Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the heat dissipation device is sealed with a fixed amount of phase change working medium, then the device structure is simple and reliable, but the device can only be applied to specific heat fluxes and cannot adapt to varying heat dissipating requirements
Solution Approach 1:
The patent applies the dynamics principle by making the previously static sealed structure dynamic through the addition of a valve mechanism. The valve can switch between open and closed states, allowing the accommodating chamber to transition from a sealed fixed-state to an adjustable state. This enables the phase change working medium amount to be modified according to different heat flux requirements, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent applies the parameter changes principle by enabling modification of the phase change working medium amount parameter. Through the valve mechanism, users can add or remove phase change working medium from the accommodating chamber, thereby changing the working parameter of the heat dissipation device to adapt to different heat flux conditions, while maintaining the basic sealed structure for reliability.
2Adaptability or versatility
If the heat dissipation device allows adjustment of phase change working medium amount, then the device becomes versatile for different applications, but the device structure becomes more complex
Solution Approach 1:
The patent applies the segmentation principle by dividing the heat dissipation device into distinct functional modules: the accommodating chamber for phase change working medium, the valve mechanism for control, the mounting hole for valve installation, and the heat dissipation components. This modular segmentation allows the adjustment function to be added independently while maintaining the integrity and simplicity of the original sealed structure, thus reducing the impact on overall device complexity.
3Adaptability or versatility
If the valve is added to enable opening and closing of the accommodating chamber, then the phase change working medium can be adjusted, but the sealing reliability may be compromised
Solution Approach 1:
The patent applies the preliminary action principle by providing a mounting hole that is pre-designed and pre-positioned in the accommodating chamber wall. This preliminary structural preparation ensures that when the valve is installed, it can achieve proper sealing without compromising the chamber's integrity. The mounting hole is strategically positioned and dimensioned to maintain sealing reliability while enabling future adjustment operations.

AI summary
A heat dissipation device (1) includes a heat absorbing member (10) being provided with a first accommodating chamber (11) for accommodating a working medium (60) and a mounting hole (12) in communication with the first accommodating chamber (11); and a valve (30) installed in the mounting hole (12). The valve (30) is adjustable between a first state and a second state to change the first accommodating chamber (11) between a closed state and an open state. When the first accommodating chamber (11) is in the open state, the first accommodating chamber (11) is in fluid communication with outside so that the working medium (60) can be injected into or discharged from the first accommodating chamber (11), so as to adjust the amount of the working medium (60) in the first accommodating chamber (11). Thus, the heat dissipation device (1) is applicable to various applications with different heat dissipating requirements.
