Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable handles for cooking vessels require significant pressing force to disassemble and are prone to accidental detachment, posing safety risks due to the small stroke of the opening button and the risk of unintentional unlocking.
Innovation Solution
A removable handle design with a pivoting opening button that moves through a significant range, utilizing first and second thrust members to apply distinct forces for displacement, ensuring easy assembly and disassembly while preventing accidental unlocking, featuring a long lever arm for reduced force requirements and ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the opening button has a small stroke to maintain compact assembly, then the handle structure is compact, but significant pressing force is required to move the locking member
Solution Approach 1:
The opening button moves in a rotational arc along a transverse axis rather than linearly, transforming the motion from one dimension to another. This rotational movement along an arc trajectory increases the effective stroke length without increasing the linear footprint of the button, thereby reducing the force required while maintaining compact assembly.
2Ease of operation
If the opening button is easily accessible for operation, then the handle is easy to operate, but accidental pressing may cause unintended detachment
Solution Approach 1:
The opening button is inverted so that its rest position is lowered and it must be raised against gravity and spring force to activate the unlocking mechanism. This inversion means that accidental downward pressure during normal handling cannot trigger unlocking, while deliberate upward motion by the user can easily activate it, thus resolving the contradiction between ease of operation and prevention of accidental detachment.
3Length of moving object
If the lever stroke is short to maintain compact design, then the handle structure is compact, but high force is required to move the locking member beyond the intermediate position
Solution Approach 1:
The lever rotates about a pivot point rather than moving linearly, transforming its motion into rotational movement along an arc. This allows the lever to achieve a longer effective stroke distance without increasing its linear dimensions, thereby reducing the force required to move the locking member while maintaining compact design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The handle allows for easy and safe assembly and disassembly of the cooking vessel, reducing the risk of accidental detachment and enhancing user safety by distributing the force requirement over a longer stroke, making it simpler to use and more ergonomic.
Implementation Method 1
The displacement means are adapted to utilize a lever effect making it possible to reduce the force which has to be applied to the opening button
