Solution Overview

Problem

Replacing posters in high locations, such as windows, is cumbersome and inefficient, often requiring ladders and multiple steps.

Innovation Solution

A frame tool and poster tool system that allows for poster replacement without a ladder, utilizing a head with angled recesses and pole attachments to manipulate frame panels from a distance, enabling single-user operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a ladder is used to replace the poster display from a high location, then the poster can be replaced, but the process becomes cumbersome and inefficient

Engineering Contradiction:

Improveposter replacement efficiencyVSAvoidoperation complexity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

A pole attachment with a head assembly serves as an intermediary tool, allowing the user to manipulate the frame panels from ground level without needing to physically access the high-mounted poster display. The pole transmits force and motion from the user's hands at ground level to the frame panels at height, eliminating the need for a ladder while maintaining operational capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the poster display is mounted high on a building window, then it is visible for advertising, but replacing the poster becomes difficult

Engineering Contradiction:

Improvedisplay location flexibilityVSAvoidposter replacement difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The frame is divided into separable panels that can be independently manipulated. The head assembly includes features like a fulcrum and panel engagement elements that can interact with individual frame panels, allowing each panel to be opened, closed, or repositioned separately. This segmentation enables poster replacement by working with one panel at a time from ground level.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame panels are designed to be movable between open and closed positions, and the head assembly provides dynamic interaction through features like the fulcrum that can pivot and engage with panels at different stages of movement. This dynamic design allows the panels to be manipulated from a distance, enabling poster replacement without fixed access points.

Inventive Principle:

Principle #15Dynamics

3Productivity

If current methods are used to replace posters in high locations, then the task can be completed, but multiple steps and equipment are required

Engineering Contradiction:

Improvereplacement speedVSAvoidequipment requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The pole attachment, head assembly, fulcrum, and panel manipulation features are merged into a single integrated tool system. This combined device performs multiple functions (reaching, lifting, opening, closing, securing) that would otherwise require separate tools and equipment, reducing the overall system complexity while improving replacement speed.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A frame tool for placing a poster in a poster display or removing the poster from the poster display includes a head having a first major panel that opposes a second major panel. The first major panel and the second major panel are connected to a top end that includes an angled recess. The first major panel may include a concave surface connected to the top end. The second major panel may include a fulcrum disposed away from the top end.
