Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact 5-terminal type telephone line tester that provides close illumination for visual inspection and alignment monitoring of densely arrayed connectors, while also allowing for operational testing of protectors and electrical access to all signal wires without disconnecting them.
Innovation Solution
A compact multifunction 5-terminal type connector compatible telephone line tester with an integrated power source, a built-in light source for illumination, and circuitry for protector testing, featuring a push switch for manual initiation and a dual LED for indicating protector condition, allowing for concurrent protector connection and testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact tester design is used to access tightly spaced protectors, then the ability to inspect densely arrayed connectors is improved, but adequate illumination for visual inspection becomes insufficient
Solution Approach 1:
The patent combines the illumination function directly into the tester body by integrating a light source that is activated when the tester is inserted into the connector. This merging of functions allows the compact tester to provide adequate illumination without requiring separate lighting equipment, resolving the contradiction between compact size and illumination adequacy.
2Reliability
If the protector is removed for testing, then operational testing of the protector is improved, but electrical connection stability deteriorates
Solution Approach 1:
The patent uses the tester itself as an intermediary device that maintains electrical connections during protector testing. The tester provides stable electrical contact points that allow the protector to be tested without removal, thereby maintaining connection stability while enabling operational testing through the intermediary testing circuitry.
3Adaptability or versatility
If multiple functions are integrated into the tester, then testing capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal tester design that can perform multiple functions including visual inspection illumination, electrical continuity testing, and protector operational testing through integrated circuitry. The testing circuit is designed to handle various test configurations through single integrated components, achieving multi-functionality without proportionally increasing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient visual inspection and alignment of connectors, reduces risk of structural damage during testing, and provides reliable protector testing and illumination in a compact, handheld device.
Implementation Method 1
a light source powered by the power source for a most direct illumination of the to be tested 5-terminal type connector
Implementation Method 2
Dual visual information of a good and bad protector condition is preferably provided by a dual light LED
Data Source
AI summary
A compact multifunction 5-terminal type compatible telephone line tester has batteries fitted in its frontal access shaft that fits into a to be tested connector between tightly arrayed protectors assembled in a cross connect box. A light powered by the battery is integrated at the tester front face in between the connection pins. The protector removed from the to be tested connector may be inserted in a terminal that laterally extends from the tester. An electric circuit tests and indicates the protector condition and switches the light on upon manual pushing of a switch. The electric circuitry is powered by the batteries. A mechanical switch is actuated by the protector housing while the protector is connected to the terminal for automated protector through connection to the to be tested connector. Lateral terminals and a jack connector on the back side provide access to the connector.
