Robot Fixing Apparatus with Conical Positioning and Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems lack a reliable and accurate method to securely fix a movable robot to an external structure, such as a floor surface, while allowing for precise positioning and preventing accidental movement or falls during operation.
Innovation Solution
A fixing apparatus comprising a first unit and a second unit with a positioning mechanism and a lock mechanism, utilizing complementary conical surfaces and a clamp mechanism to securely lock the robot's truck to the external structure, ensuring accurate positioning and preventing movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable robot is used to travel between stations on a production line, then flexibility and adaptability are improved, but positioning accuracy and stability deteriorate
Solution Approach 1:
The positioning mechanism performs preliminary positioning of the robot body relative to the truck before the locking mechanism engages. This ensures that the robot is accurately positioned in advance, allowing the movable robot to achieve both mobility and positioning accuracy by preparing the position beforehand rather than relying solely on active control during movement.
2Reliability
If a locking mechanism is added to fix the robot to the external structure, then stability and reliability are improved, but device complexity increases
Solution Approach 1:
The positioning mechanism and locking mechanism are merged into an integrated fixing apparatus. The positioning mechanism determines the relative relationship between the robot and external structure, while the locking mechanism secures this positioned state. By combining these functions into one unified apparatus rather than separate systems, the invention achieves high fixing reliability while minimizing the increase in device complexity.
3Reliability
If the robot is firmly fixed to prevent movement, then safety and reliability are improved, but ease of operation and repositioning worsen
Solution Approach 1:
The fixing apparatus transitions from a static to a dynamic system. The robot can be easily moved between stations by simply detaching the locking mechanism, then firmly fixed at target positions by engaging the locking mechanism after positioning. This dynamic capability allows the system to switch between mobility and stability as needed, maintaining both safety during operation and ease of repositioning.
