Flexible Pin Vibration Isolation for Display Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibratile display devices suffer from vibration energy dissipation to the back plate due to rigid screws, resulting in a poor vibration effect on the display panel.
Innovation Solution
The use of flexible pins with an insert, lean, neck, and top portions to space the panel assembly from the back plate, preventing vibration energy dissipation and enhancing the vibration effect by absorbing and transferring energy effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid screws are used to fix the panel assembly to the back plate, then the fixing strength is improved, but the vibration energy dissipates to the back plate resulting in poor vibration effect
Solution Approach 1:
The patent changes the physical state and mechanical properties of the fastening component from rigid (screw) to flexible (pin with elastic portion). The flexible pin maintains fixing strength through elastic deformation while preventing vibration energy dissipation by absorbing energy in the elastic portion, thus resolving the contradiction between fixing strength and vibration energy loss.
Solution Approach 2:
The flexible pin is constructed as a composite structure with different portions having different functions: the insert portion provides anchoring, the elastic portion provides vibration isolation through energy absorption, and the protruding portion provides positioning. This composite design allows simultaneous achievement of strong fixing and vibration energy retention.
2Loss of energy
If cushion pads are disposed between the base and back plate to prevent vibration energy dissipation, then the vibration energy retention is improved, but the device complexity increases
Solution Approach 1:
The flexible pin serves multiple functions simultaneously: it acts as a fastening component (replacing screws), provides vibration isolation (replacing cushion pads), and enables positioning through its protruding portion. By integrating these functions into a single component, the patent reduces device complexity while maintaining vibration energy retention.
Solution Approach 2:
The patent merges the fastening function and vibration isolation function into a single flexible pin component. The insert portion provides fastening while the elastic portion provides vibration isolation, eliminating the need for separate cushion pads and reducing overall structural complexity.
3Stability of the object's composition
If the panel assembly is closely fixed to the back plate, then the structural stability is improved, but the vibration effect deteriorates due to energy dissipation
Solution Approach 1:
The flexible pin acts as an intermediary element between the panel assembly and back plate. It maintains structural stability through secure anchoring while preventing vibration energy dissipation by absorbing energy in its elastic portion, thus mediating between the requirements for stability and vibration retention.
Solution Approach 2:
The flexible pin creates a localized flexible connection point between the rigid panel assembly and back plate. This local flexibility allows the majority of the structure to remain stable while specifically addressing vibration energy dissipation at the connection point where the flexible pin is installed.
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 flexible pin design effectively retains vibration energy on the display panel, improving its vibration effect by preventing energy loss to the back plate, thereby enhancing user experience.
Implementation Method 1
the flexible pin has an insert portion, a lean portion, a neck portion and a top portion. The lean portion is located between the insert portion and the neck portion... a diameter of the lean portion is larger than a diameter of the first fixing hole

AI summary
A vibratile display device includes a back plate, a panel assembly and at least one flexible pin. The back plate has a plurality of first fixing holes. The panel assembly is fixed to the back plate and includes a base and a display panel. The base has a carrier portion and a plurality of lugs extending outward from the carrier portion. Each lug has at least one second fixing hole corresponding to the first fixing holes. The display panel is disposed on the carrier portion of the base. An insert portion of the flexible pin is inserted into the first fixing hole of the back plate, and a neck portion of the flexible pin is inserted into the corresponding second fixing hole. A lean portion of the flexible pin is located between the base and the back plate. A top portion of the flexible pin protrudes a surface of the lugs.
