Anemometer with Integrated Swing Arm for Slim Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anemometers have a bulky configuration due to the radial extension of wind mill mechanism arms and the large width of centrifugal weight and wind speed indicating mechanisms, making them difficult to slim down along the axis of rotation.
Innovation Solution
The anemometer design includes a support strut with a rotary member, swing arms, a slider, links, and wind receivers, where the wind receivers are positioned to generate torque for rotating the rotary member, and a scale indicates wind speed on the support strut, allowing the configuration to be slimmed along the axis of rotation when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind mill mechanism arms extend radially from the rotary shaft and centrifugal weight mechanism is provided separately, then the anemometer can measure wind speed, but the overall configuration becomes bulky and cannot be slimmed along the axis of rotation
Solution Approach 1:
The patent combines the wind mill mechanism and centrifugal weight mechanism into a single integrated structure. The swing arm serves dual purposes: it acts as both the wind mill arm that receives wind force and the centrifugal weight arm that responds to rotational speed. This merging eliminates the need for separate mechanisms, thereby reducing the overall width along the axis of rotation while maintaining measurement functionality.
Solution Approach 2:
The swing arm is designed to perform multiple functions simultaneously. It serves as both the wind receiver arm for the wind mill mechanism and the centrifugal weight arm for the centrifugal mechanism. This multi-functionality allows the anemometer to maintain accurate wind speed measurement capabilities while achieving a slimmer profile along the rotation axis.
2Reliability
If multiple independent mechanisms are combined to form the anemometer, then the measurement functions are complete, but the device complexity increases and the configuration cannot be slimmed
Solution Approach 1:
The patent merges the wind mill mechanism and centrifugal weight mechanism into one integrated system where the swing arm serves both functions. This reduction in the number of independent mechanisms simplifies the overall device structure while maintaining complete measurement functionality.
Solution Approach 2:
The swing arm is designed as a universal component that performs multiple functions: it receives wind force, generates rotational motion, and acts as the centrifugal weight. This multi-functionality reduces device complexity by eliminating the need for separate components for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows the anemometer to be stored in a space-saving manner by slimming its overall configuration along the axis of rotation when the wind receivers are not rotating, while maintaining functionality.
Implementation Method 1
a wind receiver provided on at least one of the distal end of the swing arm and the one end of the link, the wind receiver having a position and an angle with respect to the axis so as to generate a torque for rotating the rotary member in a predetermined direction when receiving wind in a horizontal direction from a front side
Implementation Method 2
a slider that allows the support strut to pass therethrough and is guided by the support strut, the slider being slidable in the axial direction and being rotatable about the axis

AI summary
An anemometer according to the present disclosure includes: a support strut extending in a vertical direction; a rotary member connected to an upper portion of the support strut so as to be rotatable about an axis of the support strut; a swing arm having a proximal end connected to the rotary member and a distal end swingable in the vertical direction; a slider that is slidable along the support strut and is rotatable; a link having one end connected to the swing arm at a position on a more distal end side with respect to the proximal end of the swing arm and having the other end vertically rotatably connected to the slider; a wind receiver provided on at least one of the distal end of the swing arm and the one end of the link and is configured to rotate the rotary member by a wind in a horizontal direction; and a scale attached to a side surface portion of the support strut so as to allow the slider to indicate a wind speed.
