Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional opening mechanisms with multiple movable elements are used, then the locking function is achieved, but wear and tear occurs leading to reliability deterioration and jamming

Engineering Contradiction:
Improveopening mechanism reliabilityVSAvoidnumber of movable elements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential locking function from complex multi-element mechanisms, using only three critical elements (locking element, blocking element, spring element) to achieve the same security function with minimal components, thereby eliminating wear from unnecessary moving parts

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces traditional complex mechanical opening mechanisms with a biometric authentication system (fingerprint sensor, microcontroller) that electronically controls a simple motor-driven blocking mechanism, substituting mechanical complexity with electronic control

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

2Adaptability or versatility

If traditional opening mechanisms with multiple elements are used, then the locking function is achieved, but the device size becomes large preventing use on personal items

Engineering Contradiction:
Improveapplicability to personal itemsVSAvoidopening mechanism size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent extracts only the essential components needed for locking functionality, eliminating extraneous elements, resulting in a compact mechanism small enough to be integrated into personal items like laptops and diaries

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the locking mechanism with the device housing or frame, integrating the locking element and blocking element into existing structural components, thereby minimizing additional volume required

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If traditional opening mechanisms are used, then basic locking function is provided, but unauthorized opening cannot be prevented with 100% safety

Engineering Contradiction:
Improvesecurity against unauthorized accessVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical key-based or code-based locking systems with biometric fingerprint authentication, providing 100% security against unauthorized access since fingerprints are unique to each individual and cannot be easily replicated or shared

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

Solution Approach 2:

The patent uses a fingerprint template stored in memory as a digital copy of the user's biometric data, allowing for rapid comparison and authentication without physical contact with the original fingerprint after initial enrollment

Inventive Principle:
Principle #26Copying

4Productivity

If frequent activation of traditional opening mechanisms occurs, then opening function is provided, but parts get stuck and jammed making operation unreliable

Engineering Contradiction:
Improveopening operation frequencyVSAvoidfaultless opening operation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts the opening mechanism to its simplest form with minimal moving parts (only the blocking element needs to move), eliminating the possibility of parts getting stuck or jammed even with frequent activation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spring element automatically returns the blocking element to its locked position after activation, providing self-service operation that requires no manual intervention and maintains reliability through thousands of activation cycles

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to an opening mechanism comprising a locking element (38) movably arranged along a locking element axis; a blocking element (12) movably arranged along a blocking element axis, attacking in a locking position with a first end (16) at the locking element (38), whereby the locking element (38) is blocked in its freedom of movement, and which is hook-shaped at its second end (14); a spring element (32) acting along the locking element axis, and an actuating element (26) which is so configured that it can transfer the blocking element (12) by attacking at the hook-shaped second end (14) from a closed position into an open position, whereby the blocking element (12) releases the locking element (38). Thereby an opening mechanism is provided which works wear-free and reliable.
