Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blades are located at high altitude to access steady fluid flow, then power generation efficiency is improved, but structural stability deteriorates and installation costs increase
Solution Approach 1:
The support structure is divided into multiple modular segments that can be assembled incrementally. The frame includes vertical support members divided into upper and lower portions, connected through joint mechanisms, allowing high-altitude blade placement without requiring a single massive continuous structure, thus maintaining stability while achieving height.
Solution Approach 2:
Different portions of the structure have optimized local properties - the upper support members are designed with specific structural characteristics for high-altitude stability, while lower portions are optimized for ground anchoring. The frame structure incorporates localized reinforcement at critical junction points where vertical and horizontal members intersect, providing enhanced stability precisely where needed without increasing overall structure weight.
2Productivity
If complex direction and angle adjustment devices are added to HAWT blades, then power generation efficiency is improved, but device complexity increases
Solution Approach 1:
The vertical axis frame structure serves multiple functions simultaneously - it provides structural support, enables blade rotation, and incorporates the adjustment mechanism. The joint connections between vertical and horizontal frame members allow automatic blade orientation adjustment without separate complex control devices, integrating support and control functions into a single unified structure.
Solution Approach 2:
The blade adjustment mechanism utilizes the natural rotational motion of the vertical axis frame itself to achieve direction and angle changes. As the frame rotates around the vertical axis, the blades automatically adjust their orientation relative to the wind flow without requiring external actuators or complex control systems, making the structure self-regulating.
3Productivity
If support device height is increased to locate blades at high altitude, then power generation efficiency is improved, but installation costs and area requirements increase
Solution Approach 1:
Instead of using a tall vertical support structure that occupies large ground area, the invention transitions to a horizontal frame configuration where the support structure extends outward from a compact central mounting point. The vertical axis frame with horizontal arms allows blades to be positioned at high altitude while the footprint remains concentrated at the base, reducing installation area requirements.
4Ease of operation
If Savonius blade uses drag force for rotation, then self-motion capability is improved, but rotational speed is limited
Solution Approach 1:
The invention combines both drag force and lift force mechanisms within the same blade design. The airfoil-shaped blades mounted on the vertical axis frame experience drag force that provides self-starting capability, while simultaneously generating lift force during rotation that accelerates the rotational speed beyond what drag alone could achieve, merging the advantages of both Savonius and lift-based designs.
