Endoscope Image Pickup Device Adhesive Connection Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems face challenges in achieving firm fixation and stable connection strength due to limitations in the hooking mechanism of locking claws, which can lead to weakened connections with repeated use.
Innovation Solution
An endoscope image pickup device with a lens barrel, image pickup element, holder, and signal cable connected by a connecting member featuring an adhesive layer with a filler, where the holder and connecting member are engaged at an engaging portion with a filler-containing adhesive layer, providing enhanced fixation and stability through the use of arm portions and projecting portions with a latch mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a locking claw with hooking mechanism is used to connect the holder and signal cable, then the device complexity is reduced, but the connection strength and reliability deteriorate with repeated use
Solution Approach 1:
The patent uses a composite connection structure combining mechanical locking (locking claw with hooking portion) and chemical bonding (adhesive layer). The adhesive layer fills the gap between the locking claw and holder, creating a hybrid connection that leverages both mechanical interlocking and adhesive bonding for enhanced reliability and connection strength.
2Strength
If the hooking depth of the locking claw is increased to improve fixation, then the connection strength improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The adhesive layer serves as an intermediary substance between the locking claw and holder, filling the gap and providing additional bonding. This allows the locking claw to have a simpler, shallower hooking design while still achieving strong fixation through the combined mechanical-adhesive connection system.
3Ease of manufacture
If a simple locking claw structure is used, then the ease of manufacture is improved, but the connection strength and stability deteriorate
Solution Approach 1:
The patent merges two different connection methods (mechanical locking and adhesive bonding) into a single integrated connection system. The locking claw provides mechanical interlocking while the adhesive layer provides chemical bonding, and both work together synergistically to achieve strong, stable connections that are reliable under repeated use.
