Solution Overview

Problem

Conventional multi-panel display boards face issues with side panels not staying in obtuse angular orientations without support, misplacement of detachable header panels, and aesthetic concerns from perforation residue, especially when used on carpeted surfaces or without additional support structures like footers and braces.

Innovation Solution

A multi-panel display board design with a permanently attached header panel and single wallboard construction, where the non-mottled linerboard is slit to create creases in the mottled linerboard, allowing the board to stand stably with side panels at obtuse angles without additional support, using corrugated cardboard or similar materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If side panels are made pivotable about panel creases to achieve obtuse angular orientations, then the board can be deployed in spread-apart configurations, but the side panels cannot remain stable in obtuse angular orientations without additional support structures

Engineering Contradiction:

Improvepanel orientation capabilityVSAvoidpanel position stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The panel creases are pre-formed by slitting the non-mottled linerboard in specific patterns that create predetermined fold lines. This preliminary action during manufacturing ensures that when the side panels are pivoted to obtuse angular orientations, the slitted crease lines provide structural guidance and stability to maintain the deployed configuration without requiring additional support structures.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If a detachable header panel is used to secure side panels at desired orientations, then the side panels can be held at obtuse angles, but the header panel may become misplaced when not in use

Engineering Contradiction:

Improvepanel position stabilityVSAvoidheader panel usability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The header panel is permanently attached to the multi-panel display board through integral construction, merging the header panel with the side panels and central panel into a single unified structure. This eliminates the need for detachable connections while ensuring the header panel remains in its proper position, preventing misplacement issues.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If traditional male creasing profiles are used on recycled board, then creasing can be achieved, but rolling scores and manufacturer's gap variation occur leading to crooked creased lines

Engineering Contradiction:

Improvecreasing capabilityVSAvoidcrease line straightness

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The invention changes the creasing method from traditional male profiles that force board stretching to a slitting approach where the non-mottled linerboard is cut or slit to create crease lines. This parameter change in the creasing mechanism eliminates rolling scores and manufacturer's gap variation, producing straight, clean creased lines even when working with recycled board materials.

4Object-affected harmful factors

If side panels are made from lightweight corrugated board with C flutes for cushioning, then better cushioning properties are achieved, but the board lacks rigidity to maintain obtuse angular orientations without support

Engineering Contradiction:

Improvecushioning protectionVSAvoidstructural rigidity

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The invention uses composite construction with a corrugated medium (C flutes for cushioning) sandwiched between two linerboards (mottled and non-mottled). The slitting of the non-mottled linerboard creates rigid crease lines that provide structural stability, while the corrugated medium maintains cushioning properties. This composite structure achieves both cushioning and rigidity simultaneously.

AI summary

A multi-panel display project board with a center panel between two side panels and with a header panel movable between a fold-in position and a fold-out position. Each panel has a medium sandwiched between two linerboards. Creases between the panels are formed by slitting linerboard beneath the creases. The side panels may be spread apart to define obtuse angles relative to the central panel and yet retain their position on their own when erected on a flat surface. The header panel has a long segment separated from two shorter segments by segment creases. When the header panel is in the fold-in position after pivoting from a fully folded orientation about panel creases, the shorter segments define respective obtuse angles with the long segment. In the fold-out position after pivoting the header panel about additional creases, the shorter segments define respective reflex angles instead.
