Motor-Driven Support Mechanism for Variable Weight Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support mechanisms for throwing systems in air vehicles and carrying systems fail to efficiently hold weights of different dimensions and shapes at a desired position, lacking the ability to adjust lengthwise and rotate effectively to support weights from a single point.
Innovation Solution
A support mechanism comprising a motor-driven first rod that rotates and a transfer member allowing a second rod to move radially, with a bearing that contacts the weight for support, enabling the mechanism to adjust its length and position to hold weights effectively by rotating around its axis and moving linearly, forming a scissor-like structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a support mechanism uses fixed-length support members, then the structure is simple, but it cannot efficiently hold weights of different dimensions and shapes at a desired position
Solution Approach 1:
The support member is designed with dynamic extendability, allowing it to change its length from a retracted state to an extended state. This dynamic characteristic enables the support mechanism to adapt to weights of different dimensions and shapes while maintaining structural simplicity through a controlled transformation mechanism.
Solution Approach 2:
The support member employs a nested structure where components are arranged concentrically, allowing the support member to extend and retract along its longitudinal axis. This nesting arrangement enables variable length adjustment without significantly increasing the overall structural footprint or complexity.
2Ease of operation
If a support mechanism uses extended and retracted support members to reach different distances, then it can support weights at desired positions, but the mechanism becomes more complex
Solution Approach 1:
The support member serves multiple functions: it provides structural support, enables positional adjustment through extension and retraction, and facilitates rotational movement. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving ease of operation for supporting weights at desired positions.
Solution Approach 2:
The support member transitions between static and dynamic states, extending and retracting as needed to reach desired positions. This dynamic behavior allows the mechanism to adapt to different operational requirements without requiring entirely different structures for each position, simplifying overall operation.
3Reliability
If the support member rotates around its axis, then it can contact and support the weight effectively, but the control mechanism becomes more complex
Solution Approach 1:
The support member is designed to rotate around its own longitudinal axis using its own structural properties and the forces applied during extension and retraction. This self-rotating capability eliminates the need for separate rotational actuators or complex control mechanisms, thereby maintaining reliability while minimizing system complexity.
Solution Approach 2:
The rotational function is merged with the extension and retraction movements of the support member. The same mechanical actions that enable length adjustment also facilitate rotation around the longitudinal axis, reducing the number of independent control systems needed and simplifying the overall mechanism.
