Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heat dissipation plates are disposed misaligned to improve heat dissipation efficiency, then radiant heat transfer efficiency is improved, but air flow resistance increases
Solution Approach 1:
The patent applies the dynamics principle by making the heat dissipation plates rotatable rather than fixed. The plates can dynamically adjust their orientation angle relative to the air flow direction, allowing the system to optimize between radiant heat transfer efficiency and air flow resistance based on operational requirements. This is achieved through a rotating mechanism that enables continuous adjustment of plate positions.
Solution Approach 2:
The patent implements parameter changes by varying the orientation angle of the heat dissipation plates. By changing the angular parameter of plate arrangement, the system can switch between different operational modes: when plates are misaligned with air flow, radiant heat transfer is maximized; when plates are aligned parallel to air flow, air flow resistance is minimized. This parameter adjustment resolves the contradiction between the two opposing requirements.
2Productivity
If heat dissipation plates are aligned with air flow direction to reduce resistance, then convective heat transfer efficiency is improved, but radiant heat transfer efficiency deteriorates
Solution Approach 1:
The rotating mechanism enables the heat dissipation plates to dynamically switch between two distinct operational configurations. In the first configuration, plates are oriented to maximize convective heat transfer by aligning with air flow. In the second configuration, plates are misaligned to maximize radiant heat transfer. The system can transition between these states as needed, resolving the contradiction through temporal separation of the two functions.
Solution Approach 2:
The patent enables periodic switching between convective and radiant heating modes by rotating the plates between different angular positions. The system can alternate between these two heat transfer modes periodically, allowing each mode to operate at optimal efficiency during its active phase, thus resolving the inherent contradiction between the two modes.
3Device complexity
If a fixed configuration heater is used, then device complexity is reduced, but adaptability to different heating modes is limited
Solution Approach 1:
The patent applies the universality principle by designing a single heater system that can perform multiple heating functions through the adjustable plate configuration. The same physical heater can operate in different modes (convective heating, radiant heating, or combined modes) by changing the plate orientation, making the device versatile without requiring multiple separate heating systems.
Solution Approach 2:
By introducing rotational capability to the heat dissipation plates, the system transforms from a fixed, single-function heater to a dynamic, multi-function heating device. The plates can be rotated to different angles to achieve different heating modes, providing adaptability while maintaining a relatively simple overall structure that avoids the need for multiple independent heating systems.
