Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet flight cases have weak locking mechanisms, which can lead to instability during transportation, potentially causing the case door to open automatically.
Innovation Solution
A high-reliability flight case with an auxiliary locking function, featuring a case body and case door with an iron shaft, inserting rods with a rebound mechanism, and hand-screwed nuts for enhanced stability and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple locking mode with inserting rods is used, then the structure is simple and direct, but the locking firmness is weak and reliability is insufficient
Solution Approach 1:
The locking mechanism is segmented into multiple independent components: inserting rods with external threads, hand-screwed nuts with internal threads, and a rebound mechanism. Each component performs a specific function, allowing the system to achieve reliable locking through coordinated action of multiple elements rather than a single complex structure.
Solution Approach 2:
The rebound mechanism introduces dynamic elements that allow the inserting rods to move automatically during the locking process. The spring-loaded rebound mechanism enables the rods to spring into place and maintain continuous contact with the connecting seats, providing adaptive locking that responds to operational forces.
2Reliability
If the locking mechanism is strengthened with hand-screwed nuts and threaded connections, then the locking firmness and stability are improved, but the operation complexity increases
Solution Approach 1:
The rebound mechanism provides self-aligning and self-latching functionality where the spring-loaded inserting rods automatically return to their locked position after being displaced. This self-service capability reduces the need for precise manual alignment and simplifies the locking operation while maintaining high stability.
Solution Approach 2:
The dynamic rebound mechanism allows the locking components to move and adjust during operation, making the locking process more forgiving of operational variations. The spring action provides automatic resetting and maintains continuous locking pressure, reducing the skill level required for operation.
3Ease of operation
If the inserting rods are made movable with rebound mechanism, then the quick opening and closing function is enabled, but the structural complexity increases
Solution Approach 1:
The rebound mechanism merges the spring element, connecting plates, and inserting rods into an integrated assembly that functions as a single dynamic unit. This combination allows the quick opening and closing function to be achieved through a coordinated action of merged components rather than separate complex mechanisms.
Solution Approach 2:
The spring-loaded rebound mechanism provides automatic return motion for the inserting rods, enabling quick closing without requiring additional actuation forces. The self-service spring action eliminates the need for complex return-spring mechanisms or manual resetting procedures.
