Adjustable Receptacle Lid Fastener With Automatic Dump Release

Solution Overview

Problem

Standardized waste receptacles often have flimsy lids that are easily dislodged by weather or wildlife, leading to garbage spillage and environmental pollution.

Innovation Solution

A lid fastener system comprising a strap and connection plate that secures the lid to the receptacle, featuring a positionally adjustable strap with a buckle and a releasable attachment mechanism, ensuring the lid remains closed even under adverse conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a flimsy lid is used on standardized waste receptacles, then the receptacle is simple and inexpensive, but the lid is easily dislodged by weather or wildlife

Engineering Contradiction:

Improvesimplicity and low cost of receptacleVSAvoidlid security against dislodgement

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The fastening system is divided into separate functional components: an anchor plate attached to the lid, a connection plate attached to the receptacle body, and a strap connecting them. This segmentation allows each component to be optimized independently while maintaining overall simplicity and effectiveness in preventing lid dislodgement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The strap acts as an intermediary element between the anchor plate on the lid and the connection plate on the receptacle body. This intermediary component transfers and distributes the securing force, enabling reliable lid attachment without requiring complex integrated structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a secure fastening system is added to prevent lid dislodgement, then lid security is improved, but the device complexity increases

Engineering Contradiction:

Improvelid security against dislodgementVSAvoidnumber of fastening components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fastening system is divided into separate functional components: an anchor plate attached to the lid, a connection plate attached to the receptacle body, and a strap connecting them. This segmentation allows each component to be optimized independently while maintaining overall simplicity and effectiveness in preventing lid dislodgement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The strap is designed with adjustable length capability, allowing the fastening system to adapt to different receptacle sizes and configurations. This dynamic adjustment feature maintains simplicity by eliminating the need for multiple fixed-length straps or complex sizing mechanisms.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the strap length is fixed, then the fastening system is simple, but it cannot accommodate different receptacle sizes

Engineering Contradiction:

Improvecompatibility with different receptacle sizesVSAvoidadjustability mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The strap is designed with adjustable length capability, allowing the fastening system to adapt to different receptacle sizes and configurations. This dynamic adjustment feature maintains simplicity by eliminating the need for multiple fixed-length straps or complex sizing mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The strap length parameter can be changed or adjusted to accommodate different receptacle dimensions. This parameter change capability provides versatility across different receptacle sizes while maintaining a simple single-strap design rather than requiring multiple specialized components.

Inventive Principle:

Principle #35Parameter changes
