Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a laser source is used for fixation member securement, then minimally invasive benefits and precision are improved, but safety risks and procedural complexity increase

Engineering Contradiction:
ImproveprecisionVSAvoidprocedural complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The laser source is designed to be selectively switchable between inactive and active configurations, allowing the system to transition between states based on procedural needs. This dynamic control enables precision when needed while reducing complexity and safety concerns when the laser is not required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameter of the laser source from inactive to active state based on procedural requirements. This parameter switching allows the same device to serve both precision laser applications and standard non-laser procedures, reducing overall procedural complexity.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If strict protective measures are implemented for laser safety, then safety risks are reduced, but procedural complexity increases

Engineering Contradiction:
Improvesafety risksVSAvoidprocedural complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The selective switchability of the laser source allows the system to dynamically adjust safety measures based on whether the laser is active. When inactive, fewer protective measures are needed, simplifying the procedure. When active, appropriate safety protocols are engaged, ensuring safety without unnecessary complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent extracts the laser emission function from the always-on state, placing it under selective control. This separation allows the system to operate in a simplified non-laser mode when possible, removing the need for continuous laser safety protocols while maintaining the capability when precision is required.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If laser emission is continuously available, then procedural efficiency is improved, but safety risks increase

Engineering Contradiction:
Improveprocedural efficiencyVSAvoidsafety risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The laser source transitions from a continuous emission state to a selectively activated state. This dynamic control maintains procedural efficiency by enabling laser use when needed while reducing safety risks by eliminating continuous emission and associated hazards during non-laser portions of the procedure.

Inventive Principle:
Principle #15Dynamics

AI summary

A laser device having a proximal end and a distal end spaced from the proximal end, the distal end configured to receive a fixation member to be affixed to a target surgical site. The laser device includes a laser source supported by the laser device body and capable of emitting a laser beam to the distal end, wherein the laser source is responsive to at least one input so as to selectively switch between an inactive configuration whereby the laser source does not emit the laser beam, and an active configuration whereby the laser source emits the laser beam.
