Storage Medium Spacer Layout Using Off-Board Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face challenges in reducing the size and cost due to the need for space on the circuit board to accommodate positioning structures for storage media, limiting the degree of freedom in circuit board size and layout.
Innovation Solution
The electronic device incorporates a member different from the circuit board, such as a lower board shield, with positioning portions to support the storage medium, allowing the spacer to be positioned along the circuit board and reducing the need for space on the circuit board, thereby increasing the freedom in size and layout.

Engineering Contradiction Analysis
1Manufacturing precision
If positioning structures are provided on the circuit board for defining the position of a spacer, then the spacer can be positioned correctly to support the storage medium, but the circuit board size cannot be reduced due to the space required for these positioning structures
Solution Approach 1:
The positioning structures are extracted from the circuit board and relocated to a separate support structure. This allows the circuit board to be reduced in size while the support structure provides the necessary positioning functions for the spacer, resolving the contradiction between positioning accuracy and circuit board area.
Solution Approach 2:
The support structure is divided into multiple components: a base structure that attaches to the circuit board, and positioning portions that extend to define spacer positions. This segmentation allows the positioning function to be separated from the circuit board while maintaining functional integration.
2Manufacturing precision
If positioning structures are provided on the circuit board, then the spacer position can be defined, but the degree of freedom in circuit board layout is limited
Solution Approach 1:
By extracting positioning structures from the circuit board to a separate support structure, the circuit board gains layout freedom while the support structure maintains precise spacer positioning capabilities through its dedicated positioning portions.
Solution Approach 2:
The support structure serves multiple functions: it provides mechanical support for the storage medium, defines spacer positions through positioning portions, and allows flexible circuit board layouts. This multi-functionality resolves the contradiction between positioning precision and layout adaptability.

AI summary
There is provided an electronic device that can increase the degree of freedom of the size and layout of a circuit board. The electronic device has a circuit board, a connector mounted on an upper surface of the circuit board, with a first end of a storage medium being connectable to the connector, and a spacer that is attachable to and detachable from a member different from the circuit board and that supports a second end of the storage medium. The member different from the circuit board has at least one positioning portion for positioning the spacer. An upper surface of the member having the at least one positioning portion is disposed lower than the circuit board and the upper surface of the circuit board.
