Angled Skid Sections for Spotlight Cable Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing skid devices for spotlights often lead to damage of the spotlight cable due to pinching between the bow arms and skids during pivoting or adjustment of the spotlight's inclination, posing risks of short circuits and damage to the cable or the spotlight itself.
Innovation Solution
The skid device features angled sections between the end sections of the skids, allowing sufficient play for the spotlight cable to pass through, ensuring a safe and reliable cable layout independent of the bow position, with optional oblique or rectangular angling transitions and cross tubes for enhanced stability and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the skids are spaced closely to save space, then the compactness of the spotlight is improved, but the cable may be pinched between the bow arms and skids during pivoting
Solution Approach 1:
The skid device is segmented into multiple skids (at least three skids) arranged in a specific pattern. By dividing the support structure into separate skid elements rather than a single solid base, the design creates defined pathways for the cable while maintaining compact overall dimensions. The skids are positioned to form channels that guide the cable away from pinch zones.
Solution Approach 2:
The skids act as intermediary elements between the bow arms and the underlying surface, creating a controlled pathway for the cable. The specific arrangement of skids provides a mediator structure that separates the cable path from the bow arm movement zone, preventing direct contact and pinching while maintaining space efficiency.
2Area of moving object
If the bow is positioned close to the skids to reduce lateral projection, then the spotlight width is reduced, but the cable cannot be led through safely without additional manipulations
Solution Approach 1:
The skid device exhibits local quality variations in its structure, with specific skids positioned to create localized cable pathways. The non-uniform arrangement of skids (with at least one skid offset from the central longitudinal axis) creates specific zones of clearance for cable passage while maintaining minimal overall lateral projection. This localized structural differentiation enables safe cable laying without increasing the spotlight's overall width.
3Device complexity
If the spotlight cable is led close to the housing to minimize cable management complexity, then the cable routing is simplified, but the cable is at risk of being pinched during inclination adjustment
Solution Approach 1:
The skid device is designed with pre-established cable pathways formed by the skid arrangement. The skids are positioned in advance to create defined channels that guide the cable from the cable bushing to the rear of the spotlight housing. This preliminary structural arrangement eliminates the need for complex cable management during operation and prevents pinching by maintaining permanent clearance zones.

AI summary
The invention relates to a skid device (6) for spotlights with skids (7, 8), which extend essentially parallel to the optical axis of the spotlight, and cross members (11, 12), which connect the skids (7, 8) to one another and which serve to hold a bottom section of the spotlight housing (3). The invention provides that at least one skid (7, 8) has a section (73 to 75, 83 to 85) situated at an angle to the center longitudinal axis (M) of the spotlight housing (1, 3).
