Solution Overview

Problem

Conventional cushioned garbage containers are inconvenient and time-consuming to maintain due to the frequent need for replacing the cushion element, which requires disassembling other components.

Innovation Solution

A cushioned garbage container design featuring a linkage mechanism with a detachable cushion element, allowing for direct replacement without disassembling other elements, utilizing a stamping member, propping rod, and driving member to facilitate easy access and engagement of the cushion element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cushion element is disposed inside the garbage container integrated with other components, then the cushion function is achieved, but the replacement of cushion element becomes difficult and time-consuming

Engineering Contradiction:

Improvecushion functionVSAvoidcushion element replacement

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The cushion element is designed as a separate, independent component that can be removed and replaced without disassembling other parts of the garbage container. The receiving space is specifically designed to accommodate and detachably hold the cushion element, allowing users to replace it easily when worn out.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cushion element is extracted as a standalone replaceable component from the integrated structure. It can be taken out from the receiving space independently, and the receiving space is designed to allow easy access and removal of the cushion element without affecting other components of the garbage container.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of repair

If the cushion element is made detachable for easy replacement, then the ease of repair is improved, but the structural complexity increases

Engineering Contradiction:

Improvecushion element replacementVSAvoidlinkage mechanism structure

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The linkage mechanism is segmented into distinct functional components: the stamping member for actuation, the propping rod for support and motion transmission, and the driving member for converting stamping motion into cover opening. This segmentation allows the cushion element to be independently replaceable while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The propping rod serves multiple functions: it supports the cover body, transmits motion from the stamping member to the driving member, and provides a mounting structure for the cushion element. This multi-functionality reduces the need for additional components, thereby limiting the increase in structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If the cover body drops quickly after stamping, then the operation speed is improved, but the noise increases and cushion function is reduced

Engineering Contradiction:

Improvecover body movement speedVSAvoidnoise

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The cushion element is pre-installed in the receiving space to cushion the cover body before it completes its downward movement. This beforehand cushioning reduces the impact noise when the cover body drops and provides a controlled deceleration, maintaining operational speed while reducing harmful noise.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The potential harmful effect of the cover body dropping quickly is converted into a benefit by using the stamping action itself to compress the cushion element, which then provides controlled resistance to slow down the cover body. The initial quick drop is transformed into a beneficial cushioned closing action that reduces noise and wear.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A cushioned garbage container includes a main body, a linkage mechanism and a cushion element. The main body has a barrel body and a cover body, the barrel body has a first block having a receiving portion and a second block, and the receiving portion has a receiving space and a positioning portion located in the receiving space. The linkage mechanism is disposed on the barrel body and is comovable with the cover body, the linkage mechanism has a stamping member, a propping rod connected to the stamping member, and a driving member disposed on the propping rod and located in the receiving space. The cushion element is detachably disposed in the receiving space, has a fixed portion having a positioning assembly and a movable portion, the positioning assembly is restrictedly engaged with the positioning portion, and the movable portion is engaged with the driving member.
