Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional used car buyers guides are double-sided, requiring sellers to securely affix them to vehicle windows, but existing methods lack a resilient and user-friendly solution for attachment, especially considering the need for variable information to be printed or written by the seller.

Innovation Solution

A printable cling-type document comprising a synthetic paper layer, a cling layer with static properties, and a protective backing layer, allowing preprinted information on one side and user-printable/writable areas on the other, with a cling layer that can adhere to vehicle windows without adhesives, enabling easy attachment and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional plain paper stickers are used for buyers guides, then printing and writing on the paper is easy, but the paper lacks water resistance and temperature resistance when exposed to vehicle window conditions

Engineering Contradiction:

Improvewater resistance and temperature resistanceVSAvoidprinting and writing capability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent uses composite materials by combining synthetic paper with plasticizer and coating layers to achieve both durability (water and temperature resistance) and printability. The synthetic paper base provides structural integrity and environmental resistance, while the coating layer enables inkjet printing capability.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent modifies the physical and chemical parameters of the paper through adding plasticizer and applying coatings. These parameter changes transform ordinary paper into a material that maintains flexibility and printability while gaining water resistance and temperature resistance properties.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If adhesive stickers are used to secure the buyers guide to the vehicle window, then the guide stays in place securely, but removal and repositioning become difficult and may damage the window

Engineering Contradiction:

Improvesecure attachmentVSAvoidremoval and repositioning

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical adhesive bonding system with an electrostatic cling system. The charged cling layer adheres to the conductive vehicle window through electrostatic attraction without using adhesives, allowing easy removal and repositioning while maintaining secure attachment during use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The conductive cling layer acts as an intermediary between the buyers guide and the vehicle window. It provides the attachment function through electrostatic cling while allowing the guide to be easily removed and repositioned, eliminating the need for adhesive materials.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the buyers guide is made as a single-layer paper, then it is simple and inexpensive to produce, but it cannot provide both printability and protective cling functionality

Engineering Contradiction:

Improvecombined printability and cling functionalityVSAvoidmulti-layer structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated structure by combining the synthetic paper layer, cling layer with static electricity, and protective backing layer into one multi-functional component that provides printability, attachment, and protection simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the buyers guide into distinct functional layers: a synthetic paper layer for printing and writing, a cling layer with static electricity for attachment to the window, and a protective backing layer. Each layer performs a specific function while working together as an integrated system.

Inventive Principle:

Principle #1Segmentation
