Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld torches are used for heating waterproof coils, then the heating operation can be performed manually, but the heating effect is uneven and the time required is long
Solution Approach 1:
The heating device is divided into multiple independent spray guns (at least two) that can heat different sections of the waterproof coil simultaneously. Each spray gun operates independently with its own fuel supply, allowing parallel heating operations to increase overall heating speed while maintaining manual operability.
Solution Approach 2:
Multiple spray guns are combined into a single integrated heating device mounted on the locomotive. This merging of multiple heating sources allows simultaneous heating of multiple coil sections, dramatically increasing productivity from manual single-point heating to multi-point parallel heating.
2Productivity
If multiple spray guns are used for heating at the same time, then the heating speed increases, but the fuel consumption becomes larger which leads to waste
Solution Approach 1:
The heating device incorporates a feedback mechanism where the operator can observe the heating progress and adjust the fuel supply to each spray gun accordingly. This allows optimization of fuel consumption by providing more fuel to sections that need more heating and less to sections that are already sufficiently heated, reducing overall fuel waste while maintaining high heating speed.
Solution Approach 2:
Each spray gun can be independently controlled to provide different fuel flow rates and heating intensities based on the local requirements of different coil sections. This local quality adjustment ensures that fuel is not wasted on already sufficiently heated areas while maintaining high heating speed in areas that require more intensive heating.
3Productivity
If multiple workers are responsible for heating at the same time, then the heating coverage increases, but the labor cost increases
Solution Approach 1:
The heating device is designed to be operated by a single worker who controls multiple spray guns from one location on the locomotive. The device performs the work of multiple workers automatically through its mechanical structure, with one operator managing fuel supply and ignition for all spray guns simultaneously, thereby increasing heating coverage without increasing labor requirements.
Solution Approach 2:
The single heating device mounted on the locomotive performs the function of multiple handheld torches and multiple workers simultaneously. It provides comprehensive heating coverage across the entire waterproof coil width through its multiple spray guns, replacing the need for multiple workers while maintaining or improving heating effectiveness.
4Manufacturing precision
If the waterproof coil is heated uniformly, then the heating quality improves, but the fuel consumption increases
Solution Approach 1:
The spray guns are positioned and oriented to provide locally optimized heating to different sections of the waterproof coil. Each spray gun targets specific areas that require heating, ensuring uniform overall heating while avoiding fuel waste in areas that do not require intensive heating. The local quality adjustment of each spray gun contributes to both heating uniformity and fuel efficiency.
Solution Approach 2:
The heating device is pre-positioned and pre-adjusted before operation to ensure optimal heating distribution across the coil. The spray guns are oriented and fuel flow rates are pre-configured to achieve uniform heating from the start, preventing the need for excessive fuel consumption to correct uneven heating patterns later in the process.
