Vibration Capsule Coaxial Alignment via Segmented PCBs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vibration capsules is disrupted due to tilting caused by variations in the height of electronic devices, leading to misalignment between the control assembly and the battery assembly, which decreases the yield rate.
Innovation Solution
The vibration capsule design includes PCBs at both ends of the battery assembly connected by a flexible connecting structure, ensuring coaxial alignment and preventing tilting, with electronic devices arranged on only one side of each PCB to facilitate assembly and reduce insulation material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electronic devices are affixed by insulation sheets only, then assembly is simple, but tilting occurs and coaxiality cannot be ensured
Solution Approach 1:
A PCB supporting plate is introduced as an intermediary component between the insulation sheet and the electronic devices. This plate provides a rigid, flat surface that ensures precise positioning and coaxial alignment, while still allowing for simple assembly through the insulation sheet attachment method.
2Manufacturing precision
If PCBs are placed at both ends of battery assembly, then coaxial alignment is ensured, but assembly complexity increases
Solution Approach 1:
The control assembly is segmented into multiple PCBs positioned at different locations (both ends of the battery assembly), with each PCB independently supporting electronic devices. This segmentation allows for better distribution of components and ensures coaxial alignment without requiring a single complex assembly structure.
3Loss of substance
If electronic devices are arranged on one side of PCB, then insulation material is reduced, but space utilization may be affected
Solution Approach 1:
Electronic devices are strategically arranged on only one side of the PCB where space is available and does not interfere with the battery assembly or other critical components. This local arrangement optimizes the use of available space while minimizing insulation material requirements, as insulation is only needed where electronic devices are present.

AI summary
The present invention discloses a vibration capsule, including: an enclosure, a vibration motor, a battery assembly, and a control assembly. The vibration motor, the battery assembly and the control assembly are disposed within the enclosure, the vibration motor and the battery assembly are electrically connected to the control assembly. The control assembly includes a first PCB and a second PCB, disposed at opposite ends of the battery assembly, a connecting structure that connects the first PCB and the second PCB, and a plurality of electronic devices disposed on one side of the first PCB away from the battery assembly, and/or on one side of the second PCB away from the battery assembly. The present invention achieves that there is no relative tilt between the control assembly and the battery assembly, ensuring coaxial alignment between the control assembly and the battery assembly.
