Automatic Egg Cracker with Side-Impact Cracking to Reduce Liquid Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic egg crackers face issues with egg liquid stagnation and waste due to the method of cracking from bottom to top, requiring external pressure to prevent egg shells from flying away and needing additional devices for shell dropping, which occupy space.
Innovation Solution
An automatic egg cracker with symmetrically arranged egg holders and egg-cracking knives that impact eggs from the side, using a push rod to drive the knives open and a trigger mechanism for automatic shell dropping, eliminating the need for external devices and optimizing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the egg is cracked from bottom to top, then the eggshell can be opened, but the egg liquid flows and stagnates in the dam formed by the egg-cracking knife, causing waste
Solution Approach 1:
The patent inverts the traditional bottom-to-top cracking method by implementing side cracking. The egg-cracking knife strikes the egg from the side surface, creating a crack that opens laterally rather than vertically. This inversion prevents the formation of a dam structure that would cause egg liquid to stagnate and waste, allowing the egg liquid to flow naturally through the crack without obstruction.
Solution Approach 2:
The patent transitions from vertical cracking (bottom to top) to horizontal cracking (side to side). By changing the dimension of the cracking action from vertical to horizontal, the egg liquid flow path is opened up and not blocked by the knife structure, eliminating the stagnation problem while maintaining effective shell opening.
2Force
If the egg is cracked from bottom to top, then the eggshell can be opened, but pressure is needed to press the upper end of the egg to prevent it from flying away
Solution Approach 1:
Instead of pressing the egg from above during cracking, the patent inverts the approach by striking the egg from the side. This side-impact method naturally secures the egg in position during cracking without requiring additional pressing force from above, eliminating the need for complex egg pressing devices while still achieving effective shell opening.
Solution Approach 2:
The egg holder with upward opening and the side-cracking method work together to self-stabilize the egg during the cracking process. The egg is positioned in the holder with the opening facing upward, and the side impact creates a crack that opens without requiring external pressing force, allowing the system to serve itself without additional complex components.
3Extent of automation
If external auxiliary devices are used to blow off the eggshell, then the shell can be dropped, but the mounting space is increased
Solution Approach 1:
The patent merges the egg holder and egg-cracking knife into a single integrated unit that performs multiple functions. The egg holder with upward opening not only positions the egg but also facilitates automatic shell dropping after side cracking. By combining these functions into one structure, the system achieves automatic shell removal without requiring separate auxiliary devices, thereby reducing the overall mounting space.
Solution Approach 2:
The egg holder is designed with multi-functionality: it positions the egg during side cracking, supports the egg during the cracking process, and automatically drops the shell after cracking. This universal design eliminates the need for dedicated shell dropping devices, achieving automation while minimizing space requirements.
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
Prevents egg liquid stagnation, stabilizes the egg during cracking, and enables automatic shell dropping without additional devices, improving space utilization and reducing waste.
Implementation Method 1
An elastic egg blade member is arranged between the left blade connecting member and the right blade connecting member
Implementation Method 2
an energy storage device configured for pushing the egg-cracking knife to crack the egg is arranged at one end of the side edge of the sliding block close to a locking direction
Implementation Method 3
The left blade and the right blade are slidably mounted in a sliding groove in an upper portion of the fixing frame by means of the sliding block

AI summary
Disclosed in the present disclosure is an automatic egg cracker. The automatic egg cracker includes two symmetrically-arranged egg holders and two symmetrically-arranged egg-cracking knives, where the egg holders are provided with upward openings to form egg troughs, and the egg-cracking knives impact eggs from side surfaces for cracking. A push rod is arranged behind the egg holder to synchronously drive at least one side of the egg-cracking knife to open to crack the egg. The egg trough having the upward opening is arranged, the egg is placed in the egg trough, and the egg-cracking knife impacts the egg from the side surface for cracking, such that egg liquid between the egg-cracking knife and an eggshell will not stagnate to avoid waste, and the egg is stably placed in the egg trough and will not fly away in a cracking process.
