Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fan components, air guiding components and air blocking components are arranged based on the structure of the electronic device, then the thermal dissipation module can be integrated into the electronic device, but misplacement of these components may occur causing decreased thermal dissipation efficiency
Solution Approach 1:
The patent applies asymmetry by designing fixing slots with different widths (first width, second width, third width) and different distances from the middle plane. This asymmetric configuration ensures that each component (fan, air guiding, air blocking) can only be installed in its correct position, preventing misplacement while maintaining integration into the electronic device structure.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the frame with multiple fixing slots of varying dimensions and positions before component installation. This pre-established asymmetric slot configuration guides the components into their correct positions during assembly, ensuring proper placement before the thermal dissipation system becomes operational.
2Ease of operation
If components are misplaced, then the assembly process becomes simpler and more flexible, but thermal dissipation efficiency decreases causing overheating and potential damage
Solution Approach 1:
The asymmetric fixing slots with different widths and distances create a foolproof assembly system where components can only be installed correctly. This maintains assembly flexibility while eliminating the risk of misplacement that would lead to overheating and damage.
Solution Approach 2:
The patent applies preliminary anti-action by designing the fixing slots to physically prevent incorrect component placement. The asymmetric dimensions create mechanical interference that blocks misplacement before it can occur, thereby preventing the harmful effects of improper assembly.
3Ease of manufacture
If fixed width fixing slots are used for all components, then the manufacturing process is simplified, but component placement precision cannot be ensured
Solution Approach 1:
The patent applies local quality by varying the widths of fixing slots at different locations (first width, second width, third width) and at different distances from the middle plane. This localized differentiation ensures each component fits precisely in its designated position while keeping the overall manufacturing process relatively simple.
Solution Approach 2:
The asymmetric slot dimensions provide precise component placement without requiring complex manufacturing. Each slot's unique width and position creates a simple yet effective positioning system that ensures manufacturing precision through geometric constraints rather than complex processes.

AI summary
A fan module comprises a frame and at least one filling component. The frame comprises a base plate and a plurality of partition plates. A plurality of air flow channels are formed by the base plate and the plurality of partition plates. Each partition plate has a first fixing slot, a second fixing slot, a third fixing slot and a fourth fixing slot that are located at a side away from the base plate in sequence. The first fixing slot has a first width. The second fixing slot has a second width. The third fixing slot has a third width, and the fourth fixing slot has a fourth width. The filling component is filled in the air flow channels. The first width is the same as the third width. The first width, the second width and the fourth width are different from one another.
