate opening of the flap in a first direction relative to the container. The flap is also locatable in a second position to facilitate opening of the flap in a second direction relative to the container. In either position, the pedal is operable to open the flap.
