Solution Overview

Problem

Conventional calendars require complete exposure of pages to view indicia, limiting the ability to see printed material on successive or partially covered pages, which hinders a cohesive and aesthetically pleasing design.

Innovation Solution

The calendar design incorporates removable or omitted portions, such as apertures or perforated sections, allowing aligned portions of other pages to be viewed through these openings, enabling a cohesive and three-dimensional decorative image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If individual pages are completely exposed to view indicia, then all printed material on a page is visible, but the ability to view indicia on successive or partially covered pages is lost

Engineering Contradiction:
Improvevisibility of indiciaVSAvoidpage structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides each page into multiple sections, with certain portions (windows) removed or made transparent to reveal underlying pages. This segmentation allows indicia from multiple pages to be simultaneously visible through the window openings, resolving the contradiction between complete page exposure and partial page visibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a nested structure where multiple calendar pages are stacked, and windows in each page allow viewing of indicia on underlying pages. This nesting arrangement enables simultaneous visibility of multiple pages without completely exposing each individual page, maintaining structural integrity while achieving multi-page visibility.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Loss of information

If apertures or removed portions are created in pages to view underlying pages, then indicia on multiple pages can be viewed simultaneously, but the structural integrity and completeness of individual pages is compromised

Engineering Contradiction:
Improvevisibility of indiciaVSAvoidpage integrity
Core Design Contradiction:
Loss of informationVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating windows or apertures in specific locations on pages where they will align with indicia on underlying pages. This localized modification allows multi-page visibility while preserving the integrity of the majority of each page structure. The windows are strategically placed to maintain both structural stability and visual coherence.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses the window openings as intermediaries that allow light and visual information to pass through from underlying pages to the viewer. These window apertures act as mediators between the indicia on different pages, enabling simultaneous visibility without compromising the physical structure of the pages themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Shape

If pages are designed with aligned windows or apertures to view multiple pages, then a cohesive three-dimensional decorative image is created, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvedecorative designVSAvoidpage production
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent employs preliminary action by pre-aligning and pre-positioning windows or apertures on each page during the manufacturing process. The pages are designed with predetermined window locations that will align when pages are stacked, allowing for the creation of cohesive three-dimensional decorative images. This preliminary positioning simplifies the overall manufacturing process by establishing alignment requirements upfront rather than requiring complex post-assembly adjustments.

Inventive Principle:
Principle #10Preliminary action

AI summary

A calendar has one or more individual pages of the calendar that include portions of the pages that are omitted, removed or removable in order to enable aligned portions of other pages of the calendar to be viewed through the removed portions. The removed portions can be formed as apertures in the page and/or as removed portions of one or more edges of the page, among others to allow the stacked pages to form a coordinated, and optionally customizable, decorative appearance for the calendar.
