Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If upper and lower plate springs are fixed to a housing to support the lens module, then the lens module can be supported, but the structure becomes complex and assembly becomes difficult
Solution Approach 1:
The patent extracts the complex plate spring fixing structure from the housing and replaces it with a simplified wire member that passes through the housing. This removes unnecessary structural elements while maintaining the essential function of supporting the lens module, thereby reducing device complexity and easing assembly.
Solution Approach 2:
The wire member serves multiple functions: it supports the lens module, allows for height adjustment, and provides a simplified mounting mechanism. By consolidating these functions into a single component, the patent reduces the number of parts needed and simplifies the overall structure without compromising reliability.
2Reliability
If a complex fixing structure with plate springs is used, then the lens module can be securely mounted, but circuits for driving the camera lens assembly need to be provided on lower surface and side surface, making assembly difficult
Solution Approach 1:
The patent removes the complex plate spring mounting structure and replaces it with a simple wire member that passes through the housing. This extraction of unnecessary structural elements eliminates the need for complex circuit routing on multiple surfaces, significantly easing the assembly process while maintaining secure lens module mounting.
Solution Approach 2:
Instead of fixing the wire member to the housing from the outside (complex approach), the patent inverts the approach by having the wire member pass through the housing from one side to the other. This inversion simplifies the mounting process and eliminates the need for complex external fixing structures and multi-surface circuit routing.
3Adaptability or versatility
If the camera lens is provided on the front or rear surface of the portable terminal, then it can be integrated into the device, but impacts are often generated in a side surface direction, causing deformation or damage
Solution Approach 1:
The patent applies beforehand cushioning by providing a damping structure that absorbs impacts from side surfaces before they reach the lens module. This protective measure is built into the design from the outset, allowing the lens to be integrated into the portable terminal while protecting it from deformation or damage caused by side surface impacts during drops or shocks.
4Ease of operation
If a simplified structure with wire member is used to support the lens module, then assembly becomes easier, but the lens module needs resilient support for auto focusing and impact absorption
Solution Approach 1:
The wire member is designed to perform multiple functions simultaneously: it provides resilient support for the lens module, enables auto focusing by allowing height adjustment, and works in conjunction with the damping structure to absorb impacts. This multi-functionality maintains reliability while achieving simplified assembly.
Solution Approach 2:
The patent combines the simple wire member support structure with a damping structure that provides beforehand cushioning against impacts. This combination ensures that while the assembly process is simplified, the lens module still receives adequate protection and resilient support for auto focusing operations.

AI summary
A camera lens assembly includes: a lens holder unit to which a lens module is mounted; a wire member fixed to the lens holder unit and the lens module, and resiliently supporting the lens module such that the lens module is driven in an optical axis direction; and a fixing member mounted to the lens holder unit to fix the wire member and dampen an impact generated in the wire member due to an impact generated in a direction perpendicular to the optical axis direction. Also, a camera lens assembly can include: a wire module resiliently supporting a lens module such that the lens module is movable in an optical axis direction on a lens holder unit, dampening an impact generated in a direction perpendicular to the optical axis direction, and transferring a current applied to drive the lens module to a circuit board.
