Motorized Can Opener Eccentric Gear Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional can openers require manual force and effort to cut and remove cans, making the process difficult and labor-intensive.
Innovation Solution
A can opener with a button-activated mechanism that uses a motor, transmission device, eccentric gear, and torsion spring to automatically open cans and detach from them, reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional can opener uses a manually operated cutter, then the device structure remains simple, but the operation becomes forceful and difficult
Solution Approach 1:
The patent replaces the manual mechanical cutting system with an automated system using a motor (31), transmission device (30), and eccentric gear (40) mechanism. The motor drives the cutter through the transmission device, eliminating the need for manual force application while maintaining the cutting function.
Solution Approach 2:
The can opener is designed to automatically clamp onto the can, cut it, and detach without requiring user intervention during the cutting process. The torsion spring (S) and magnetic attraction element (29) enable automatic engagement and release, making the device self-servicing throughout the operation cycle.
2Extent of automation
If a can opener is designed for automatic operation, then user effort is reduced, but the device complexity increases due to additional components
Solution Approach 1:
The patent combines multiple functions into integrated components. The motor (31) and transmission device (30) are housed within the first holder (10), the eccentric gear (40) integrates the cutting and clamping actions, and the torsion spring (S) simultaneously provides both engagement force and release mechanism. This merging reduces the number of separate components needed.
Solution Approach 2:
The cutter serves multiple functions: it cuts the can lid, clamps onto the can during operation, and is automatically released after cutting. The magnetic attraction element (29) and torsion spring (S) combination provides both engagement and release functions, making these components multi-functional rather than requiring separate mechanisms for each action.
