Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching an optical lens to a barrel or optical sensor require connection components such as screws or adhesive material, increasing assembly difficulty and cost in optical data capturing devices.
Innovation Solution
An optical lens design featuring a first part protruding from a second part with a concave portion, allowing secure attachment to a base with protruding portions without connection components or adhesive material, simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If connection components such as screws or adhesive material are used to attach the optical lens to the barrel or optical sensor, then the attachment strength is improved, but the assembly difficulty and cost increase
Solution Approach 1:
The patent integrates the attachment function directly into the lens structure by forming an integrated lens assembly where the lens is molded as a single piece with attachment features (such as protrusions or engagement structures). This merging of the lens optical function and mechanical attachment function eliminates the need for separate connection components like screws or adhesives, thereby reducing assembly complexity while maintaining attachment strength
Solution Approach 2:
The lens structure incorporates self-aligning and self-securing features such as elastic deformation zones, protrusions that automatically engage with corresponding recesses in the barrel, or interference-fit designs. These features enable the lens to attach itself to the barrel or optical sensor without requiring external connection components or adhesive materials, simplifying the assembly process while ensuring secure attachment
2Reliability
If connection components such as screws or adhesive material are used to attach the optical lens, then the attachment reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The attachment features are integrated into the lens molding process itself, combining the optical lens fabrication and mechanical attachment feature creation into a single manufacturing step. This eliminates the need for separate procurement, inventory management, and assembly operations for connection components, thereby reducing manufacturing costs while maintaining reliable attachment through the integrated design
Solution Approach 2:
The lens design incorporates self-securing mechanisms such as elastic recovery features, interference fits, or snap-fit structures that are formed during the lens molding process. These features provide reliable attachment without requiring additional materials like adhesives or fasteners, thereby reducing material costs and simplifying the manufacturing supply chain while ensuring consistent attachment reliability
