Camera Module Filter Support Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly stability of a filter in a camera module decreases as the size of the sensor increases, leading to potential collisions and instability.
Innovation Solution
A camera module design featuring a support mechanism with substrates, support frames, and buffers that provide effective support to the filter, ensuring stability and integrity even with increased suspended areas, using optional configurations such as multiple support frames and substrates, lap joint notches, clamping parts, and elastic buffers to absorb vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the size of the sensor is increased to improve photographing pixels, then the suspended area of the filter increases, but the assembly stability of the filter decreases
Solution Approach 1:
The support mechanism is divided into multiple components: substrates, support frames, and buffers. The substrates are distributed on the periphery of the sensor, and support frames are disposed on the substrates, creating a segmented support structure that stabilizes the filter across its entire suspended area
Solution Approach 2:
Buffers are introduced as intermediary elements disposed between the substrates and support frames. These buffers absorb shaking moments and provide effective support, preventing direct transmission of vibrations from the large suspended filter area to the substrate, thereby maintaining assembly stability
2Area of moving object
If the suspended area of the filter increases, then the shaking moment of the filter acting on the support frame increases, but the support frame stability decreases
Solution Approach 1:
Buffers are pre-installed between the substrates and support frames to provide beforehand cushioning. When the filter experiences vibrations or shaking moments due to its large suspended area, the buffers absorb these shocks in advance, preventing the support frame from shaking significantly and maintaining its stability
3Reliability
If multiple support frames and substrates are used to improve filter stability, then assembly stability improves, but device complexity increases
Solution Approach 1:
Instead of uniformly supporting the entire filter area, substrates and support frames are strategically distributed only on the periphery of the sensor and filter. This localized support approach provides sufficient stability for the large suspended area while minimizing the quantity of components needed, thereby controlling device complexity
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 significantly reduces the probability of collisions and ensures assembly stability and integrity of the filter, allowing for larger photographing pixels and improved imaging quality while maintaining manufacturing cost control.
Implementation Method 1
the buffers each are disposed between the substrate and the support frame... the buffers each can provide effective support between the support frame and the substrate... vibration between the filter and the support frame is further reduced

AI summary
A camera module and a terminal device are disclosed. The camera module includes a support mechanism, a filter and a sensor disposed corresponding to the filter, where the support mechanism includes substrates, support frames and buffers, the support frames each are disposed on the substrate, an edge of the filter is fixed on the support frame, and the buffers each are disposed between the substrate and the support frame. In this way, even if a suspended area of the filter increases relative to the sensor and shaking moment of the filter acting on the support frame increases, the support frame does not shake significantly relative to the substrate, and can keep its own stability under effective support by the buffer, which significantly reduces a probability of collision between the support frame and the filter, thereby ensuring assembly stability and integrity of the filter when the suspended area increases.
