Imaging Camera Holding Member Recesses for Adhesive Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup camera configurations risk soiling or cracking of the image pickup element due to the flowing or separating of securing materials like adhesive during manufacturing.
Innovation Solution
Incorporating a holding member with recesses at its corner portions to contain and manage the securing material, preventing it from flowing and adhering to the image pickup element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If securing material is applied to bond the holder and wiring substrate, then adhesion strength is improved, but the securing material may flow or separate during manufacturing causing soiling or cracking of the image pickup element
Solution Approach 1:
A resin layer is introduced as an intermediary substance between the securing material and the image pickup element. This resin layer acts as a barrier that prevents the securing material from directly contacting and potentially damaging the image pickup element, while still allowing the securing material to perform its adhesion function. The resin layer mediates the interaction between the bonding process and the sensitive image pickup element.
Solution Approach 2:
The resin layer is applied to the wiring substrate before the securing material is applied. This preliminary action ensures that the protective barrier is in place before the securing material is introduced, preventing any potential soiling or cracking of the image pickup element during the subsequent bonding process.
2Strength
If securing material is applied to bond the holder and wiring substrate, then adhesion strength is improved, but the securing material may separate during manufacturing
Solution Approach 1:
The resin layer serves as a mediator that improves the compatibility and bonding interface between the securing material and the wiring substrate. This intermediary layer prevents direct contact between incompatible materials, reducing the risk of separation during manufacturing processes.
Solution Approach 2:
The bonding structure becomes a composite system consisting of multiple layers: the resin layer, the securing material, and the wiring substrate. This composite structure combines the advantages of different materials, where the resin layer provides both protection and bonding functionality, enhancing overall adhesion strength and stability.

AI summary
Provided are an image pickup camera and a multi-eye image pickup device that can inhibit flowing of securing material from occurring during manufacturing. The image pickup camera 100 includes: a substrate 130 on which an image pickup element 140 is mounted; an optical lens 110 configured to form a subject image on the image pickup element 140; a holding member 120 holding the optical lens 110 and surrounding a periphery of the image pickup element 140; and securing material 150 securing the substrate 130 and the holding member 120. The holding member 120 has a coupling face 121 that is a looped face opposed to the substrate 130 and that is secured to the substrate through the securing material. One section in a loop direction of the coupling face 121 includes a corner portion 122, and the holding member 120 has a recess 124 open toward the image pickup element 140, at the corner portion 122.
