Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of camera lens modules in portable devices leads to inadequate space for electrical circuits, causing potential short circuits during assembly and damage from environmental or external stress due to glue contact with electrical components.
Innovation Solution
A camera lens module design where the holder is integrally formed with a recess to house the circuit and optical lens, using technologies like laser direct structuring or insert molding to embed the circuit within the holder, and incorporating a resilient member for protection and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dimensions of the camera lens module are reduced for miniaturization, then the size of the camera module is decreased, but the space for the electrical circuit becomes inadequate leading to potential short circuits and damage
Solution Approach 1:
The patent merges the holder structure with the circuit board into a single integrated component. The holder is designed with an integrated circuit board that is formed as one piece with the holder body, eliminating the need for separate assembly of these components. This integration ensures that the electrical circuit is inherently protected within the holder structure, preventing glue contact and short circuits while maintaining miniaturized dimensions.
Solution Approach 2:
The patent utilizes three-dimensional space optimization by forming recesses in the holder structure to accommodate the circuit board in a nested configuration. The circuit board is positioned within recesses of the holder, allowing vertical stacking and efficient use of internal space. This dimensional arrangement provides adequate protection and space for the electrical circuit even in miniaturized modules.
2Strength
If glue is used to connect the lens barrel with the lens holder during assembly, then the components are joined together, but the glue may contact the electrical circuit and cause unintentional short circuit
Solution Approach 1:
The holder and circuit board are merged into a single integrated component, eliminating the need for separate assembly steps where glue could contact the circuit. The integration ensures that the circuit board is formed as part of the holder structure itself, creating inherent protection against glue contamination and short circuits while maintaining strong structural connection.
3Adaptability or versatility
If the camera lens module is subjected to environmental stress or external stress, then the glue between lens barrel and holder may peel off, but this peeling breaks the electrical circuit
Solution Approach 1:
The integration of the holder and circuit board into a single piece structure eliminates the glue joint that would peel under stress. The circuit board is formed as an integral part of the holder, creating a unified structure that maintains electrical continuity even when subjected to environmental or external stresses.
Solution Approach 2:
The holder structure incorporates recesses and integrated mounting features that pre-position and secure the circuit board before stress is applied. This beforehand positioning ensures that the circuit board remains protected and electrically connected even when the module experiences environmental or external stresses.
