Innovation Solution
A manufacturing method involving the use of composite door core panels made from explosion-proof, bullet-proof, high-temperature resistant, impact-resistant, anti-radiation, and fireproof materials, combined with a low-carbon steel frame, and integrated with an intelligent lock system, ensuring precise assembly and coating processes to enhance structural integrity and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ordinary security doors are used with simple structure and single materials, then manufacturing cost and simplicity are maintained, but security performance against explosions and bullets is insufficient
Solution Approach 1:
The patent applies composite materials by combining multiple layers including steel plates, explosion-proof materials, bullet-proof materials, fire-proof materials, and thermal insulation materials to create a door core panel that simultaneously achieves explosion-proof, bullet-proof, fire-proof, and insulation performance, resolving the contradiction between security performance and structural simplicity
Solution Approach 2:
The door structure is segmented into multiple functional layers (steel plates, explosion-proof materials, bullet-proof materials, fire-proof materials, thermal insulation materials) that can be manufactured and assembled separately, then combined to achieve comprehensive security performance without requiring a completely new complex structure
2Adaptability or versatility
If current bulletproof doors are used with individual bulletproof function, then manufacturing complexity is kept low, but multi-functional requirements (explosion-proof, fire-proof, anti-theft) cannot be met
Solution Approach 1:
The patent implements multi-functionality by integrating explosion-proof, bullet-proof, fire-proof, and thermal insulation functions into a single door core panel through layered composite materials, allowing one door structure to meet multiple security requirements simultaneously, thus achieving versatility without proportionally increasing manufacturing complexity
Solution Approach 2:
By using composite materials with different functional properties (explosion-proof, bullet-proof, fire-proof, insulation) layered together in the door core panel, the patent enables a single component to deliver multiple protective functions, addressing the need for multi-functional capability
3Manufacturing precision
If traditional welding and spraying processes are used, then manufacturing simplicity is maintained, but structural integrity and aesthetic quality are insufficient
Solution Approach 1:
The patent applies preliminary action by pre-assembling the composite door core panel with all functional layers (steel plates, explosion-proof materials, bullet-proof materials, fire-proof materials, thermal insulation materials) before final door assembly, ensuring precise alignment and structural integrity while simplifying the final manufacturing process
Solution Approach 2:
The patent replaces traditional welding processes with mechanical assembly methods for the composite door core panel layers, using precise cutting and fitting techniques that eliminate the need for welding while achieving high assembly precision and structural integrity
