Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical separation methods are used, then the structure is simple, but the separation efficiency is insufficient and friction means stick to the braking member
Solution Approach 1:
The patent employs pneumatic principles by introducing an air supply line that delivers compressed air to the friction means. The air pressure forces the friction means away from the braking member, ensuring reliable separation. This pneumatic mechanism overcomes the sticking problem that plagues traditional mechanical separation methods, significantly improving separation efficiency while maintaining acceptable device complexity.
Solution Approach 2:
The patent introduces air as an intermediary substance between the friction means and the braking member. This air layer acts as a mediator that physically separates the two components, preventing direct contact and sticking. The intermediary air flow enables reliable separation without requiring complex mechanical intervention, thus improving separation efficiency while keeping the device structure relatively simple.
2Reliability
If air flow is used to separate friction means, then separation efficiency improves, but energy consumption increases
Solution Approach 1:
The air supply operates periodically rather than continuously. Air is supplied to the friction means only when separation is needed, such as when the braking member stops rotating or when separation is required. This periodic action reduces overall air consumption while maintaining high separation efficiency when needed, thereby addressing the energy consumption concern.
Solution Approach 2:
The system adjusts air pressure parameters dynamically based on operating conditions. When the braking member is rotating, lower or zero air pressure is applied. When separation is needed, air pressure is increased to the required level. This parameter adjustment optimizes air consumption by applying energy only when necessary, reducing overall resource usage while maintaining effective separation.
3Object-affected harmful factors
If friction residues are not captured, then the device structure is simple, but environmental pollution increases
Solution Approach 1:
The patent extracts friction residues from the air flow using extraction devices positioned in the air supply line. These devices capture particles and contaminants before the air is reused or discharged. By taking out the harmful residues, the system prevents environmental pollution while maintaining a relatively simple overall device structure through targeted intervention rather than comprehensive complex systems.
Solution Approach 2:
The system separates and discards friction residues from the air flow through filtration and extraction mechanisms. The cleaned air is then recovered and reused in the braking system, creating a closed-loop approach. This process eliminates harmful emissions to the environment while the recovered air reduces overall consumption, balancing environmental protection with device simplicity.
