Housing Baffle Mechanism Prevents Simultaneous Charging and Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rechargeable physiotherapy devices can be damaged by charging during use, leading to malfunctions and reduced service life, particularly among elderly or pain-stricken patients who may ignore safety instructions.
Innovation Solution
A housing apparatus with baffle plates and springs that prevent simultaneous charging and use by sliding mechanisms, ensuring the charging port is accessible only when the output interfaces are blocked, and vice versa, using handles to counteract spring forces for safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If charging port and output interfaces are simultaneously accessible, then device versatility is improved, but device reliability deteriorates due to risk of simultaneous charging and use
Solution Approach 1:
The baffle plate is designed to be movable rather than fixed, allowing it to dynamically block or expose the charging port based on the state of the output interfaces. When output interfaces are in use, the baffle plate automatically moves to block the charging port, and vice versa. This dynamic mechanism ensures that charging and use cannot occur simultaneously, resolving the reliability issue while maintaining versatility when needed.
Solution Approach 2:
The baffle plate acts as an intermediary element between the charging port and output interfaces. It physically mediates access to these ports, ensuring that when one set is accessible, the other is blocked. This intermediary mechanism prevents the harmful state of simultaneous charging and use while still allowing both functions to be used separately, thus maintaining device versatility without compromising reliability.
2Reliability
If safety instructions are provided to prevent simultaneous charging and use, then device reliability is improved, but ease of operation deteriorates due to user complexity
Solution Approach 1:
The device performs safety management automatically through the baffle plate mechanism without requiring user intervention or attention to safety instructions. The system self-regulates by automatically blocking the charging port when output interfaces are in use, and vice versa. This eliminates the need for users to read or follow safety instructions, making the device equally easy to operate for all users including elderly or pain-stricken patients while maintaining high reliability.
Solution Approach 2:
The patent replaces the mechanical approach of providing safety instructions (manuals, labels) with an automatic mechanical mechanism (baffle plate system). Instead of relying on users to understand and follow instructions, the physical mechanism automatically enforces safe operation. This substitution transforms safety from a user-dependent process to a system-enforced process, improving both reliability and ease of operation.
3Reliability
If baffle plate mechanism is added to prevent simultaneous charging and use, then device reliability is improved, but device complexity increases
Solution Approach 1:
The housing is segmented into functional zones using the baffle plate that can independently control access to different ports. The baffle plate itself is a simple segmented component that divides the housing interior, creating separate accessible regions. This segmentation approach allows the complex safety function to be achieved through a relatively simple structural division rather than a complex control system.
Solution Approach 2:
The safety control function is extracted from the main device body and implemented as a separate, independent baffle plate mechanism. This extracted component handles the complexity of preventing simultaneous charging and use, while the main device remains simple. The baffle plate is a standalone element that can be added to existing devices without fundamentally redesigning the entire system, thus managing complexity effectively.
