Solution Overview

Problem

Current playing cards and accessories fail to adequately ensure the privacy of card information during and after gameplay, particularly in multiplayer settings, making it difficult for players to conceal their cards from other players.

Innovation Solution

The development of card covers and kits that utilize static charge, magnets, velcro, or adhesives to secure to playing cards, featuring display windows and obscuring portions with privacy filters, allowing players to selectively reveal or conceal card information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional playing cards are used without privacy covers, then the device complexity is low and ease of operation is high, but card information privacy cannot be ensured and information leakage occurs to nearby players

Engineering Contradiction:

Improvecard information privacyVSAvoidprivacy cover structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The card cover is divided into multiple functional segments: a transparent display window region for viewing card information and an obscuring portion with privacy filter for blocking views from side angles. This segmentation allows the single card cover to simultaneously provide both visibility for the player and privacy protection from others, resolving the contradiction between information access and information protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the card cover have different optical properties: the display window region is transparent to allow clear viewing of card information by the player, while the obscuring portion contains a privacy filter that creates directional visibility. This local differentiation of material properties enables the cover to provide both open access and restricted access functions within a single component.

Inventive Principle:

Principle #3Local quality

2Loss of information

If privacy filters are added to card covers, then card information privacy is improved, but the ease of operation deteriorates due to reduced visibility through filtered areas

Engineering Contradiction:

Improvecard information privacyVSAvoidcard information visibility

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

3Reliability

If card covers with attachment mechanisms are used, then reliability of privacy protection is improved, but device complexity increases due to additional attachment components

Engineering Contradiction:

Improveprivacy protection reliabilityVSAvoidattachment mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The card cover incorporates self-adhesive mechanisms that enable the cover to attach to the playing card automatically without requiring separate attachment tools or complex assembly procedures. The adhesive property is built into the card cover itself, allowing players to simply place the cover on the card for immediate secure attachment and privacy protection, eliminating the need for additional attachment devices.

Inventive Principle:

Principle #25Self-service
