Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging units face challenges with high traveling resistance due to brakes and friction, especially when heavy or with insufficient driving force, making manual or electric travel difficult.
Innovation Solution
An electric traveling unit that combines with the imaging unit, reducing traveling resistance by generating a vertical load to lift the unit partially off the ground, using a load generating mechanism and narrower wheel spacing, and enabling electric travel even with high resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brake is applied to prevent inadvertent movement, then safety is improved, but traveling resistance increases making electric pulling impossible
Solution Approach 1:
The patent introduces a brake release mechanism as an intermediary device that mediates between the brake system and the electric traveling system. When electric traveling is required, the brake release mechanism automatically releases the brake, allowing the electric traveling unit to pull the imaging unit without excessive resistance. This resolves the contradiction by temporarily disabling the brake during electric travel while maintaining it for safety during manual operation.
Solution Approach 2:
The brake state is made dynamic rather than static. The system automatically switches between brake applied and brake released states based on the operating mode (manual vs. electric traveling). This dynamic adjustment allows the system to have high traveling resistance when safety is needed and low traveling resistance when electric pulling is required, resolving the fundamental contradiction between these two requirements.
2Stability of the object's composition
If the imaging unit is heavy, then stability is improved, but traveling resistance increases making electric travel difficult
Solution Approach 1:
The patent replaces manual mechanical pulling with an electric traveling system that uses motorized wheels to propel the imaging unit. The electric traveling unit is equipped with high-torque motors capable of overcoming the friction between the heavy imaging unit and the floor, as well as the brake resistance. This mechanical-to-electrical substitution enables heavy units to be moved easily without requiring large manual forces.
3Device complexity
If the driving force is small, then device complexity is reduced, but the unit cannot be pulled when resistance is high
Solution Approach 1:
The electric traveling unit is designed as a multi-functional device that combines both manual traveling support and electric traveling capabilities in a single unit. It integrates brake release mechanisms, motorized wheels, and control systems that can adapt to different operating conditions. This universal design allows the same device to handle both light and heavy imaging units, and to switch between manual and electric modes, maximizing pulling capability without proportionally increasing complexity.
