Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If bristles are made thick and rigid for cleaning strength, then cleaning effectiveness is improved, but durability deteriorates due to bending, splintering, and breaking
Solution Approach 1:
The patent changes the physical state of the bristles by transforming them from rigid structures into spring coils. This parameter change allows the bristles to maintain cleaning effectiveness through elastic deformation while avoiding the brittleness and breakage associated with rigid materials. The spring coil configuration enables the bristles to flex and recover, significantly improving durability.
Solution Approach 2:
The patent creates a composite structure where spring coils are embedded within a matrix material. This composite design combines the flexibility and elastic recovery of the spring coils with the structural support of the matrix, achieving both cleaning effectiveness and enhanced durability that neither material could provide alone.
2Stability of the object's composition
If bristles are made rigid for structural strength, then brush structure stability is improved, but safety deteriorates due to bristle fragments attaching to food
Solution Approach 1:
The patent transforms the bristle structure from rigid to elastic through the spring coil configuration. This parameter change allows the bristles to deform elastically under stress and return to their original shape, preventing the permanent deformation and fragmentation that occurs with rigid bristles. The elastic nature ensures structural stability without the hazard of breaking into fragments.
Solution Approach 2:
The spring coil structure acts as a cushioning element that absorbs and dissipates mechanical stresses before they can cause catastrophic failure. The coiled structure provides multiple stages of deformation, cushioning the impact and preventing sudden breakage that would release fragments into food.
3Reliability
If bristles are made flexible to prevent breaking, then durability is improved, but cleaning effectiveness deteriorates due to insufficient cleaning force
Solution Approach 1:
The patent creates a composite structure where spring coils provide flexibility and elastic recovery while the matrix material provides structural support and force transmission. This combination maintains cleaning effectiveness by ensuring the brush can transmit sufficient force to the surface being cleaned, while the spring coil component prevents breakage through elastic deformation.
Solution Approach 2:
The patent introduces dynamic behavior to the bristles through the spring coil structure. Instead of static rigid or flexible bristles, the spring coils can dynamically adjust their stiffness based on the applied load, providing firm contact for effective cleaning while maintaining the ability to flex and recover without breaking.

AI summary
A twisted wire brush comprises a twisted wire core, and first and second lengths of spring coil. The twisted wire core comprises a first core wire intertwined with a second core wire. The first and second lengths of spring coil extend about the first core wire, and the second length of spring coil extends about the first length of spring coil. The first and second lengths of spring coil are pressed between the first core wire and the second core wire. In another embodiment, a method of making a twisted wire brush comprises providing a first and a second core wire, positioning a first length of spring coil to extend inside a second length of spring coil, and the first and second lengths of spring coil to extend about the first core wire, and twisting the first core wire and the second core wire about a core axis.
