Problem
Existing blowers face challenges in effectively and efficiently adjusting the blowing direction without consuming excessive power, particularly in providing uniform airflow and controlling airflow patterns for comfort in indoor spaces.
Innovation Solution
The blower design incorporates a dual-tower structure with strategically positioned discharge ports and a movable gate system, utilizing the Coanda effect to direct airflow, allowing for the conversion of horizontal airflow into upward airflow, thereby enhancing airflow control and circulation within indoor spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independently driven motors are used to adjust blowing direction, then airflow direction control capability is improved, but power consumption increases
Solution Approach 1:
The patent merges the blowing direction control function into a single motor that rotates the entire blower assembly, rather than using multiple independently driven motors. This consolidation reduces the number of motors from multiple to one, thereby reducing power consumption while maintaining the capability to adjust blowing direction through single-unit rotation.
Solution Approach 2:
The single motor serves multiple functions: it drives the fan blades for air generation and simultaneously controls the blowing direction by rotating the entire blower assembly. This multi-functionality eliminates the need for separate motors for direction control, reducing overall power consumption while maintaining versatile direction adjustment capability.
2Adaptability or versatility
If multiple independently driven motors are used to adjust blowing direction, then direction adjustment flexibility is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple motor functions into a single motor system that performs both air generation and direction control. This merging reduces device complexity by eliminating multiple independent motor assemblies, control systems, and mounting structures, while maintaining flexible direction adjustment through the rotation capability of the single motor-driven assembly.
3Ease of manufacture
If conventional discharge port design is used, then manufacturing simplicity is maintained, but airflow uniformity deteriorates
Solution Approach 1:
The patent applies local quality by designing discharge ports with specific geometric characteristics (curved surfaces, optimized angles, and distributed positioning) at critical locations where airflow generation occurs. This localized optimization of port geometry improves airflow uniformity and circulation patterns without requiring complex manufacturing processes for the entire blower structure.

AI summary
A blower includes a first tower and a second tower spaced apart from each other each having discharge ports that face each other. A gate is movably installed in at least one of the first tower or the second tower to protrude into and out of the space between the first and second towers to change a flow of air discharged out of the discharge ports. A guide motor may be configured to move the gate. The discharge ports may be provided at a rear side of the space to discharge air toward a front of the space, while the gate may be moved to cover the front side of the space to guide air upward.
