Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding knives with elastic locking plates face security risks due to direct finger pressure for unlocking, leading to unstable locking and potential deformation, distortion, and accidental unlocking.
Innovation Solution
A locking structure for folding knives utilizing an elastic locking plate with an unlocking button and a reset spring, featuring a pivot with a guide groove and a Z-shaped locking part, ensuring safe and reliable operation through controlled deformation and reset mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the elastic locking plate is pressed directly by fingers to deform for unlocking, then unlocking is achieved, but security risks and stability are compromised
Solution Approach 1:
An unlocking button is introduced as an intermediary component between the user's finger and the elastic locking plate. The button transmits the unlocking force through a controlled mechanism (pressing the front end of the locking plate) rather than direct finger pressure, preventing accidental unlocking while maintaining ease of operation.
Solution Approach 2:
The unlocking function is segmented into distinct components: the unlocking button, the elastic locking plate, and the guide groove mechanism. This segmentation allows the unlocking action to be performed through a specific sequence (pressing the button, which moves along the guide groove to press the locking plate) rather than direct finger pressure, improving both safety and reliability.
2Ease of operation
If the elastic locking plate is used for locking, then the locking function is achieved, but the plate may deform or distort leading to accidental unlocking
Solution Approach 1:
The guide groove acts as a mediator that constrains the movement of both the unlocking button and the elastic locking plate. By limiting their movement paths, the guide groove prevents excessive deformation or distortion of the locking plate, maintaining its structural integrity and resilience while still allowing proper locking and unlocking functions.
Solution Approach 2:
The guide groove changes the movement parameters of the locking plate by constraining it to a specific path. This parameter control ensures the plate deforms only within safe limits during unlocking and returns to its original position reliably, preventing permanent deformation or distortion that could lead to accidental unlocking.
3Reliability
If the elastic locking plate adapts to the blade for locking, then locking is completed, but the design is not sufficient to ensure resilience
Solution Approach 1:
The guide groove serves as a mediating structure that enhances the resilience of the elastic locking plate without adding complex external mechanisms. By providing a constrained path for the locking plate's movement, the guide groove ensures the plate maintains its elastic properties and returns reliably to the locked position, improving locking reliability while keeping the design relatively simple.
