Conductive Spring Camera Module Securing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with integrated camera modules face assembly issues due to their small form factor, leading to dislodgment and misalignment during assembly, and existing mounting solutions like pins can break under vibration or incorrect engagement.
Innovation Solution
A securing member with spring members formed from electrically conductive material is used to secure the camera module, providing a retaining force and electrical grounding, while techniques like laser ablation and alignment members improve concentricity and alignment, and magnetically inert materials manage magnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting pins are used to secure the camera module, then the camera module can be fixed in position, but vibration or movement may cause the camera module to become dislodged and the mounting pins may break
Solution Approach 1:
The patent applies beforehand cushioning by incorporating spring members that provide continuous elastic force to maintain contact between the camera module and housing. The spring members are pre-loaded to compensate for vibrations and movements before they occur, preventing dislodgment without requiring rigid, fragile mounting pins.
Solution Approach 2:
The patent changes the mechanical parameter from rigid fixed mounting to elastic spring-based mounting. By transitioning from rigid mounting pins to spring members with controlled elasticity, the system achieves both secure positioning and vibration resistance, eliminating the brittleness issue while maintaining securing reliability.
2Volume of moving object
If the camera module is made small to fit within the housing, then the device form factor is reduced, but assembly issues such as dislodgment and misalignment occur
Solution Approach 1:
The patent applies local quality by providing enhanced securing features at specific locations on the housing and camera module. Alignment features and spring member positions are strategically placed at critical locations to ensure precise positioning and secure attachment, compensating for the small overall size of the camera module.
Solution Approach 2:
The patent applies preliminary action through pre-formed alignment features and pre-loaded spring members that are prepared in advance during manufacturing. These features ensure correct positioning and secure attachment during assembly, eliminating misalignment issues even with the reduced camera module size.
3Reliability
If a cowling is used to secure the camera module to the housing, then the camera module can be fixed, but incorrect engagement may cause the mounting pins to break
Solution Approach 1:
The patent applies self-service through spring members that automatically engage with corresponding features on the camera module and housing. The elastic nature of the spring members provides self-aligning and self-adjusting capabilities during assembly, eliminating the need for precise manual positioning and reducing the risk of incorrect engagement that could break mounting pins.
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 secures the camera module, prevents dislodgment, and provides electrical grounding, enhancing assembly precision and reducing component breakage, while maintaining magnetic balance within the device.
Implementation Method 1
The securing member may include a first spring member and a second spring member. In some embodiments, the first cavity receives the first spring member. Also, in some embodiments, the second cavity receives the second spring member.
Implementation Method 2
The securing member may include several spring members formed from an electrically conductive material. In some embodiments, when the internal component engages the several securing members, the base portion and the several spring members define an electrical grounding path to electrically connect the internal component to the housing.

AI summary
An electronic device having a securing member for a camera module is disclosed. The securing member may include several flexible spring elements extending around the camera module to maintain the position of the camera module during an assembly process of the electronic device. The securing member and the housing may be made from an electrically conductive material or materials. In this manner, the securing member may further provide the camera module with an electrical ground to prevent excessive electric charge within the camera module. In some embodiments, an alignment member is positioned on the housing and aligns the camera module and/or securing member with an aperture of the housing.
