Optical Module Buffer With Notch For Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical modules for flat panel displays in mobile devices face challenges in design and manufacturing complexity, requiring time and cost due to intricate notch structures on plastic or metal supports, and struggle to absorb high-frequency vibrations caused by input frequencies, leading to noise and impact susceptibility.
Innovation Solution
An optical module design featuring a buffer structure with a protrusion and corresponding notch on the support, allowing for simplified manufacturing and enhanced toughness and vibration absorption, using a support with a pedestal, sidewall, and optional bottom board, and a buffer with disconnected or one-body structure to accommodate the optical film's protrusion, reducing assembly complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional notch structures are used on plastic or metal supports to fix optical films, then the optical module can be assembled, but the design and manufacturing complexity increases and time and cost are required
Solution Approach 1:
The patent extracts the fixing function from the traditional notch structure on the support and relocates it to a separate buffer component. The buffer is disposed on the support and has a corresponded notch to accommodate the protrusion of the optical film, separating the support's primary function (structural) from the fixing function (buffer's responsibility).
Solution Approach 2:
The fixing mechanism is segmented into two independent components: the support with pedestal and sidewall, and the buffer with notch structure. This segmentation allows each component to be optimized independently and simplifies manufacturing compared to integrating the notch directly into the support.
2Object-affected harmful factors
If traditional support structures are used, then the optical module can be assembled, but the ability to absorb high-frequency vibration is insufficient leading to noise
Solution Approach 1:
The buffer component is designed with material properties that provide vibration absorption capability before the high-frequency vibration occurs. The buffer acts as a pre-positioned cushioning element between the support and the optical film, absorbing vibrations caused by input frequency and preventing noise generation.
3Strength
If intricate notch structures are used on supports, then the optical film can be fixed, but the toughness against impact is reduced
Solution Approach 1:
The notch structure is extracted from the support and placed on the buffer component. This allows the support to maintain its structural integrity and toughness against impact, while the buffer (designed with appropriate material properties) carries the notch structure for fixing the optical film.
