Work Machine Travel Control by Revolving Angle and Object Direction

The patent applies local quality by differentiating the restriction application based on spatial location. Instead of uniformly restricting all operations when an object is detected, the system selectively restricts only those operations that would move the work machine toward the detection target object. This localized approach maintains safety for critical directions while preserving operator freedom in safe directions, thereby resolving the contradiction between safety and operator convenience.

The patent implements dynamics by making the restriction state adaptive rather than static. The restriction is dynamically adjusted based on the real-time position of the detection target object relative to the work machine. As the object's position changes, the restricted operation directions change accordingly, allowing the system to maintain optimal safety coverage while minimizing unnecessary operational restrictions.

This localized approach maintains safety for critical directions while preserving operator freedom in safe directions, thereby resolving the contradiction between safety and operator convenience.

The patent applies partial action by implementing only the necessary portion of operation restriction rather than complete restriction. Specifically, it restricts only the operations that lead toward the detection target object while allowing other operations to proceed normally. This partial restriction approach provides sufficient collision avoidance protection without the excessive action of completely halting all operations, thus maintaining operational efficiency.

The patent applies universality by making the detecting device multi-functional. By disposing the detecting device on the revolving portion, it simultaneously performs detection in multiple directions as the revolving portion rotates, eliminating the need for multiple separate detecting devices positioned at different locations. This multi-functional approach expands detection coverage while avoiding the complexity increase that would result from adding multiple independent detection systems.

The patent applies merging by combining the detection function with the revolving portion structure. Rather than adding a separate, independent detection system, the detecting device is integrated onto the existing revolving portion, which already has rotational movement capability. This merging approach leverages the existing structural motion to achieve expanded detection coverage without proportionally increasing system complexity.
