Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If screw locking is used to assemble components, then components can be disassembled for repair or replacement, but the screw heads may cause damage such as denting or chipping to the component surfaces
Solution Approach 1:
The patent introduces a positioning device with a limiting mechanism as an intermediary component between the board and the assembly structure. The limiting mechanism includes a positioning portion that engages with positioning holes and a limiting portion that restricts the insertion depth of screws, preventing screw heads from contacting and damaging the board surface while still allowing secure assembly and disassembly for repair purposes
2Temperature
If heat dissipation device is assembled using screws, then the heating element can dissipate heat, but the space required for screw locking reduces the heat dissipation efficiency
Solution Approach 1:
The patent merges the positioning function and heat dissipation function into a single integrated component. The positioning device with limiting mechanism serves both to position the heat dissipation device accurately and to provide heat dissipation through its structure, eliminating the need for separate screw locking mechanisms and maximizing the heat dissipation surface area
3Object-affected harmful factors
If welding and fixation are used to assemble components, then component damage is avoided, but disassembly for repair or replacement becomes difficult
Solution Approach 1:
The patent employs a dynamic assembly system using the limiting mechanism that allows the assembly to be easily disassembled and reassembled. The positioning portion and limiting portion create a reversible connection that maintains component integrity without permanent fixation, enabling both damage prevention and easy repair through multiple assembly cycles

AI summary
A positioning device with heat dissipation effect, includes a limiting mechanism including a sleeve and an adjusting device located inside the sleeve, and a base set at the bottom side of the sleeve. The sleeve has an accommodating space for assembling the adjusting device and is provided with a non-planar heat dissipation portion. The adjusting device includes a coupling member having a connecting part and an operating part, and an elastic member sleeved on the coupling member. The base has a docking portion, and a connecting portion on one side of the docking portion for the connecting part to be assembled at the connecting portion. A first board member can be assembled at the docking portion of the base and a second board member can be assembled at the bottom of the sleeve, so that the sleeve can assist the second board member in dissipating heat.
