Removable handle system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable handle systems for cookware often fail to securely attach and easily detach, leading to accidental removal and increased storage and transportation costs, weight, and exposure to cleaning abrasives.
Innovation Solution
A handle system with a grasping portion and a connector featuring a fixed catch, pivot fulcrum, latch lever, and biasing member, allowing secure attachment and easy release through a button-actuated mechanism, preventing accidental detachment and enabling efficient storage and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a removable handle system is designed to allow easy detachment, then storage and transportation efficiency is improved, but the handle may accidentally detach during use
Solution Approach 1:
The handle system is divided into separate components (handle and connector) that can be independently attached and detached. The connector is fixed to the cookware while the handle can be removed when not in use, enabling efficient storage and transportation while maintaining secure attachment during use through the latching mechanism
Solution Approach 2:
The latching mechanism is pre-configured with a biasing member that automatically engages the latch lever with the connector upon attachment. This preliminary latching action ensures the handle is securely fixed before use, preventing accidental detachment while allowing easy removal when needed
2Reliability
If a secure attachment mechanism is implemented, then accidental detachment is prevented, but the complexity of the handle system increases
Solution Approach 1:
The latching mechanism is designed to be self-actuating through the biasing member that automatically pushes the latch lever into the engaged position with the connector. This self-latching feature provides secure attachment without requiring additional actuators or complex control systems, maintaining simplicity while ensuring reliability
Solution Approach 2:
The latch lever acts as an intermediary element between the handle and connector, providing a simple mechanical interface that enables secure attachment. The button serves as a mediator to release the latch when needed, creating a straightforward interaction mechanism that balances security with ease of operation
3Reliability
If the handle is permanently attached to cookware, then attachment security is improved, but storage and transportation costs increase
Solution Approach 1:
The handle system is divided into separate components (handle and connector) that can be independently attached and detached. The connector is fixed to the cookware while the handle can be removed when not in use, enabling efficient storage and transportation while maintaining secure attachment during use through the latching mechanism
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 system ensures secure attachment and easy release of the handle, reducing storage and transportation costs, weight, and protecting the handle from cleaning abrasives while preventing accidental detachment during use.
Implementation Method 1
a biasing member biasing the latch lever to a latching position
Implementation Method 2
The system may be arranged wherein the elastic member is a compression spring
Implementation Method 3
a latch lever having an engagement portion, a catch portion, a fulcrum rest configured to maintain position of the latch lever on the pivot fulcrum

AI summary
Disclosed herein is a handle system comprising in one example: a grasping portion configured to be grasped by a user, the grasping portion also comprising a connecting end removably attached to a connector; the connecting end of the grasping portion comprising a fixed catch configured to mount the grasping portion to the connector so as to substantially maintain position of the grasping portion relative to the connector; the grasping portion comprising an inner surface forming a latch cavity; a pivot fulcrum within the latch cavity; a latch lever having an engagement portion, a catch portion, a fulcrum rest configured to maintain position of the latch lever on the pivot fulcrum; a button external of the grasping portion, the button configured to be actuated by a user; the button removably connected to the latch lever, wherein actuating the button rotates the latch lever, releasing the latch lever from the connector; and a biasing member biasing the latch lever to a latching position.
