Conventional solutions for supporting safety wires on buildings are overly complex and hinder the smooth passage of traveler devices, increasing the risk of getting caught and complicating the user's movement.

Innovation Solution

An apparatus featuring a pivotally attached wheel with a unique radial extension configuration that forms recesses to guide the traveler device and safety line past the support, ensuring unobstructed movement along the wire by reducing the risk of entanglement and simplifying the bypass process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wire support solutions are used, then the wire can be supported on the building structure, but the traveler device and safety line may get caught by the support, complicating user movement

Engineering Contradiction:

ImprovesafetyVSAvoidmovement along wire

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

A wheel is introduced as an intermediary component between the wire support and the traveler device. The wheel rotates to guide the traveler device and safety line past the support structure, preventing entanglement while maintaining wire support functionality. The wheel acts as a mediator that resolves the conflict between structural support and smooth movement.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The wheel is made rotatable about an axis of rotation, transforming a static support structure into a dynamic one. This dynamic element adapts to the passage of the traveler device, automatically adjusting its position to guide the device past the support without obstruction, thereby ensuring continuous safe movement along the wire.

Inventive Principle:

Principle #15Dynamics

2Reliability

If conventional wire support solutions are used, then the wire can be supported, but the structure becomes overly complex

Engineering Contradiction:

Improvewire supportVSAvoidsupport structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The support structure is segmented into distinct functional components: a support body for anchoring to the building, a rotatable wheel for guiding the traveler device, and a seat for supporting the wire. This segmentation allows each component to perform its specific function efficiently, reducing overall complexity while maintaining reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wheel serves multiple functions simultaneously: it supports the wire through the seat, guides the traveler device past the support, and prevents entanglement of the safety line. This multi-functionality reduces the need for additional separate components, simplifying the overall structure while ensuring reliable wire support.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the wheel has deep recesses to hold traveler device, then guidance is improved, but the radial extension increases causing entanglement risk

Engineering Contradiction:

Improveguidance of traveler deviceVSAvoidentanglement risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The radial extension parameter of the wheel is carefully controlled and optimized. The first radial extension (from center to outer boundary of center section) exceeds the second radial extension (from outer boundary of center section to peak of outer section), creating shallow recesses that provide adequate guidance while minimizing the risk of entanglement. This parameter optimization balances guidance effectiveness with safety.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The wheel features localized structural variations: a center section with specific radial extension and outer sections with peaks forming shallow recesses. Each local region is designed with specific qualities appropriate to its function - the center section provides structural stability while the outer sections with controlled radial extensions provide guidance without excessive depth, reducing entanglement risk.

Inventive Principle:

Principle #3Local quality
