Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a patient support system provides stable support, then patient comfort and safety are improved, but core muscle engagement and exercise effectiveness deteriorate

Engineering Contradiction:
Improvepatient safetyVSAvoidcore muscle engagement
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The support surface is transformed from a static, stable structure to a dynamic, unstable one through the incorporation of an instability apparatus. The apparatus includes a platform that can tilt or shift position, creating controlled instability that requires continuous core muscle activation to maintain balance and proper posture during exercise activities.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The instability apparatus changes the physical parameters of the support surface by introducing variable tilt angles and positional shifts. These parameter changes create an unstable environment that challenges the patient's balance and core stability, thereby enhancing muscle engagement without compromising safety through controlled design limits.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If an instability apparatus is added to the patient support system, then core muscle engagement is improved, but device complexity increases

Engineering Contradiction:
Improvecore muscle engagementVSAvoidsystem structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The instability apparatus is nested within the existing patient support system structure. The tilting platform is integrated into the seat or support surface assembly, allowing the instability function to be incorporated without requiring a completely separate system. This nesting approach minimizes additional complexity while achieving the desired core engagement effect.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If the support surface is made unstable to engage core muscles, then exercise effectiveness is improved, but patient stability and comfort deteriorate

Engineering Contradiction:
Improveexercise effectivenessVSAvoidsupport surface stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The instability is achieved through controlled parameter changes in the support surface tilt angle and position. By carefully adjusting these parameters within safe limits, the system creates enough instability to engage core muscles while maintaining sufficient stability to ensure patient comfort and safety during exercise activities.

Inventive Principle:
Principle #35Parameter changes
