Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional weight loss methods (diets, medications, surgery) are used, then weight loss is achieved, but muscle mass is lost and skin elasticity deteriorates

Engineering Contradiction:
Improveweight lossVSAvoidmuscle mass
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The electrostimulation device segments the weight loss process into two independent phases: fat loss through caloric restriction and muscle maintenance through electrical stimulation. This allows simultaneous pursuit of weight loss while preventing muscle atrophy, resolving the contradiction between reducing body weight and maintaining muscle mass.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Electrical stimulation acts as an intermediary mechanism that bridges the gap between caloric restriction and muscle preservation. The electrical impulses directly stimulate muscle fibers to contract and maintain strength without requiring mechanical exercise, thereby protecting muscle mass during weight loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If intensive physical exercise is performed to maintain muscle mass, then muscle strength is improved, but device complexity and cost increase

Engineering Contradiction:
Improvemuscle massVSAvoidtechnological complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The device replaces complex mechanical exercise systems with a simpler electrical stimulation system. Instead of requiring gyms, weights, and mechanical exercise equipment, the invention uses electrical impulses delivered through electrodes to directly stimulate muscle contraction, significantly reducing device complexity while maintaining muscle mass.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If conventional electrodes are used, then electrostimulation is provided, but adaptability to different body sizes is poor

Engineering Contradiction:
Improveelectrostimulation deliveryVSAvoidadaptability to body sizes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The electrode system employs dynamic, flexible materials that can adapt to different body contours and sizes. The electrodes are designed with elastic properties allowing them to conform to various anatomical shapes, enabling the same device to effectively treat users across a wide range of body types and sizes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device allows adjustment of electrical stimulation parameters (intensity, frequency, pulse duration) to accommodate different body sizes and muscle masses. By changing these electrical parameters, the system optimizes its effectiveness for individual users regardless of their physical dimensions.

Inventive Principle:
Principle #35Parameter changes
