Ambidextrous Foot-Pedal Bin Lid Linkage for Controlled Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage bin lid opening systems are often flimsy, require significant force, fail to lift lids fully, slam shut quickly, or allow lids to pivot too far back, leading to hygiene issues, physical strain, and ineffective pest and odor control.
Innovation Solution
A foot-operated lid opening system with a stirrup and actuating straps connected to lifting devices featuring a bracket, ball joint, torsion spring, and lifting arm, allowing for ambidextrous operation and controlled lid movement, ensuring easy opening and closing without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foot pedal is used to open the lid, then hands-free operation is achieved, but the pedal becomes flimsy and requires significant force for heavy lids
Solution Approach 1:
The patent employs a counterweight mechanism where a weight is suspended on the opposite side of the lid hinge from the foot pedal. This counterweight offsets the weight of the lid, reducing the force required by the foot pedal to lift the lid. The balancing effect allows a lighter-footed pedal design while maintaining adequate lifting capability for heavy lids.
2Extent of automation
If a spring-loaded mechanism is used for automatic closing, then automatic closure is achieved, but the lid slams shut quickly causing hygiene and control issues
Solution Approach 1:
The patent incorporates a damping mechanism or cushioning element in the closing path of the lid. This could be a rubber bumper, foam pad, or viscous damper positioned near the closed position that absorbs the kinetic energy of the closing lid, reducing the impact force and preventing slamming while maintaining automatic closure functionality.
3Ease of operation
If the lid is allowed to pivot freely, then easy opening is achieved, but the lid pivots too far back causing hygiene and retrieval issues
Solution Approach 1:
The patent implements a mechanical stop or limiter in the hinge mechanism that prevents the lid from rotating beyond a predetermined angle. This stop could be a physical block, a cam mechanism, or a keyed hinge that mechanically restricts the maximum rotation, ensuring the lid does not pivot too far back while still allowing sufficient opening for trash disposal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a robust, hygienic, and efficient method for opening and closing garbage bin lids, reducing physical strain and maintaining effective pest and odor containment.
Implementation Method 1
A torsion spring is mounted about the central pillar. It is operatively connected between the spring attachment plate and the lifting arm to bias the lifting arm towards a lid-closed position.
Implementation Method 2
A lifting arm assembly, comprising a lifting arm and a connected ball joint, is also part of the lifting device.

AI summary
A foot-operated lid opening system for a bin, utilizing a stirrup connected by at least one actuating strap to at least one lifting device. Each lifting device features a bracket with a slitted hemisphere and a substantially fixed spring attachment plate; this plate includes a central pillar and at least one cavity. A lifting arm assembly, comprising a lifting arm with an integral ball joint and stub, has its stub passing through the slit to engage the cavity. A torsion spring, mounted on the pillar, biases the lifting arm towards a lid-closed position. Foot actuation pulls the strap, pivoting the lifting arm via the stub's engagement to open the lid with a lifting pin. A key aspect is its ambidextrous design, enabling left or right-side bin mounting. This is achieved through a rotatable stub, a flippable lifting arm with a double-sided pin, and typically multiple cavities on the spring attachment plate.
