Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional security devices with multiple separate components are used, then security reliability is improved, but manufacturing cost increases and device complexity increases

Engineering Contradiction:
Improvesecurity reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the tag and sled into a single integrated security device that rotates to lock onto the product neck. This integration reduces the number of separate components while maintaining security functionality through the rotational locking mechanism, thereby reducing manufacturing cost and device complexity without sacrificing reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotational mechanism serves multiple functions: it provides the locking action, ensures proper orientation of the security elements relative to the product, and creates a tamper-resistant configuration. This multi-functionality reduces the need for additional separate components, addressing both complexity and cost concerns

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional latching or locking mechanisms are used, then security is improved, but ease of operation deteriorates due to difficulty in installation and removal

Engineering Contradiction:
ImprovesecurityVSAvoidease of installation and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs a dynamic rotational locking mechanism that transitions from an unlocked to a locked position through rotation. This dynamic action simplifies both installation (simple rotation to lock) and removal (reverse rotation to unlock) compared to static complex latching mechanisms, while maintaining security through the engaged locking position

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces complex mechanical latching systems with a simpler rotational locking system. The rotation mechanism provides secure locking through geometric engagement rather than complex springs and latches, making the device easier to operate while maintaining security

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If security devices with visible components are used, then ease of manufacture is improved, but tamper resistance deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidtamper resistance
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent employs a nested structure where the tag rotates to lock onto the sled, with the security elements positioned within the integrated housing. This nested configuration conceals the security mechanism while maintaining manufacturability, as the components are housed within a unified structure that is straightforward to produce

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The rotational locking mechanism uses asymmetric geometry to provide tamper resistance. The non-symmetric engagement features ensure that the device locks in the correct orientation and cannot be easily manipulated or tampered with, while the overall structure remains manufacturable through standard processes

Inventive Principle:
Principle #4Asymmetry

4Object-affected harmful factors

If security devices occupying significant space are used, then tamper resistance is improved, but productivity deteriorates due to reduced display space

Engineering Contradiction:
Improvetamper resistanceVSAvoiddisplay space efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent transitions from a linear or bulky security device to a compact rotational mechanism that locks onto the product neck in a space-efficient manner. By utilizing the radial dimension around the neck rather than extending linearly, the device provides tamper resistance while occupying minimal display space, allowing more products to be displayed

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
