Solution Overview

Problem

Conventional light source modules in projectors face difficulties in positioning and repairing power cords due to large wire diameters, leading to structural weaknesses and increased maintenance time, with fixed connections occupying internal space and limiting component configuration.

Innovation Solution

A light source module using a pin connector with wider connection pins and pluggable joints, allowing for easier assembly and maintenance, and reducing internal space occupation by orienting wires perpendicular to the connection direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the power cord is directly welded to the pad on the light emitting diode substrate, then the connection is secure, but positioning is difficult and welding and repair become complex

Engineering Contradiction:
Improveconnection securityVSAvoidpositioning ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent introduces a connector as an intermediary component between the power cord and the light emitting diode substrate. The connector has a first connection portion that connects to the power cord and a second connection portion that connects to the substrate, serving as a mediator that simplifies both connection and positioning processes while maintaining secure electrical connection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If a wire suitable for larger current is used, then the current capacity increases, but the wire diameter increases making welding and repair more difficult

Engineering Contradiction:
Improvecurrent capacityVSAvoidwelding difficulty
Core Design Contradiction:
PowerVSEase of manufacture

Solution Approach 1:

The patent segments the power transmission system into three parts: the power cord with thick wire for high current capacity, the connector that interfaces the power cord, and the substrate connection point. This segmentation allows the thick wire to be used only where high current is needed while the connector provides standardized connection interfaces that are easier to manufacture and repair

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the power cord is fixed to the pad through screw locking, then the connection is adjustable, but the screw and nut are liable to loosen or damage under pulling force and high temperature

Engineering Contradiction:
Improveconnection adjustabilityVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector uses a composite structure combining a metal shell for mechanical strength and resistance to pulling forces, with a plastic insulating portion that provides electrical insulation and thermal protection. This composite material approach maintains connection stability under high temperature and mechanical stress while preventing electrical conduction

Inventive Principle:
Principle #40Composite materials

4Reliability

If the power cord is fixed through welding or screw locking, then the connection is secure, but the direction of the power cord is hard to adjust and it occupies configuration space

Engineering Contradiction:
Improveconnection securityVSAvoiddirection adjustability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the connector detachable and reconfigurable, allowing the power cord connection direction to be dynamically adjusted. The connector can be removed and reconnected in different orientations, providing adaptability in spatial configuration while maintaining secure electrical connection through the standardized interface

Inventive Principle:
Principle #15Dynamics
