Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Lamp post columns in public spaces often serve as a surface for people to place trash, attracting birds and animals and causing litter spread, which is unsightly and costly to clean up.

Innovation Solution

A lamp post column cap system with a sloped cover extension and drainage features to prevent trash placement and divert water, featuring a column cap with an angled cover extension, drainage ports, and a column sleeve to secure over the lamp post, made from durable plastic with UV inhibitors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a flat top surface is provided on the lamp post column, then it provides a stable surface for placing items, but it allows trash and items to be placed on the column

Engineering Contradiction:

Improvesurface for placing itemsVSAvoidtrash accumulation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies a sloped surface design instead of a flat top surface. The cover extension creates an inclined plane that angles downward from the column top, causing placed items to naturally slide off rather than remain stationary. This curved/sloped geometry transforms the horizontal placing surface into a self-cleaning inclined surface.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent converts the harmful effect of items being placed on the column into a beneficial self-cleaning mechanism. By creating a sloped surface, any item placed on the column automatically slides off due to gravity, transforming the problem of trash accumulation into a automatic cleaning system where the weight and placement of items themselves cause their removal.

Inventive Principle:

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

2Object-affected harmful factors

If a sloped cover extension is added to prevent trash placement, then trash accumulation is reduced, but the device complexity increases

Engineering Contradiction:

Improvetrash accumulationVSAvoidcolumn cap structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single integrated column cap assembly. The cover extension, drainage system, and protective collar are merged into one unified component that fits over the column. This integration reduces the number of separate parts while achieving trash prevention, water drainage, and structural protection simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The column cap assembly serves multiple functions: the sloped cover extension prevents trash accumulation, the drainage ports and channels manage water runoff, the collar protects the column top, and the overall structure provides a aesthetic finish. This multi-functional design achieves several goals with a single device rather than multiple separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If drainage ports are added to divert water, then water collection around the lamp post is prevented, but the manufacturing complexity increases

Engineering Contradiction:

Improvewater collectionVSAvoidcolumn cap production

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent incorporates drainage ports (openings) in the column cap that allow water to pass through. The material is designed with integrated hollow channels and openings that enable water permeation while maintaining structural integrity. This porous/drainage design allows water to drain through the cap rather than collect around the lamp post base.

Inventive Principle:

Principle #31Porous materials

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

Effectively prevents trash from being placed on the lamp post column and directs water away, maintaining cleanliness and reducing maintenance costs by deterring litter accumulation.

Implementation Method 1

A cover extension extends at an extension angle from the post flange down towards the base flange or base of the column cap

Methodology Applied

Scientific EffectGravity: Gravitation

Implementation Method 2

The column cap may have drainage for water to drain out from the interior of the column cap to prevent rusting of the lamp post

Methodology Applied

Scientific EffectGravity-driven drainage: Gravitation

AI summary

A lamp post column cover is configured for placement around a lamp post to produce a sloped cover extension to prevent trash from being placed on the lamp post column. The lamp post column cover has a post opening around the top of the lamp post column cover and configured around the lamp post a height above the top of the lamp post column. A post opening flange extends vertically around the post opening and is coupled with the cover extension that extends at an extension angle down towards the column flange or base of the lamp post column cover. A plurality of drainage ports are configured along the base of the lamp post column cover and have a drainage port flange extending over the drainage port. The drainage port flange may extend out from the cover extension or from the drainage step of the lamp post column cover.
