Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single electrode pair is used to apply electric signals to the brain, then the device complexity is reduced, but the amount of information transmitted through the corpus callosum is insufficient to effectively improve brain dysfunction

Engineering Contradiction:

Improveamount of information through corpus callosumVSAvoidelectrode configuration

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The invention divides the electrode system into two separate electrode pairs: a first electrode pair applied to the right hemisphere and a second electrode pair applied to the left hemisphere. This segmentation allows independent stimulation of each hemisphere, thereby increasing the amount of information transmitted through the corpus callosum while maintaining manageable device complexity through modular electrode design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention applies different electric signal characteristics to each electrode pair based on local needs. The first electrode pair receives a first electric signal with specific parameters, while the second electrode pair receives a second electric signal with different parameters. This local differentiation optimizes information transmission through the corpus callosum by tailoring stimulation to each hemisphere's specific requirements.

Inventive Principle:

Principle #3Local quality

2Loss of energy

If the same electric signal is applied to both electrode pairs, then the ease of operation is improved, but the metabolic stimulation of nerve fibers in the corpus callosum is insufficient

Engineering Contradiction:

Solution Approach 2:

The invention employs periodic electric signals with varying parameters applied alternately or simultaneously to the two electrode pairs. This periodic stimulation with different characteristics creates metabolic activity in the corpus callosum nerve fibers, enhancing energy utilization and promoting neural recovery while maintaining systematic operation through programmed signal delivery.

Inventive Principle:
