Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly tolerance between dual lenses in image capturing modules is too large, leading to increased errors in image signals and affecting imaging quality.
Innovation Solution
A positioning device comprising a module fixing jig with positioning grooves and blocks, and an auxiliary positioning jig with a hollow body and upper pressing member, which precisely positions the image capturing module and frame, minimizing assembly tolerance between lenses using thermosetting adhesive and clamping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional assembly methods are used for dual lenses, then the assembly process is simple, but the assembly tolerance between lenses is too large leading to increased image signal errors
Solution Approach 1:
A positioning device is introduced as an intermediary tool between the dual lenses during assembly. The positioning device includes a positioning groove that receives both lenses and positioning blocks that flexibly lean on the lenses to maintain precise relative positioning. This intermediary positioning mechanism enables tight assembly tolerance without requiring complex direct coupling between the lenses themselves.
2Manufacturing precision
If a positioning device with multiple components is used to reduce assembly tolerance, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The positioning device combines multiple functions into an integrated structure. The positioning groove and positioning blocks are merged into a single cohesive positioning mechanism that simultaneously achieves both lateral positioning and vertical pressing of the image capturing module. The hollow body structure further integrates the positioning and clamping functions, reducing the need for separate components while maintaining high positioning precision.
3Stability of the object's composition
If the image capturing module is firmly fixed in the frame, then assembly stability improves, but the ability to adjust alignment during assembly decreases
Solution Approach 1:
The positioning device employs dynamic elements that transition from a flexible positioning state to a fixed stability state. During assembly, the positioning blocks can flexibly adjust to accommodate alignment variations. Once positioning is achieved, the upper pressing member applies downward pressure to firmly fix the image capturing module in the frame, transitioning the system from a dynamic adjustment state to a stable fixed state.
