Stacked Circuit Member Layout for Thin Electrical Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacked circuit devices with multiple circuit members tend to have a large height due to the inclusion of various components such as capacitors and IC chips, which limits their compactness and versatility.
Innovation Solution
The device comprises a first, second, and third circuit member, each with a main portion and an integrated-electrode portion on a flexible board, allowing for electrical connections between the main portions without the need for direct stacking of the main bodies, thereby reducing the overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple circuit members are stacked with insulation sheets and components, then electrical connection between circuit members is achieved, but the height of the device increases
Solution Approach 1:
The patent transitions from vertical stacking of complete circuit members to horizontal arrangement of separated main portions, with electrodes extending vertically to establish connections. This dimensional reorganization allows electrical connectivity without the cumulative height of stacked components.
Solution Approach 2:
The circuit members are segmented into separate main portions that are horizontally arranged rather than vertically stacked. Each main portion contains its functional components, and connection is achieved through separate electrode structures rather than direct stacking, thereby reducing overall device height.
2Adaptability or versatility
If various components such as capacitors and IC chips are included in circuit members, then circuit functionality is achieved, but the device height increases
Solution Approach 1:
Components are segregated into their respective main portions rather than being vertically stacked. Each main portion maintains its functional integrity with capacitors, IC chips, and other components housed within, while the horizontal arrangement prevents height accumulation.
Solution Approach 2:
Electrodes serve as intermediary connection elements that extend from the horizontally arranged main portions to establish electrical connections. This intermediary structure enables functionality without requiring vertical stacking of the component-containing bodies.
3Length of stationary object
If circuit members are directly stacked to reduce height, then compactness is improved, but manufacturing complexity and connection reliability deteriorate
Solution Approach 1:
The design segments the circuit into independently manufacturable main portions that are arranged horizontally. Each portion can be manufactured separately with standard processes, and the electrode connections are established through controlled extensions rather than complex through-hole drilling and soldering required in direct stacking.
Solution Approach 2:
By arranging main portions horizontally and extending electrodes vertically, the patent simplifies the manufacturing process. This dimensional approach allows for easier alignment and connection compared to vertical stacking, which requires precise through-hole alignment and soldering across multiple layers.

AI summary
A device comprises a first circuit member, a second circuit member and a third circuit member. The first circuit member comprises a first body for performing the function of the first circuit member and a first flexible board formed with a first integrated-electrode portion including first electrodes. The second circuit member comprises a second body for performing the function of the second circuit member and a second flexible board formed with a second integrated-electrode portion including second electrodes. The third circuit member comprises a third body for performing the function of the third circuit member and a third flexible board formed with a third integrated-electrode portion including third electrodes. The first integrated-electrode portion, the second integrated-electrode portion and the third integrated-electrode portion lie over each other in an upper-lower direction. The first body, second body and the third body are apart from each other when seen along the upper-lower direction.
