Imaging Device Harness Cover Rotating Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face issues with load input to wiring when the camera rotates, leading to sliding and potential damage, and struggle with compactness due to harness positioning.
Innovation Solution
An imaging device design featuring a supporting body with an insertion hole that allows wiring to be inserted and covered by a rotating covering body, which integrates with the imaging unit, preventing load input and optimizing compactness through inclined and circumferentially arranged wiring paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the gap between the upper end of the shaft and the upper wall of the cover member is made smaller to achieve compactness, then the device becomes more compact in the up-down direction, but the harness is pressed at the upper end of the shaft and slides against it, causing load to be input to the harness when the camera rotates
Solution Approach 1:
The patent introduces a shaft upper end cover as an intermediary component between the shaft and the cover member. This cover member covers the shaft upper end and provides a dedicated wiring passage, preventing the harness from directly contacting and sliding against the shaft upper end. The intermediary structure eliminates the harmful sliding action while maintaining compact dimensions.
2Ease of operation
If the shaft is made tube-shaped to allow harness insertion, then the harness can be routed through the shaft, but the harness slides against the shaft when the camera rotates, inputting load to the harness
Solution Approach 1:
The shaft upper end cover acts as a mediator that separates the harness from the rotating shaft. The cover member remains stationary while the shaft rotates, and the wiring passage in the cover member guides the harness without allowing it to slide against the shaft, thus protecting the harness from load and wear.
Solution Approach 2:
The patent divides the shaft upper end region into separate functional zones: the rotating shaft, the stationary cover member, and the wiring passage. This segmentation allows the harness to be routed through a dedicated stationary passage rather than moving with the rotating shaft, eliminating sliding friction and load on the harness.
3Volume of moving object
If the wiring passage in the cover member is made inclined, then the projection of the wiring in the up-down direction is minimized achieving compactness, but the wiring path becomes more complex
Solution Approach 1:
The patent resolves the wiring routing challenge by transitioning from a vertical up-down arrangement to an inclined arrangement in the radial direction. The wiring passage is configured to extend radially outward from the shaft center, allowing the harness to exit the rotating region at a reduced up-down projection while managing the wiring path through radial rather than vertical orientation.

AI summary
In an imaging device 10, a bracket 22 and a camera are capable of rotating with respect to a base 12, and harnesses 52 are routed inside an inner supporting tube 16 of the base 12. A covering frame 40 of a harness cover 38 covers an upper end portion of the inner supporting tube 16, the harness 52 is abutted on the covering frame 40, and the covering frame 40 is capable of rotating integrally with the bracket 22. This enables the harnesses 52 to be suppressed from sliding on the covering frame 40 and enables load input to the harnesses 52 to be suppressed when the bracket 22 is rotated, even though the harness 52 is press-contacted to the covering frame 40.
