Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting decks often experience accidental position shifts and uneven wear due to lack of magnetic attraction on both sides, leading to incomplete cuts and reduced product lifespan.
Innovation Solution
A double-sided cutting deck design featuring a polycarbonate center board with evenly spaced holes and magnets on both sides, secured with TPU glue, ensuring even use and resistance to cutting impressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cutting deck is made magnetic on one side, then magnetic attraction is provided to prevent position shift, but only one side can be used repeatedly causing uneven wear and surface degradation
Solution Approach 1:
The cutting deck is divided into two distinct sides, each with its own magnetic layer. This segmentation allows each side to function independently as a usable surface, enabling the deck to be flipped and used on either side, thereby doubling the product lifespan while maintaining position stability throughout its extended usage period.
Solution Approach 2:
When one side of the cutting deck becomes worn or degraded from repeated use, the user can flip the deck and continue using the other side, effectively recovering a fresh usable surface. This extends the overall product lifespan without requiring replacement, while the magnetic properties on both sides ensure continuous position stability.
2Ease of manufacture
If the cutting deck uses a single-layer structure, then manufacturing is simpler, but the deck cannot be used on both sides leading to uneven wear
Solution Approach 1:
The cutting deck is divided into two distinct sides, each with its own magnetic layer. This segmentation allows each side to function independently as a usable surface, enabling the deck to be flipped and used on either side, thereby doubling the product lifespan while maintaining position stability throughout its extended usage period.
Solution Approach 2:
The cutting deck employs a composite structure with multiple layers including substrate layers and magnetic layers on both sides. This composite construction, while more complex than a single-layer design, enables dual-sided usability and extended product lifespan through the coordinated function of different material layers.
3Ease of manufacture
If magnets are placed in holes without proper securing, then assembly is simpler, but magnets may become loose causing position-shifting
Solution Approach 1:
A securing mechanism or adhesive acts as an intermediary between the magnet and the hole structure. This intermediary element firmly attaches the magnets to the cutting deck while maintaining the simple hole-based arrangement, ensuring magnets remain in place during use and prevent position-shifting without complicating the overall assembly process.
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 solution reduces position-shifting and extends the product's lifespan by maintaining a smooth, flat surface and ensuring even use on both sides, minimizing lateral tears and enhancing the cutting deck's durability.
Implementation Method 1
The TPU material, when dry, has good resistance and resilience to external pressure (the physical force from the cutting impressions during normal use), and provides good restoration quality for longer use.
Implementation Method 2
Even if the cutting decks are magnetized, the magnetic attraction is not evenly built on two sides of the decks

AI summary
Present invention teaches double-sided magnetic cutting deck. A plurality of magnets are used on both sides of a PC center board, sandwiched by an upper and a lower board, and bonded by TPU glue, which is also the same material used on the upper and lower boards. The magnets are substantially the size of the holes, so as to fit snuggly into the holes, with gap spaces between the edges of the hole to hold excess TPU glues, for better bonding of the magnets in place. Using the TPU materials on the surface (of upper and lower boards) provides longer product life due to the good resilience to physical force from the cutting impressions made during normal use.
