Protector Cover Mounting with Sensor-Based Press Force Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual attachment of protector covers to protector main bodies is challenging due to difficulties in adjusting the pressing force, leading to incomplete locking or excessive load application.
Innovation Solution
An automatic protector cover mounting device with a presser mechanism that adjusts pressing force using a sensor to detect proper alignment and prevent overloading, ensuring secure attachment through a controlled pressing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If machine automatic attachment is used, then productivity is improved, but manufacturing precision deteriorates due to difficulty in adjusting pressing force
Solution Approach 1:
The patent employs a sensor to detect the pressing force applied to the protector cover and provides feedback to the control unit. The control unit adjusts the pressing force based on this feedback to achieve the optimal locking force, resolving the contradiction between automated high-speed attachment and precise force control.
Solution Approach 2:
The system dynamically changes the pressing force parameter during the attachment process. The control unit adjusts the magnitude of the pressing force based on sensor feedback and pre-stored optimal values, enabling precise control in an automated system.
2Reliability
If pressing force is increased to ensure locking, then reliability is improved, but object-generated harmful factors worsen due to excessive load on the protector
Solution Approach 1:
The sensor detects the actual pressing force and provides feedback to the control unit, which adjusts the force to the optimal level needed for reliable locking. This prevents excessive loading while ensuring the lock receiving portion is securely locked to the locking portion.
Solution Approach 2:
The system applies just enough pressing force to achieve reliable locking without over-pressing. By using sensor feedback to detect when the optimal locking force is achieved, the system avoids excessive action that would cause harmful loads on the protector.
3Object-generated harmful factors
If pressing force is decreased to reduce load, then object-generated harmful factors are reduced, but reliability deteriorates due to failing to lock the lock receiving portion
Solution Approach 1:
The sensor continuously monitors the pressing force and provides feedback to the control unit. This ensures that the pressing force never drops below the threshold required for reliable locking, while also preventing excessive force application.
Solution Approach 2:
The control unit dynamically adjusts the pressing force parameter based on sensor feedback, maintaining it within the optimal range that ensures reliable locking while minimizing excessive load on the protector.

AI summary
An automatic protector cover mounting device includes: a protector holding section for holding a protector main body; an operating section for attaching a protector cover to the protector main body; a movement means for moving the operating section. The operating section includes: a presser for pressing the protector cover toward the protector main body; a base with the presser mounted thereto, the presser being mounted to the base to be extendable out of the base and retractable into the base; and a sensor configured to detect a opposite amount of protrusion of the rod of the presser out of the base in a direction opposite to the protector holding section. Upon the opposite amount of protrusion of the rod being greater than or equal to a predetermined amount, the control section is configured to stop a pressing operation of the presser.
