Camera Track Dolly Steering Linkage for Off-Track Directional Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track dollies lack directional control when not on a track, are often bulky and heavy, restrict camera or accessory mounting, and are expensive or complex, limiting their versatility and ease of use.
Innovation Solution
A track dolly with a steering mechanism, adjustable linkage members, and rotatable wheels that allow for enhanced directional control on the ground, accommodating various camera and accessory mounts, and featuring a handle to adjust wheel positions for improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a track dolly is designed without a steering mechanism, then the structure is simpler and lighter, but directional control when removed from a track is lost
Solution Approach 1:
The steering mechanism is segmented into independent components: a handle assembly that rotates independently, linkage members that connect the handle to individual wheels, and a plate that serves as the base structure. This segmentation allows each component to perform its specific function while maintaining overall system simplicity.
Solution Approach 2:
The steering mechanism employs dynamic elements including a rotatable handle that can be maneuvered to different positions, linkage members that transmit motion dynamically, and wheels that can be rotatably adjusted relative to the plate. This dynamic design enables directional control without requiring a complex fixed steering structure.
2Adaptability or versatility
If camera mounting options are restricted to the center of the dolly, then the structure is simpler, but versatility in mounting different camera and accessory configurations is limited
Solution Approach 1:
The plate serves multiple functions: it acts as the base structure for the dolly, provides mounting surfaces for cameras and accessories at various positions, and serves as the attachment point for linkage members. The rails coupled to the plate also provide both structural support and mounting capability, enabling universal accommodation of different camera and accessory configurations.
Solution Approach 2:
Mounting options are extended from a single center point to multiple dimensions by coupling rails to the plate at different locations. This allows cameras and accessories to be mounted at various positions along the rails and on different surfaces of the plate, transforming a one-dimensional mounting constraint into a multi-dimensional mounting system.
3Stability of the object's composition
If the dolly is designed to be bulky and heavy for stability, then stability is improved, but ease of maneuverability during use is reduced
Solution Approach 1:
The dolly employs dynamic wheel adjustment capability where the wheels can be rotatably adjusted relative to the plate through the linkage members. This allows the wheels to be optimized for different operating conditions - providing stability when needed and ease of maneuverability when moved, resolving the contradiction between fixed stability and dynamic maneuverability.
Solution Approach 2:
The steering mechanism allows changes in operational parameters by enabling the handle to be maneuvered to different positions, which through the linkage members adjusts the orientation of the wheels. This parameter adjustment capability allows the dolly to transition between stable positioning and easy maneuvering as needed.
4Ease of operation
If a steering system controls all wheels to enhance directional control, then directional control is improved, but the number and type of accessories that can be attached is limited
Solution Approach 1:
The steering control is segmented to allow selective adjustment of wheels through linkage members connected to a common handle. This segmented approach provides directional control through the steering mechanism while leaving other portions of the plate and rails available for accessory attachment, avoiding the limitation of a fully integrated steering system that would occupy all mounting space.

AI summary
A track dolly to mount a camera and accessories thereon is provided. The track dolly includes a steering mechanism to enhance directional control of the dolly when in motion. The track dolly includes a plate, at least one rail coupled to the plate and designed to permit attachment of the camera or accessories thereto, a plurality of wheels rotatably mounted to the plate, a handle rotatably mounted to the plate, and a plurality of linkage members adjustably mounted to the bottom surface of the plate and operably connected to the handle. The linkage members are operably connected to any number of the plurality of wheels. The handle is maneuvered to permit the plurality of linkage members to rotatably adjust any number of the plurality of wheels relative to the plate, thereby adjusting the directional control of the dolly.
