Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If friction-based gripping is used, then the device can hold objects, but the gripping reliability is insufficient and may cause damage to the object

Engineering Contradiction:

Improvegripping reliabilityVSAvoiddamage to object

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional friction-based mechanical gripping system with a ratchet mechanism that uses mechanical interlocking. The ratchet teeth engage with the strap to create a positive lock, eliminating reliance on friction alone. This substitution provides reliable securing without the harmful sliding and crushing forces that damage objects in friction-based systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The gripping force is divided into discrete engagement points through the ratchet teeth. Instead of continuous friction pressure, the strap engages at specific tooth interfaces, distributing the securing force across multiple discrete points. This segmentation prevents concentrated stress that could damage the held object while maintaining secure retention.

Inventive Principle:

Principle #1Segmentation

2Reliability

If friction-based gripping is used, then the device structure is simple, but the locking capability is insufficient

Engineering Contradiction:

Improvelocking capabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the gripping function with a ratchet locking mechanism into a single integrated system. The strap serves dual purposes: it provides the gripping force and simultaneously engages with the ratchet teeth to create the lock. This combination achieves reliable locking capability without requiring separate complex locking components, thus limiting the increase in device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The ratchet mechanism is designed to be self-locking through the inherent geometry of the ratchet teeth and pawl. Once engaged, the mechanism automatically maintains the locked state without requiring active control or additional power. The strap itself serves as both the gripping element and the locking medium, eliminating the need for separate actuation systems and reducing overall device complexity.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If traditional gripping devices are used, then the device structure is simple, but dual functionality for mounting is lacking

Engineering Contradiction:

Improvedual functionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the gripping device with universal mounting capabilities by incorporating standardized mounting interfaces that can attach to various surfaces and objects. The same ratchet mechanism that provides gripping security can also serve as a mounting system when the strap is configured appropriately. This multi-functionality is achieved by making the core mechanism adaptable to different applications without requiring entirely separate systems, thus limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
