Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional linear sawtooth arrangement is used, then manufacturing is simple, but chip removal and heat dissipation ability are poor
Solution Approach 1:
The patent applies curvature by arranging sawteeth in an arc shape rather than a straight line. The sawtooth units are positioned along a curved path, creating an arc-shaped cutting edge that improves chip removal and heat dissipation while maintaining manufacturing feasibility through standard blade forming processes
2Ease of manufacture
If traditional linear sawtooth arrangement is used, then manufacturing is simple, but cutting surface quality is rough
Solution Approach 1:
The arc-shaped arrangement of sawtooth units creates a curved cutting path that produces smoother cutting surfaces compared to linear arrangements. The curvature distributes cutting forces more evenly across the material, reducing surface irregularities and improving overall cutting quality
3Ease of manufacture
If single-type sawtooth structure is used, then manufacturing is simple, but cutting efficiency is reduced
Solution Approach 1:
The patent implements local quality by creating sawtooth units with varying tooth characteristics (different numbers of large and small teeth, varying tooth dimensions) at different locations along the arc. This localized variation optimizes cutting performance for different sections of the blade while maintaining overall structural coherence
Solution Approach 2:
The saw blade is segmented into multiple sawtooth units, each comprising a specific arrangement of large and small teeth. These discrete units are arranged along the arc, allowing each segment to perform its cutting function independently while contributing to the overall cutting efficiency
4Device complexity
If traditional linear sawtooth arrangement is used, then blade structure is simple, but vibration and impact are high
Solution Approach 1:
The arc-shaped configuration of sawtooth units distributes cutting impacts along a curved path rather than a straight line. This geometric distribution reduces concentrated vibrations and impacts at any single point, improving cutting stability and reducing blade vibration during operation

AI summary
An arc-shaped oscillating saw blade with large and small teeth and an oscillating saw are provided. The arc-shaped oscillating saw blade with large and small teeth includes a connecting part and a cutting part. Sawteeth of the cutting part are arranged in an arc shape, and a plurality of adjacent sawteeth form a sawtooth unit, and each sawtooth unit includes a plurality of large teeth and a plurality of small teeth, thus forming a structure with the large and small teeth interleaved. With structural design of the saw blade with interleaved large and small teeth, an effective cutting area of the saw blade can be increased. With design of incremented angles, the sawteeth distributed in the arc shape can be formed, which facilitates reducing of the impact and vibration in the cutting process and further improves the cutting accuracy.
