Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cradle-type hangers are inconvenient to operate and fail to effectively absorb vibrations transferred from artificial structures, causing mounted objects to shake severely due to amplified vibrations.
Innovation Solution
A vibration-proof hanger design featuring a fitting bracket with a hinge unit, a tilting arm unit, and a vibration-proof unit that includes absorption-type and rotation-type modules to absorb and mitigate vibrations, utilizing elastic members and ball joints to stabilize the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single rod boom is used in a conventional cradle-type hanger, then the structure is simple and easy to manufacture, but vibration from the artificial structure is amplified by the length of the rod, causing severe shaking of the mounted object
Solution Approach 1:
The boom is divided into multiple segments (first boom segment and second boom segment) connected by a hinge unit. This segmentation breaks the long single rod into shorter segments, reducing vibration amplification while maintaining structural simplicity and ease of manufacture.
2Adaptability or versatility
If screws are installed at both ends of the boom for rotation control, then the boom can be adjusted to form inclinations or levels, but it is inconvenient to operate the screws and the system fails when motor control is not available
Solution Approach 1:
A weight is attached to the second boom segment to provide gravitational force that automatically balances the boom segments. This partial action (using gravity instead of full mechanical screw control) makes operation much more convenient while maintaining the adaptability to form various inclinations and levels.
3Adaptability or versatility
If the boom length is increased to extend the mounting range, then the coverage area is improved, but the vibration amplification increases proportionally with the length of the rod
Solution Approach 1:
The extended boom is segmented into multiple sections that can be connected in series. Each segment remains relatively short to minimize vibration amplification, while the overall mounting range is extended by connecting multiple segments together, allowing the boom to reach farther positions without proportional vibration increase.
