Solution Overview

Problem

Existing litter bins on tables are impractical, often falling or spilling contents when tables are moved or subjected to strong winds, lacking a secure and convenient waste disposal solution.

Innovation Solution

A litter bin designed with a hollow body fastened to the table via removable fastening means, featuring a base with an operable lid for secure waste disposal, preventing spillage and easy replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a litter bin is placed on top of the table, then waste disposal is available at the table, but the litter bin can fall or be blown over by wind, spilling contents on the floor

Engineering Contradiction:

Improvewaste disposal availabilityVSAvoidlitter bin stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The litter bin is merged with the table structure by integrating it into the table's base or frame. This combination ensures the litter bin moves with the table and cannot fall or be blown over independently, while still providing waste disposal functionality at the table surface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The litter bin is nested within the table structure, either inside the table base or within a dedicated compartment. This nesting approach allows the litter bin to be securely housed within the table's overall structure, preventing it from falling while maintaining accessibility for waste disposal.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If a litter bin is placed on top of the table, then waste disposal is available at the table, but the litter bin spills contents when moved to put tables together

Engineering Contradiction:

Improvewaste disposal availabilityVSAvoidcontent spillage

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The litter bin is combined with the table structure so that when tables are moved or joined together, the litter bin moves as an integrated unit with the table. This prevents the litter bin from falling or spilling contents during table reconfiguration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The litter bin is pre-secured to the table structure through fastening mechanisms or structural integration. This preliminary securing action ensures that the litter bin remains stable and prevents content spillage before any table movement or reconfiguration occurs.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a litter bin is fastened securely to the table, then stability is improved, but the litter bin becomes difficult to replace when damaged

Engineering Contradiction:

Improvelitter bin stabilityVSAvoidlitter bin replacement

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The litter bin is designed as a separate, modular component that can be easily detached from the table structure. This segmentation allows the litter bin to be securely fastened during use for stability, while enabling quick removal and replacement when damaged or full, without requiring complex disassembly procedures.

Inventive Principle:

Principle #1Segmentation
