Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swing chairs have a fixed swing frequency that cannot be adjusted, making it impossible to match the user's breathing rate for optimal relaxation, and the current electrically-driven designs are prone to damage from impacts.
Innovation Solution
A chair with a swing function that includes a base frame, a swing structure with a swing base frame and swing arms, and a swing driving component comprising a motor, transmission component, eccentric, universal component, and connecting device, which allows for adjustable swing frequency and improved durability through buffering mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gear and connecting rod mechanism is used to drive the swing base frame, then the swing function can be achieved, but the gear is prone to damage and product life is shortened when impacted
Solution Approach 1:
The patent introduces a buffer component as an intermediary element between the driving mechanism and the swing base frame. This buffer absorbs impact forces before they reach the gear, preventing direct transmission of harmful shocks. The buffer acts as a protective mediator that decouples the rigid connection, allowing the gear to operate without direct exposure to impact loads while still transmitting the necessary driving force for swing motion.
2Adaptability or versatility
If the swing frequency is fixed based on the swing mechanism length, then the swing function can be provided, but the swing rate cannot be adjusted to match user's breathing rate
Solution Approach 1:
The patent transforms the fixed-length swing mechanism into a dynamically adjustable system. By making the swing arm length variable rather than fixed, the system can adapt its swing characteristics in real-time. This dynamic configuration allows the swing frequency and amplitude to be adjusted according to different user needs, including matching breathing rates for relaxation, without fundamentally changing the overall mechanism structure.
Solution Approach 2:
The patent changes the physical parameters of the swing mechanism, specifically the effective length of the swing arm, to control swing frequency. By adjusting this geometric parameter, the system can achieve different swing rates without adding complex control systems. This parameter-based control method simplifies the overall device complexity while providing the needed adaptability for different user requirements.
