Imaging Device Holding Structure Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to prevent damage to the peripheral edge portion of image pickup elements in high-density buttable arrangement structures for astronomical observation telescopes, where the wiring board is closely approximated to the image pickup element, making it susceptible to damage during handling and impact.
Innovation Solution
A holding structure with a freely attachable and detachable holding member that surrounds the wiring board, featuring engaging portions on the board and the member to absorb impacts and prevent detachment, allowing for high-density arrangement without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wiring board is approximated to the area of the image pickup element as much as possible, then the imaging resolution is improved and high-density arrangement is achieved, but the peripheral edge portion of the image pickup element becomes susceptible to damage during handling and impact
Solution Approach 1:
A holding member is introduced as an intermediary component between the wiring board and the image pickup element. This holding member has a holding portion that contacts the wiring board and a protected portion that extends to cover and protect the peripheral edge of the image pickup element, thereby mediating the protection function without interfering with the close approximation of the wiring board to the image pickup element for high-resolution imaging
Solution Approach 2:
The holding member is designed with a protected portion that protrudes from the wiring board to cover the peripheral edge of the image pickup element before any impact occurs. This provides advance protection by creating a buffer zone that absorbs or deflects impacts before they can reach the vulnerable edges of the image pickup element
2Productivity
If the wiring board is approximated to the area of the image pickup element as much as possible, then high-density arrangement is achieved, but handling becomes difficult and unnecessary impact is likely to be applied
Solution Approach 1:
The holding member serves as a mediator that provides a safe contact interface for handling. Operators can grip and manipulate the holding member instead of directly touching the image pickup element or wiring board, facilitating easier and safer handling while maintaining the high-density arrangement configuration
Solution Approach 2:
The holding member can be designed with a structure that extends beyond the wiring board edges, creating a protective shell or frame that provides both structural support and a convenient gripping surface for handling, allowing the wiring board to remain closely approximated to the image pickup element

AI summary
A holding structure 100 for an image pickup device includes a back-incident type image pickup device 1 and a holding member 51 that holds the image pickup element 1, and the image pickup device 1 has an image pickup element 11 that performs imaging and a wiring board 12 electrically connected to the image pickup element 11. The holding member 51 is freely attachably and detachably attached to a side face 27 of the wiring board 12, at each of the opposing side faces 27a, 27a in the wiring board 12, a to-be-fitted portion 28 is formed, and the to-be-fitted portion 28 and a fitting portion 54 formed at the holding member 51 are fitted together. This relieves, even when an impact is applied to the image pickup device 1 during an inspection, delivery, etc., the impact to be applied to the wiring board 12 and the image pickup element 11 by the holding member 51 while suppressing the holding member 51 from coming off. Further, handling of the image pickup device 1 is facilitated, and an unnecessary impact to be applied to the image pickup device 1 is suppressed.
