Lens Barrel Thin-Sheet Electric Section Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens barrel position detection systems face challenges with deformation of the electric section body, leading to potential contact with adjacent conductor patterns and difficulties in miniaturization and precise positioning due to the need for screwing and thick lens engagement members.
Innovation Solution
Incorporating a thin-sheet electric section body with reinforcing sections to increase deformation resistance, allowing the sliding portions to maintain alignment with the conductor pattern without the need for screwing, thereby stabilizing the electric section's position and reducing the lens barrel's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a thin-sheet electric section body is used, then the lens barrel can be miniaturized, but the electric section body is prone to deformation
Solution Approach 1:
The patent applies local quality by adding reinforcing sections at specific locations on the electric section body. These reinforcing sections are strategically positioned to provide structural support where needed, increasing the overall rigidity of the thin-sheet body without adding material throughout the entire structure. This allows the lens barrel to maintain its miniaturized form while preventing deformation of the electric section body during operation.
2Stability of the object's composition
If the electric section body is made thicker to prevent deformation, then deformation resistance increases, but the lens barrel cannot be miniaturized
Solution Approach 1:
The patent segments the electric section body by introducing reinforcing sections that divide the thin-sheet structure into multiple zones. These reinforcing sections create a segmented architecture where the thin body is strengthened at critical points without requiring uniform thickness increase. This segmentation allows the electric section body to maintain high deformation resistance while keeping the overall lens barrel size small.
3Ease of manufacture
If the lens engagement member is made thick to accommodate screw threading, then the electric section can be secured, but the lens engagement member cannot be miniaturized
Solution Approach 1:
The patent extracts the screw mounting function from the lens engagement member by providing a separate mounting structure. The electric section body is designed with integrated mounting features that eliminate the need for threaded holes in the lens engagement member. This extraction allows the lens engagement member to be miniaturized while the electric section is secured through alternative mounting means such as snap-fits or adhesive bonding.
4Ease of manufacture
If the electric section is screwed to the lens engagement member, then secure mounting is achieved, but precise positioning becomes difficult due to displacement or production errors
Solution Approach 1:
The patent applies preliminary action by pre-forming positioning features on the electric section body that ensure accurate alignment before final mounting. The electric section body includes integrated positioning protrusions or guide features that automatically align with corresponding features on the lens engagement member or fixed tube. This preliminary positioning action compensates for potential displacement or production errors, ensuring precise positioning of the electric section relative to the conductor pattern without relying solely on screw mounting accuracy.

AI summary
A lens barrel of the present invention is provided with an electric section having a plurality of sliding portions that slide along the predetermined conductor pattern. The electric section is provided with a thin-sheet electric section body supporting the plurality of sliding portions, and a reinforcing portion is provided at the electric section body. Therefore, in the lens barrel 1, the reinforcing portion increases the deformation resistance of the electric section body that supports the sliding portions.
