Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal bracket is used for discharging accumulated electrical charge, then the discharge ability is improved, but the weight and manufacturing cost increase
Solution Approach 1:
The bracket is constructed as a composite structure combining plastic material with a conductive member (metal strip or wire). The plastic provides lightweight structural support while the conductive member embedded within it provides the electrical discharge pathway. This composite approach achieves the electrical discharge function without requiring a fully metal bracket, thereby reducing weight and cost while maintaining discharge capability.
2Reliability
If a metal bracket is used for discharging accumulated electrical charge, then the discharge ability is improved, but the manufacturing cost increases
Solution Approach 1:
The bracket combines inexpensive plastic material with a simple conductive member (strip or wire). The plastic can be molded using standard injection molding processes, and the conductive member can be added via embedding, welding, or adhesive bonding. This composite construction uses readily available, low-cost materials and standard manufacturing techniques, avoiding the need for expensive fully metal fabrication while achieving the required electrical discharge function.
Solution Approach 2:
The conductive member in the bracket can be designed as a simple, replaceable element such as a metal strip or wire that is inexpensive to manufacture. If it becomes damaged or loses conductivity over time, it can be easily replaced without replacing the entire bracket assembly. This approach reduces manufacturing costs by using cheap, easily replaceable conductive elements rather than expensive, complex metal bracket designs.
3Reliability
If a metal bracket is used for discharging accumulated electrical charge, then the discharge ability is improved, but it interferes with antenna operation
Solution Approach 1:
The plastic material acts as an intermediary between the metal housing and the conductive member. The conductive member is embedded within or attached to the plastic bracket, which provides electrical discharge pathways while electrically isolating the metal components from direct contact with the housing. This intermediary plastic structure enables charge discharge functionality while preventing the metal bracket from interfering with antenna operation, as the plastic is electrically non-conductive and does not disrupt electromagnetic signals.
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 effectively discharges electrical charge from the camera module's metal components to the housing, preventing damage and reducing manufacturing costs and weight, while avoiding interference with device antennas.
Implementation Method 1
The conductive member (363) is received in the main body (361) and electrically couples the base mounts (321) to the housing (10)
Implementation Method 2
When the camera module is in operation, an internal coil is energized, and the housing may accumulate electrical charge. The accumulated electrical charge may damage internal components of the camera module.
