Ceiling Fan Hanger With Elastic Shock-Absorbing Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fan hangers lack effective shock-absorbing mechanisms, leading to vibration and noise transmission, and are prone to fragmentation or breakage due to inadequate material durability, which compromises stability and service life.
Innovation Solution
A hanger design featuring a conical receiving opening with a stop ring and an elastic shock-absorbing cover that completely contacts the hanging spherical member, providing comprehensive vibration absorption and preventing direct contact with the hanger, even on angled ceilings, thus enhancing stability and preventing breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard hanging spherical member is used, then structural strength is improved, but vibration and noise transmission worsen
Solution Approach 1:
An elastic shock-absorbing cover is introduced as an intermediary element between the hard hanging spherical member and the hanger's receiving opening. This mediator absorbs vibration and prevents direct contact, resolving the contradiction between structural strength and vibration transmission.
Solution Approach 2:
The shock-absorbing cover is made of elastic material that can deform to absorb vibration energy. This flexible shell surrounds the rigid hanging spherical member, allowing the system to maintain strength while reducing harmful vibrations and noise.
2Object-generated harmful factors
If a plastic hanging spherical member is used, then vibration absorption is improved, but reliability and durability worsen
Solution Approach 1:
The system uses a composite structure combining a hard hanging spherical member (for strength) with an elastic shock-absorbing cover (for vibration absorption). This composite approach achieves both vibration reduction and high reliability, avoiding the fragmentation issues of pure plastic materials.
3Device complexity
If a shock-absorbing layer is only covered on a central circumferential edge, then manufacturing complexity is reduced, but adaptability to different ceiling angles worsens
Solution Approach 1:
The shock-absorbing cover is designed to cover the entire lower hemispherical surface of the hanging spherical member, not just a central circumferential edge. This comprehensive coverage ensures that regardless of the ceiling angle or orientation, the shock-absorbing material will always be in contact with the hanger, providing consistent vibration absorption and adaptability.
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
The solution effectively reduces high-frequency noise and vibration, stabilizes the ceiling fan, and extends the hanger's service life by ensuring the shock-absorbing cover maintains contact with the hanger's inner circumference, preventing fragmentation and breakage of the hanging spherical member.
Implementation Method 1
an elastic shock-absorbing cover that completely contacts the hanging spherical member, providing comprehensive vibration absorption
Implementation Method 2
electrical noises, and such noises will surely be transmitted to the ceiling via the hanging rod 13, the hanging spherical member 14 and the hanger 15, due to resonance effect

AI summary
A hanger for a ceiling fan is formed with a conical receiving opening contracted downward gradually and having a hard hanging spherical member received therein. The hanging spherical member has its outer circumference annularly provided with a stop ring whose diameter is larger than the inner diameter of the receiving opening. A shock-absorbing cover is covered around the outer circumference under the stop ring of the hanging spherical member, having its inner circumferential camber matching with the outer circumferential camber of the hanging spherical member to enable the shock-absorbing cover to stably cover the hanging spherical member, and its outer circumference completely touching the inner edge of the receiving opening, avoiding the hanging spherical member dropping downward, preventing noises from produced and effectively elevating stability of the hanger.
