Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high initial setup cost of lithium-ion batteries inhibits their adoption in power systems, such as UPSs, despite their advantages over lead-acid batteries, and there is a need for systems compatible with both types.
Innovation Solution
A power system mechanism featuring a lever bar that moves between positions to enable or block specific types of battery cartridges and connectors, ensuring compatibility with either lithium-ion or lead-acid batteries, using stopper elements and spring biasing to prevent incorrect connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power system is designed to support multiple battery types (lithium-ion and lead-acid), then battery type compatibility is improved, but device complexity increases due to the need for switchable connectors and blocking mechanisms
Solution Approach 1:
The patent implements a dynamic switching mechanism where a lever bar can physically reposition to connect different battery type connectors (lithium-ion or lead-acid) to the power system. This dynamic reconfiguration allows a single power system to adapt to multiple battery types without requiring multiple fixed connector sets, thereby improving versatility while managing complexity through a unified switching structure.
Solution Approach 2:
The power system incorporates a universal connector interface that can accommodate both lithium-ion and lead-acid battery types through a single multi-functional connector assembly. The lever bar mechanism enables this universal interface to switch between different connector configurations, allowing one connector system to serve multiple battery type functions rather than requiring separate dedicated connectors for each battery type.
2Ease of operation
If a lever bar mechanism is introduced to switch between battery types, then ease of operation is improved, but device complexity increases due to additional moving parts and blocking elements
Solution Approach 1:
The lever bar mechanism is designed to be manually operated by the user to select the desired battery type, eliminating the need for complex automated detection and switching systems. The user directly controls the connector configuration by moving the lever bar to the appropriate position, which simplifies the control logic while maintaining ease of operation. The mechanism essentially serves itself through direct user manipulation without requiring additional sensors, motors, or control circuits.
Solution Approach 2:
The connector switching mechanism is segmented into distinct positional states (lithium-ion position and lead-acid position) that are physically separated and clearly defined. The lever bar moves between these discrete segments, each corresponding to a specific battery type configuration. This segmentation provides clear visual and tactile feedback to the user, making operation intuitive while keeping the mechanism relatively simple through well-defined positional states rather than continuous adjustment.
3Reliability
If stopper elements are added to prevent incorrect connections, then reliability is improved, but device complexity increases due to additional blocking components
Solution Approach 1:
The stopper elements are pre-positioned on the lever bar mechanism to physically block access to incorrect connector types before a user can attempt to connect them. When the lever bar is in the lithium-ion position, stoppers prevent lead-acid connectors from being inserted, and vice versa. This preliminary blocking action occurs automatically as part of the lever bar positioning, preventing incorrect connections before they can happen rather than relying on post-connection detection or correction mechanisms.

AI summary
A power system includes a lever bar configured to move between a first position and a second position. In the first position, the lever bar is configured to enable the power system to mate with a first type of replacement battery cartridge, mate with a first type of external battery connector, block a second type of replacement battery cartridge, and block a second type of external battery connector. In the second position, the lever bar is configured to enable the power system to mate with the second type of replacement battery cartridge, mate with the second type of external battery connector, block the first type of replacement battery cartridge, and block the first type of external battery connector.
