Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional swing gates or turnstiles are used, then passage control is achieved, but it becomes difficult for people with luggage or strollers to pass through

Engineering Contradiction:
ImproveEase of passage for people with luggage or strollersVSAvoidReliability of passage control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The blocking element is divided into multiple segments (first blocking element and second blocking element) that can move independently. This segmentation allows the barrier to adapt its configuration - forming a closed barrier for normal control or an open passage for accessibility needs, resolving the contradiction between control reliability and ease of passage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blocking elements are designed to be dynamically reconfigurable between different positions (blocking position and passage position). The first blocking element can rotate between blocking and passage positions, while the second blocking element can rotate between blocking and retracted positions. This dynamic capability enables the system to switch between strict control mode and accessible passage mode, simultaneously achieving both control reliability and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If complex barrier systems with multiple components are used, then passage control reliability is improved, but device complexity increases

Engineering Contradiction:
ImproveReliability of passage controlVSAvoidComplexity of barrier system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple blocking functions into a unified barrier system where the first and second blocking elements work together. The drive unit integrates the driving mechanism for both elements, and the control unit coordinates their operations. This merging approach achieves reliable passage control through coordinated action of integrated components rather than separate complex systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first blocking element serves multiple functions: it can rotate to the blocking position for normal control, rotate to the passage position for accessibility, and be driven by a universal drive unit. The second blocking element similarly provides both blocking and retraction functions. This multi-functionality reduces the need for separate specialized components, thereby reducing overall device complexity while maintaining control reliability.

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

3Productivity

If automated access control with sensors and motors is implemented, then productivity and access control efficiency are improved, but device complexity and cost increase

Engineering Contradiction:
ImproveAccess control efficiencyVSAvoidComplexity of automated control system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control unit is configured to automatically control the drive unit based on detected passage events. The system can autonomously determine when to move blocking elements based on sensor inputs or control signals, reducing the need for complex manual intervention systems while maintaining high access control efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent employs a drive unit with friction wheels that utilize friction-based driving instead of complex mechanical gear systems. The friction wheels can drive the blocking elements through frictional contact, simplifying the mechanical transmission system while maintaining effective control. This substitution of traditional mechanical gear systems with friction-based driving reduces device complexity while preserving automated control functionality.

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