Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery testers are cumbersome and inefficient, requiring operators to frequently return to the main unit to change settings or view results, and the shared electrical circuit in enhanced test leads can interfere with measurement accuracy.
Innovation Solution
A wireless handle for battery testers that uses wireless communication (such as RF, Bluetooth, Wi-Fi, or ZIGBEE) to exchange information with the main body, featuring a separate power supply and distinct circuits for input and output functions, allowing for one-handed operation and reducing interference with measurement signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display, buttons, and test terminal share a common electrical circuit in the test lead, then the test lead can exchange information with the main body, but the test lead becomes large in size and has complicated circuit structure
Solution Approach 1:
The patent divides the test lead into two independent parts: a simple test terminal for measurement and a separate wireless handle for information exchange. The test terminal only contains the minimal circuit needed for electrical connection, while the wireless handle contains the display, buttons, and wireless communication module. This segmentation eliminates the need for a complex shared circuit in the test lead.
Solution Approach 2:
The patent replaces the wired electrical circuit connection for information exchange with wireless communication technology. The wireless handle uses wireless signals (such as radio frequency) to communicate with the main body, substituting the mechanical/electrical circuit connection with a field-based communication system, thereby simplifying the test lead's circuit structure.
2Adaptability or versatility
If the wire communication uses a signal frequency close to the current flowing through the testing circuit, then information can be exchanged, but the measurement accuracy is reduced due to interference
Solution Approach 1:
The patent replaces wired electrical signal communication with wireless communication technology. The wireless handle uses radio frequency signals to exchange information with the main body, substituting the electrical circuit-based communication that caused interference with a electromagnetic field-based communication system operating at different frequencies, thereby eliminating measurement interference.
Solution Approach 2:
The wireless handle acts as an intermediary device between the operator and the main body. It receives wireless signals from the main body, processes them locally (displaying results and accepting input), and communicates bidirectionally using wireless technology, thereby mediating the interaction without requiring direct electrical connection that would cause interference.
3Stability of the object's composition
If the main body is placed in a fixed location, then it remains stable, but the operator must return to it frequently to change settings or view results, reducing efficiency
Solution Approach 1:
The wireless handle serves as a mobile intermediary that bridges the operator and the fixed main body. It receives control commands from the operator and transmits them wirelessly to the main body, and simultaneously receives measurement results from the main body and displays them locally. This allows the operator to control the main body and view results at any location within wireless range, eliminating the need to return to the main body and improving testing efficiency.
Solution Approach 2:
The patent replaces the physical requirement of being at the main body location with wireless communication technology. The wireless handle enables remote operation and monitoring through wireless signals, substituting the mechanical constraint of physical presence with a field-based communication system, thereby improving operational flexibility and efficiency.
4Ease of operation
If the operator holds test leads in both hands to contact battery terminals, then measurement can be performed, but the operator cannot simultaneously operate the main body or check results conveniently
Solution Approach 1:
The wireless handle acts as a mobile information interface that the operator can hold in one hand while performing measurements. It displays measurement results and accepts control inputs locally, serving as an intermediary between the operator's hands (holding test leads) and the main body operations. This allows the operator to simultaneously perform measurement operations and interact with the system, improving efficiency.
