Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional direct bonding method is used where orthodontist bonds brackets to tooth surface through visual measurement based on experience, then the bonding process can be performed without complex equipment, but the positioning accuracy is low and treatment time is prolonged
Solution Approach 1:
The patent applies preliminary action by pre-positioning brackets on a custom-made positioning plate before patient treatment. The positioning plate is fabricated based on patient-specific 3D scanned data, allowing brackets to be precisely positioned and bonded in advance. This preliminary preparation eliminates the need for time-consuming intraoral adjustments and significantly improves positioning accuracy while reducing overall treatment time.
2Measurement precision
If indirect bonding technology with hard connection is used where positioning guide plate and bracket connection support are fixed, then positioning accuracy is high, but operation difficulty increases and requires professional dental technician assistance
Solution Approach 1:
The patent implements self-service by designing a positioning plate that can be independently fabricated and used by the orthodontist without requiring assistance from dental technicians. The plate integrates bracket positioning features and can be directly applied to the patient's model or digital scan, enabling the orthodontist to perform precise bracket bonding alone, thereby simplifying the operational process while maintaining high accuracy.
3Ease of operation
If indirect bonding technology with soft connection is used where positioning guide plate has two-layer structure with soft rubber, then ease of operation improves, but positioning accuracy becomes insufficient and bracket separation rate is high
Solution Approach 1:
The patent applies composite materials by creating a positioning plate that combines rigid structural components for precise bracket positioning with selective flexible elements that facilitate easy placement and removal. This composite structure maintains high positioning accuracy while improving ease of operation, eliminating the need for soft rubber layers that cause bracket separation, and allowing the orthodontist to easily manipulate the plate without sacrificing precision.
4Productivity
If 3D printing technology is used to design and print positioning guide plate for direct bonding, then productivity improves and treatment time is reduced, but positioning accuracy is insufficient due to 3D printing accuracy limitations
Solution Approach 1:
The patent replaces the traditional 3D printing mechanical system with a more precise digital fabrication approach. Instead of relying on the limitations of additive manufacturing, the positioning plate is created using high-precision CNC machining or milling based on digital patient-specific models. This substitution of manufacturing methodology maintains the productivity benefits of digital workflows while achieving the dimensional accuracy required for precise bracket positioning.

AI summary
A mounting device for directly bonding brackets to the tooth surface includes a tray and a mounting rack. Each mounting rack is used for mounting a bracket, and the mounting rack includes a support and a positioning clamp. The tray is used as the support base for installing the mounting rack. The support is used as the fixed supporting part, with one end connected and fixed to the lingual or lip side of the tray. The positioning clamp is used as the rotating part to connect with the bracket and adjust the position of the bracket. The positioning clamp includes a damping rotation shaft, the damping rotation shaft matches with the support, the positioning clamp rotates around the support through the damping rotation shaft, and the support and the tray adopt an integrally formed structure or detachable structure.
