Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fluidity of glue used in camera modules contaminates the optical members, affecting the quality of the camera in electronic devices.
Innovation Solution
A camera module design that incorporates a blocking member made of indium tin oxide, positioned between the conductive connections and the light-transmitting area, prevents glue from flowing into the optical member by forming a barrier, while also providing electrical conductivity and optical transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glue is used to connect components in the camera module, then the components are securely joined, but the optical member becomes contaminated affecting camera quality
Solution Approach 1:
A blocking member is introduced as an intermediary component between the conductive member and the optical member. This blocking member prevents glue from directly contacting the optical member while still allowing the conductive member to be securely connected to the optical member through the blocking member, thus resolving the contradiction between secure connection and contamination prevention.
2Object-affected harmful factors
If a blocking member is added to prevent glue flow, then optical member contamination is prevented, but device complexity increases
Solution Approach 1:
The blocking member is designed to serve multiple functions simultaneously: it acts as a barrier to prevent glue flow, provides structural support for the conductive member, and maintains the positional relationship between components. This multi-functionality reduces the need for additional separate components, thereby minimizing the increase in device complexity while effectively preventing contamination.
3Reliability
If blocking member material is chosen for electrical conductivity, then electrical connection is maintained, but manufacturing difficulty increases
Solution Approach 1:
The blocking member is constructed using composite materials that combine insulating properties (to block glue) with conductive properties (to maintain electrical connection). This could involve coating an insulating blocking member with a conductive material or using a composite structure that inherently provides both properties, thus maintaining electrical connection reliability while managing manufacturing complexity through material selection rather than complex assembly processes.

AI summary
A camera module includes a frame, an optical member, a wiring line, a circuit board, a conductive member, glue, and a blocking member. The frame includes a first connecting end and a second connecting end. The optical member is arranged on the first connecting end, and the optical member includes a light-transmitting area and a non-light-transmitting area. The wiring line is arranged on the non-light-transmitting area. The circuit board is arranged on the second connecting end. One end portion of the conductive member is connected to the circuit board, the other end portion of the conductive member is fixed to the wiring line by a conductive adhesive, thereby forming a connection of the conductive member, the wiring line, and the conductive adhesive. The glue covers the connection. The blocking member is arranged on the non-light-transmitting area, and the blocking member is located between the connection and the light-transmitting area.
