Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional assembly and welding processes are used to manufacture heat dissipating devices, then connection strength between components is ensured, but manufacturing complexity and manpower requirements increase significantly
Solution Approach 1:
The patent merges the heat dissipating module, heat pipe, and connecting structure into a single integrated component formed by injection molding. This eliminates the need for separate assembly and welding operations, reducing manufacturing complexity while maintaining structural integrity through the integrated design
2Reliability
If conventional assembly and welding processes are used to manufacture heat dissipating devices, then reliable connections between components are achieved, but production time and manpower costs increase
Solution Approach 1:
The connecting structure is pre-formed as an integral part of the heat dissipating module through injection molding before assembly. This preliminary formation of connections eliminates the need for subsequent welding operations, improving production efficiency while ensuring reliable connections are built-in from the start
Solution Approach 2:
The patent replaces the welding process (thermal/mechanical system) with an injection molding process that forms integral connections. This substitution eliminates the need for welding equipment and operators, reducing production time and manpower costs while maintaining connection reliability through the molded structure
3Strength
If welding processes are used to assemble heat dissipating devices, then component connections are secured, but automation of the manufacturing process becomes difficult
Solution Approach 1:
The patent replaces the welding process with injection molding to form integral connections. Injection molding is inherently suitable for automation, allowing the entire heat dissipating module to be manufactured in a single automated process, thereby enabling full automation of production while maintaining connection strength through the molded structure

AI summary
A heat dissipating device includes a heat dissipating module, a heat pipe, and an injection molded member formed by molding and solidifying. The heat pipe has a transfer segment, a heat input segment, and a heat output segment. The heat input segment and the heat output segment are respectively integrally extended from two opposite ends of the transfer segment. The heat input segment and the heat output segment each has a contact surface, and at least one of the contact surfaces contacts the heat dissipating module. The injection molded member connects to the heat dissipating module and a portion of the heat pipe, which contacts the heat dissipating module, for keeping the connection of the heat dissipating module and the contact surface of the heat pipe. The instant disclosure also provides a manufacturing method of the heat dissipating device by using connection of the injection molded member.
