Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices lack an interchangeable accumulator unit with enhanced charging capabilities, as current designs do not facilitate efficient charging and power supply through multiple contact arrangements, limiting flexibility and reliability.
Innovation Solution
An interchangeable accumulator unit with a housing containing a lithium accumulator cell, a charging circuit for controlling the charging process, and two charging contact units on different sides of the housing, allowing charging via multiple contact arrangements, including a ground closure, positive connection for supply voltage, and a status contact for charging state indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single charging contact unit is provided in the housing, then the charging circuit can be simplified, but the accumulator unit lacks charging flexibility and cannot be charged in different orientations
Solution Approach 1:
The housing is equipped with multiple charging contact units (first and second charging contact units) positioned on different sides, enabling the accumulator unit to be charged in various orientations and configurations. This multi-functional design allows the same charging circuit to serve multiple charging scenarios, achieving versatility without proportionally increasing complexity.
Solution Approach 2:
Instead of adding complexity to a single charging contact unit, the invention distributes charging contact units across different spatial dimensions (different sides of the housing). This dimensional approach allows the accumulator to be charged from multiple orientations, transforming a single-point charging limitation into a multi-point spatial solution.
2Adaptability or versatility
If the accumulator unit is designed for interchangeability only, then replacement of defective units is enabled, but charging capabilities and power supply flexibility are limited
Solution Approach 1:
The charging contact unit is segmented into multiple independent contacts (ground closure, positive connection for charging voltage, positive connection for supply voltage, status contact). This segmentation allows each contact to serve a specific function while collectively providing versatile charging and power supply capabilities through a single standardized interface.
Solution Approach 2:
The accumulator unit design allows dynamic adaptation to different charging scenarios through its multiple charging contact units positioned on different sides. The system can dynamically select which charging contact unit to use based on the charging orientation and requirements, providing flexibility without complicating the user operation.
3Adaptability or versatility
If multiple charging contact units are provided on different sides of the housing, then charging flexibility and interchangeability are improved, but the device structure becomes more complex
Solution Approach 1:
Multiple charging contact units are merged into a standardized housing interface design where all contact units share the same electrical and mechanical specifications. This merging approach allows the housing structure to accommodate multiple charging contact units without proportionally increasing complexity, as they can be manufactured and integrated using standardized processes.
