Solution Overview
Problem
Existing pastry cutters require multiple manual steps for cutting, perforating, and ejecting dough, leading to inefficiencies, inconsistencies, and potential damage to delicate pastries like wafers.
Innovation Solution
A spring-loaded pastry cutter with a detachable head and handle, featuring a grid of spikes for perforation and an internal dough pusher aided by springs for automatic ejection, allowing for simultaneous cutting, perforating, and easy removal of dough pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional manual pastry cutters are used, then the cutting function is simple and reliable, but multiple separate tools are required for cutting, perforating, and ejecting dough, increasing device complexity and operation time
Solution Approach 1:
The patent combines cutting, perforating, and ejecting functions into a single integrated pastry cutter device. The head assembly includes a cutting blade, a grid of spikes for perforation, and a spring-loaded dough pusher for ejection, all within one tool that replaces multiple separate utensils.
Solution Approach 2:
The pastry cutter is designed as a universal tool that performs multiple functions: cutting the pastry dough into shapes, perforating the cut pieces with spikes, and ejecting them from the head. This multi-functional design eliminates the need for separate cutting boards, perforating tools, and ejection mechanisms.
2Productivity
If manual multi-step process is used, then each step can be controlled individually, but the preparation time and labor effort increase significantly
Solution Approach 1:
The pastry cutter enables continuous operation where cutting, perforating, and ejecting occur in one continuous motion. The spring-loaded pusher automatically ejects the cut and perforated pastry piece as the cutter is withdrawn, allowing the user to immediately press the cutter into the next position without manual ejection steps.
Solution Approach 2:
The spring-loaded dough pusher mechanism automatically performs the ejection function without requiring manual intervention. After the cutter presses into the dough and is withdrawn, the spring mechanism self-activates to push the pastry piece out of the head, eliminating the need for the user to manually remove each cut piece.
3Manufacturing precision
If delicate pastries are handled manually after cutting, then precision can be maintained, but the pastries are prone to damage and inconsistency in shapes and perforations
Solution Approach 1:
The pastry cutter performs perforation immediately during the cutting process rather than as a separate subsequent step. The spikes are positioned on the head so that as the blade cuts the dough, the spikes simultaneously create uniform holes in each piece, ensuring consistent positioning and size before the pastry is removed.
Solution Approach 2:
The invention replaces manual handling and positioning of delicate pastries with a mechanical system that automatically holds, cuts, perforates, and ejects the pastry pieces. The head structure provides precise mechanical guidance for the cutting blade and positioning of the pastry, eliminating variability introduced by manual manipulation.
4Ease of operation
If dough pieces are removed manually from the cutter, then control over the removal process is possible, but the delicate pastries are likely to be damaged or stuck
Solution Approach 1:
The spring-loaded pusher mechanism automatically performs the ejection function without requiring manual intervention. After the cutter presses into the dough and is withdrawn, the spring mechanism self-activates to push the pastry piece out of the head, eliminating the need for the user to manually remove each cut piece.
Solution Approach 2:
The spring-loaded pusher acts as an intermediary mechanism between the cutter head and the pastry piece during removal. Instead of the user's fingers directly contacting and potentially damaging the delicate pastry, the mechanical pusher gently and uniformly propels the piece out of the head in a controlled manner.
5Ease of manufacture
If traditional cutters are used, then the structure is simple and easy to manufacture, but cleanup is tedious and time-consuming due to dough sticking
Solution Approach 1:
The pastry cutter head incorporates a grid of spikes that create a porous or perforated structure. This design prevents dough from adhering to large flat surfaces, as the spikes create small contact points that reduce sticking. The open grid structure also allows dough scraps to fall through rather than accumulate on the head surface.
Solution Approach 2:
The spring-loaded pusher mechanism actively extracts dough pieces from the head cavity after cutting. By automatically ejecting the pastry pieces, the mechanism prevents dough from remaining stuck in the head, thereby reducing the amount of residue that requires manual cleaning afterward.

AI summary
A pastry cutter is provided to efficiently cut individual wafers from rolled dough. It features a detachable head and handle, allowing the head to press into the dough to create wafers while simultaneously perforating them with a grid of spikes. The head enclosure includes a cutter edge for defining the wafer shape and cleanout apertures for easy maintenance. An internal dough pusher, aided by springs, ejects the cut wafers from the head to ensure they do not stick. The design aims to streamline the production of wafer cookies or similar thin pastries by combining cutting, perforating, and ejecting functions in a single tool.
