1Temperature

If the buffer component is used to transfer heat from electronic elements to the housing, then heat dissipation is improved, but local temperature increases and affects user experience

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The buffer component is segmented into multiple regions with different thermal conductivities. The first region (first buffer portion) has higher thermal conductivity for efficient heat transfer, while the second region (second buffer portion) has lower thermal conductivity to reduce heat transfer to the housing, creating a gradient structure that balances heat dissipation and user comfort

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the buffer component are assigned different thermal properties tailored to their specific functions. The first buffer portion is designed with higher thermal conductivity to handle heat from high-power elements, while the second buffer portion uses lower thermal conductivity material to protect the housing and improve user experience in contact areas

Solution Approach 1:

The buffer component is divided into multiple independent buffer portions, each positioned between specific electronic elements. This segmentation creates thermal isolation zones that prevent heat interference between closely spaced elements while maintaining compact device dimensions

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buffer component acts as an intermediary thermal management layer between electronic elements and the housing. It mediates heat transfer by providing controlled thermal pathways, allowing heat to be dissipated efficiently while preventing harmful heat interference between components

AI summary

This application relates to an electronic device. The electronic device includes a housing, a buffer component is connected to the housing, a first electronic element is located on a side that is of the buffer component and that is away from the housing, and a second electronic element is located on a side that is of the housing and that is away from the buffer component. The buffer component has a recess, and at least a part of a front projection of the second electronic element in a thickness direction of the electronic device falls within a front projection of the recess. Disposing the recess can reduce a direct or an indirect contact area between the buffer component and the first electronic element and/or a direct or an indirect contact area between the buffer component and the second electronic element, to reduce heat transfer efficiency of a corresponding region of the buffer component and reduce heat transfer efficiency of the electronic device in the thickness direction, thereby making heat more uniform in a non-thickness direction, reducing a possibility that a local temperature of the first electronic element is relatively high, and improving heat experience of a user.
