1Length of moving object
If electronic components are miniaturized to make the device thinner and lighter, then the device size and weight are reduced, but component interference increases
Solution Approach 1:
A fixed member is introduced as an intermediary element between the first and second circuit boards. This fixed member physically separates the overlapping circuit boards, preventing direct contact and interference between electronic components while allowing the devices to maintain a thin profile. The fixed member acts as a mediator that resolves the spatial conflict between miniaturization and component interference.
Solution Approach 2:
The circuit boards are arranged in an overlapping configuration along the thickness dimension rather than placing all components in the same plane. By utilizing the Z-axis (thickness direction) for component arrangement, the design achieves better space utilization and reduces planar interference, while the fixed member maintains appropriate spacing in this third dimension.

If multiple circuit boards are overlapped to improve space utilization, then internal space efficiency increases, but component interference and resonance issues worsen
Solution Approach 1:
The fixed member is divided into multiple sections: a first section extending from the first circuit board, a second section extending from the second circuit board, and a third section connecting these two sections. This segmentation allows each part of the fixed member to perform specific functions - supporting individual circuit boards while maintaining separation and reducing resonance between them.
Solution Approach 2:
The fixed member serves as a mediating structure between overlapping circuit boards, providing physical separation and structural support. It prevents harmful direct contact between components on different circuit boards while maintaining the space-efficient overlapping arrangement, thereby improving both space utilization and component reliability.

If circuit boards are placed close together for miniaturization, then device size is reduced, but resonance frequencies increase causing instability
Solution Approach 1:
The fixed member acts as a damping intermediary between closely spaced circuit boards. By physically separating the circuit boards while maintaining close proximity for miniaturization, the fixed member absorbs and dissipates vibrational energy, reducing resonance frequencies and preventing instability that would otherwise occur in tightly integrated designs.
