Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current locking systems for aircraft models and similar applications face challenges such as limited durability, time-consuming assembly/disassembly, visual defects, and difficulty in accessing and operating connections, especially in small spaces, due to the use of elastic bands, screws, and visible operating elements.
Innovation Solution
A magnetic locking system that uses permanent magnets to move a bolt between unlocked and locked positions without visible external operating elements, allowing for simple, reliable, and energy-independent locking and unlocking, utilizing a combination of magnets with specific magnetization directions to achieve automatic and durable locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If elastic bands and plastic hooks are used for locking, then the locking system is simple and inexpensive, but the durability is limited due to stretching and tearing under tensile loads
Solution Approach 1:
The patent replaces the elastic band mechanical system with a magnetic field system. Permanent magnets mounted on the bolt and within the locking partner create magnetic attraction forces that eliminate the need for elastic bands, thereby improving durability while maintaining simplicity.
Solution Approach 2:
The patent changes the fundamental parameter of locking force from mechanical tension (elastic bands) to magnetic attraction (permanent magnets). This parameter change allows the locking system to withstand tensile loads without stretching or tearing, significantly improving reliability.
2Reliability
If screw connections are used for secure locking, then the connection strength and durability are improved, but the assembly and disassembly time increases significantly
Solution Approach 1:
The patent replaces the screw mechanical system with a magnetic locking system. The magnetic attraction between permanent magnets provides secure locking without requiring threading or tightening operations, reducing assembly and disassembly time while maintaining connection strength.
Solution Approach 2:
The permanent magnets are pre-mounted on the bolt and within the locking partner during manufacturing. This preliminary action eliminates the need for time-consuming screw tightening operations during assembly, as the magnetic connection is immediately effective upon engagement.
3Reliability
If screw connections and visible operating elements are used, then the locking mechanism is reliable and operable, but visual defects appear on the model surface
Solution Approach 1:
The patent extracts the operating elements (screws, knobs, or other visible components) from the model surface by implementing a contactless magnetic operating system. The permanent magnets can be actuated through the model surface without requiring visible openings or protruding elements, thereby improving aesthetic appearance while maintaining reliability.
