Solution Overview

Problem

Electronic devices with camera modules face optical axis misalignment due to impact-induced deformation of fixing means, leading to errors in distance calculations and image quality.

Innovation Solution

An electronic element supporting base with a fixing portion acting as a fulcrum, and a carrying part with gaps between itself, the frame, and the circuit board, allowing oscillation and preventing direct squeezing, thus maintaining optical axis parallelism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the camera is fixed rigidly to the chassis using fixing means, then the camera is securely held in place, but the optical axis shifts when the device receives an impact due to deformation of the fixing means

Engineering Contradiction:
Improvefixing strengthVSAvoidoptical axis alignment
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent applies a flexible cushioning structure (elastic component) between the camera module and the chassis to absorb impact forces. This flexible element allows the camera to maintain its position during normal operation while providing compliance during impacts, preventing optical axis shift without compromising fixing strength.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent implements a cushioning structure in advance between the camera module and the chassis that is designed to absorb impact forces before they can deform the fixing means. This pre-positioned cushioning layer protects the optical axis alignment by dissipating impact energy through elastic deformation, thereby preventing the harmful deformation that would otherwise occur.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If dual camera designs are used for triangulation distance calculation, then distance measurement capability is improved, but the requirement for parallelism of optical axes becomes more stringent

3Stability of the object's composition

If the electronic element supporting base is rigidly connected to the frame and circuit board, then structural stability is improved, but the electronic elements are prone to shifting when the device receives an impact

Engineering Contradiction:

Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent transforms the rigid static connection into a dynamic suspended structure where the electronic element supporting base can oscillate relative to the frame and circuit board through gaps. This dynamic design allows the structure to adapt to impact forces by permitting controlled movement, thereby protecting the electronic elements from permanent displacement while maintaining overall structural integrity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a cushioning structure in advance between the camera module and the chassis that is designed to absorb impact forces before they can deform the fixing means. This pre-positioned cushioning layer protects the optical axis alignment by dissipating impact energy through elastic deformation, thereby preventing the harmful deformation that would otherwise occur.

AI summary

An electronic element supporting base and an electronic device applying the same are provided. The electronic element supporting base comprises a fixing portion and a carrying part. The fixing portion is suitable for being fixed to a frame of the electronic device as a fulcrum for the electronic element supporting base. The carrying part is suitable for carrying a plurality of electronic elements, wherein a gap exists between the carrying part and the frame, and a gap exists between the carrying part and the circuit board. When the electronic device receives an impact, the suspended design of the electronic element supporting base allows the carrying part to oscillate through the gaps, and the electronic element supporting base will not be squeezed, which prevents the electronic elements on the electronic element supporting base from being shifted.
