Solution Overview

Problem

Conventional storage battery grids face issues with mechanical strength, electric resistance, and uneven potential distribution, leading to local corrosion and short lifetimes due to the absence of frame bones connecting upper and lower frames, resulting in elongation and increased electric resistance.

Innovation Solution

A storage battery grid with a frame bone of rectangular shape, including a lug portion, a main bone extending between side portions, and obliquely extending sub-bones that branch and bend, reducing electric resistance and promoting uniform potential distribution while enhancing mechanical strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If an expanded grid without frame bone is used, then the grid structure is simple, but the grid is liable to be elongated in vertical direction and short-circuiting occurs

Engineering Contradiction:
Improvegrid structureVSAvoidshort-circuiting resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The grid is segmented into distinct functional components: frame bones (providing mechanical support and preventing elongation), lateral frames (collecting current), and radial frames (conducting current to lug portion). This segmentation allows each component to specialize in its function, resolving the contradiction between structural simplicity and short-circuiting resistance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grid structure employs a nested arrangement where radial frames extend from the lug portion through the net-like frame to the opposite side, with lateral frames connecting these radial frames. This nested configuration creates multiple current pathways while maintaining structural integrity, preventing elongation without excessive complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If an expanded grid without frame bone is used, then the manufacturing process is simple, but the net-like frame becomes serrate and current channel becomes long

Engineering Contradiction:
Improvegrid fabricationVSAvoidframe straightness
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

By dividing the grid into frame bones, lateral frames, and radial frames, the manufacturing process can focus on creating straight, precise segments that are then assembled. This segmentation allows each component to be manufactured with higher precision while maintaining overall manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame bones and lateral frames are pre-formed with precise geometries before assembly. This preliminary preparation ensures that the net-like frame maintains straightness and proper current channel geometry, achieving manufacturing precision without complicating the overall fabrication process.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the net-like frame is serrate from upper to lower frame, then the grid structure is continuous, but the current channel becomes long and electric resistance increases

Engineering Contradiction:
Improveframe continuityVSAvoidelectric resistance
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The current collection system is segmented into radial frames that provide direct pathways from the net-like frame to the lug portion, and lateral frames that connect radial frames. This segmentation creates multiple short current channels, reducing electric resistance while maintaining the continuity of the overall grid structure through the interconnected frame system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grid structure adds a lateral dimension with lateral frames connecting radial frames across the width of the grid. This dimensional addition creates parallel current pathways, reducing the length of current channels and electric resistance while preserving structural continuity through the three-dimensional frame network.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If radial frames with branch frames are used, then the current collection is improved, but the current channel becomes long due to portion apart from lug portion

Engineering Contradiction:
Improvecurrent collection efficiencyVSAvoidcurrent channel length
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The current collection system is segmented into radial frames that extend directly from the lug portion to the opposite side, providing short, direct current channels. Lateral frames then connect these radial frames, creating multiple parallel pathways. This segmentation ensures that no portion is far from the lug portion, as all current must travel through the radial frames that originate at the lug, minimizing current channel length while maintaining efficient current collection.

Inventive Principle:
Principle #1Segmentation
