Endoscope Substrate Connector Pin and Guide Hole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate connection structures in endoscopes can experience misalignment and excessive angle between connectors, leading to a loss of electrical connection when the angle exceeds an allowable limit, which is not effectively addressed by current technologies.
Innovation Solution
A substrate connection structure that includes a tubular member with a first and second substrate, a first connector, a second connector, a pin, and a guide member with a guide hole, where the pin projects from the first substrate and fits into the guide hole on the second substrate, ensuring the angle between the connectors remains within the allowable limit by adjusting the fitting gap between the pin and the guide hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are connected directly without guide members, then the connection process is simple, but misalignment occurs and the angle between connectors exceeds the allowable limit causing loss of electrical connection
Solution Approach 1:
A guide member with a guide hole is introduced as an intermediary component between the first substrate and second substrate. The guide hole guides the pin to fit precisely, ensuring proper alignment and angle between connectors. This mediator prevents misalignment and maintains electrical connection reliability without requiring complex adjustment mechanisms.
2Ease of operation
If the fitting gap between pin and guide hole is large, then assembly is easier, but the angle between connectors exceeds the allowable limit
Solution Approach 1:
The dimensions of the guide hole and pin are precisely controlled to achieve an optimal fitting gap. The guide hole is designed with specific diameter and length parameters that allow sufficient clearance for easy assembly while maintaining the angle between connectors within the allowable limit. This parameter optimization balances assembly ease with alignment precision.

AI summary
A substrate connection structure includes a tubular member, a first substrate, a second substrate, a first connector, a second connector, a first pin, and a guide member. The tubular member has a bottom portion and an opening side. The first substrate is disposed on either the bottom portion or the opening side. The second substrate is disposed on either the bottom portion or the opening side opposite to the first substrate. The first connector is disposed on the first substrate. The second connector is disposed on the second substrate and is connected to the first connector. The first pin is disposed on the first substrate. The first pin projects such as to extend from the first substrate along a direction of connection between the first connector and the second connector. The guide member is disposed on the second substrate. The guide member has a guide hole.
