1Weight of moving object
If the laptop is designed to be thinner and lighter, then the portability is improved, but the heat dissipation efficiency deteriorates due to insufficient space for heat dissipation modules
Solution Approach 1:
The hinge module incorporates sliding members that can dynamically change position between a first position (covering heat dissipation holes) and a second position (exposing heat dissipation holes). This dynamic adjustment allows the system to adapt to different operational states, exposing heat dissipation regions when needed while maintaining a compact closed state for portability.
Solution Approach 2:
The guiding slots are designed with specific inclination angles relative to axial directions, creating multi-dimensional movement paths. The first guiding slot is inclined to both the first axial direction and second axial direction, while the second guiding slot is parallel to the second axial direction. This multi-dimensional slot configuration enables the sliding members to traverse complex trajectories that simultaneously achieve linear displacement and rotational exposure of heat dissipation regions.

If a sufficient heat dissipation module is installed, then the heat dissipation efficiency is improved, but the device complexity increases
Solution Approach 1:
The hinge module serves multiple functions: it provides the primary pivoting connection between first and second bodies, enables linear displacement of the second body, controls the exposure of heat dissipation holes, and guides the movement of sliding members. By integrating these functions into a single mechanism using guiding slots and sliding members, the design avoids adding separate complex heat dissipation control systems.
Solution Approach 2:
The sliding members are disposed within the hinge module structure, with the first sliding member having a guiding slot that contains the second sliding member. This nested arrangement allows multiple moving components to be integrated within the compact hinge assembly, maximizing functionality while minimizing overall space occupation and structural complexity.
3Temperature
If the sliding members move along inclined guiding slots, then the heat dissipation region exposure is improved, but the wear resistance deteriorates due to increased friction
Solution Approach 1:
The guiding path is segmented into multiple slots with different orientations: the first guiding slot (inclined) and the second guiding slot (parallel to axial direction). The sliding members sequentially engage with these different slot segments, allowing the design to distribute wear across multiple contact surfaces rather than concentrating frictional wear on a single inclined slot throughout the entire movement range.

AI summary
An electronic device includes a first body, a second body and a hinge module. The hinge module includes a base, a first sliding member, a rotating shaft and a second sliding member. The base has a first guiding slot. The first sliding member is slidably disposed on the base and has a second guiding slot. The rotating shaft is pivotally connected to the first sliding member. The rotating shaft is connected to the second body and has a third guiding slot. The second sliding member is slidably disposed in the first to third guiding slots. When the rotating shaft pivots, the second and third guiding slots guide the second sliding member to move on the first sliding member, and the first guiding slot guides the second sliding member, the first sliding member, the
