Battery Wiring Module Covering With Dual-Side Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face difficulties in distinguishing between the positive and negative electrode sides when attaching a battery wiring module to a secondary battery and its housing, particularly when the covering is open or closed, leading to potential errors in attachment and detachment operations.
Innovation Solution
The battery wiring module incorporates information indicators on both the top and back faces of the covering, with recessed and protruding shapes respectively, allowing easy recognition of operational information regardless of the covering's state, and is designed with a hinge for openable and closable functionality to facilitate error-free operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the covering is made with a simple flat structure, then the manufacturing is easy and material usage is low, but the operator cannot easily discern operational information when the covering is open or closed
Solution Approach 1:
The patent applies dimensionality change by forming information indicators that protrude from one surface of the covering and correspond to recesses on the opposite surface. This three-dimensional configuration allows operational information to be visible and tactile from either side of the covering, solving the problem of information visibility without requiring complex additional components.
Solution Approach 2:
The patent uses visual differentiation through color or contrast variations in the information indicators. The indicators are formed with different colors or contrast levels compared to the covering body, making them easily distinguishable and visible to operators regardless of whether the covering is open or closed.
2Ease of operation
If information indicators are provided only on one face of the covering, then the structure remains simple, but the operator cannot recognize operational information from either side when the covering state changes
Solution Approach 1:
The information indicators serve multiple functions simultaneously: they provide visual information about operational status, maintain structural integrity of the covering, and enable recognition from both sides. The indicators are integrated into the covering structure itself rather than being separate components, allowing the same structure to fulfill multiple purposes.
Solution Approach 2:
By extending information indicators in the thickness direction of the covering with protrusions on one surface and corresponding recesses on the other, the patent enables operational information to be accessed from either side without adding complex multi-layer structures.
3Reliability
If the covering structure is simplified without information indicators, then manufacturing is easier and material usage is reduced, but operational errors increase due to poor visibility of operational information
Solution Approach 1:
The information indicators are pre-formed as integral parts of the covering structure during manufacturing, rather than being added as separate components afterward. This preliminary integration ensures that operational information is always available without requiring additional assembly steps or complex post-manufacturing processes.

AI summary
A battery wiring module that allows an operator to easily perform operations. A battery wiring module includes: bus bars and electrical wires, which are to be electrically connected to an on-board secondary battery; a housing that is to be attached to the secondary battery, and includes bus bar housing portions and an electrical wire housing portion that house the bus bars and the electrical wires; and a second lid for closing openings of the bus bar housing portions. Information indicators that indicate operational information (“+”, “−”) are provided on the top and back faces of the second lid.
