Press Cover Support Locking to Prevent Hand Pinching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Press cover apparatuses pose a safety hazard as they can suddenly fall and pinch the user's hand during operation due to faulty mechanisms, leading to potential injury.
Innovation Solution
A press cover anti-pinch device is designed with a connector and support system that swings down to support the press cover when open, featuring a locking mechanism and reset member to ensure stability and automatic resetting, preventing the press cover from falling and enhancing user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the press cover is opened for operation, then the user can access the working area, but the press cover may fall down and pinch the user's hand
Solution Approach 1:
The support structure is activated in advance to hold the press cover in the open position before the user completes their operation. This preliminary supporting action prevents the cover from falling during the entire working period, eliminating the pinching hazard while maintaining easy access to the working area.
Solution Approach 2:
The support structure acts as an intermediary element between the press cover and the supporting surface. It mediates the load-bearing function, transferring the weight of the open press cover to the supporting surface, thereby preventing the cover from falling and pinching the user's hand while allowing uninterrupted access to the working area.
2Object-affected harmful factors
If a support structure is added to prevent the press cover from falling, then safety is improved, but the device complexity increases
Solution Approach 1:
The support structure is designed to be self-activating through the reset member mechanism. When the press cover is opened, the reset member automatically engages the support structure to hold the cover in position. This self-service feature eliminates the need for external control systems, sensors, or power sources, thereby preventing press cover falling while avoiding significant increases in device complexity.
Solution Approach 2:
The invention replaces complex electronic control systems with a purely mechanical solution. The reset member and support structure use mechanical interlocking and elastic deformation to achieve automatic engagement and disengagement, providing press cover falling prevention through simple mechanical means rather than complex electronic or hydraulic systems.
3Ease of operation
If the support is made to swing down automatically, then ease of operation is improved, but the reliability of locking position decreases
Solution Approach 1:
The support structure is preliminarily positioned and pre-loaded with elastic energy in the reset member. When the press cover is opened, the support automatically swings down to the supporting position and locks into place before the user begins operation. This preliminary locking action ensures reliable positioning while maintaining ease of operation through automatic activation.
Solution Approach 2:
The support structure performs self-locking through the mechanical interaction between the support arm and the locking mechanism. The elastic force from the reset member automatically engages the locking feature when the support reaches the supporting position, ensuring reliable locking without requiring external intervention. The same mechanism automatically disengages the lock when the press cover is closed, maintaining ease of operation.

AI summary
A press cover anti-pinch device and an apparatus having a press cover is disclosed. The press cover anti-pinch device comprises: a connector arranged at a lower side of a cover body of the press cover and fixed to the press cover; and a support hinged to the connector and rotatably arranged in a supporting position or in a collapsed position, wherein when the support is arranged in the supporting position, the support swings down and supports the press cover on a supporting surface, and when the support is arranged in the collapsed position, the support is collapsed and the press cover is lowered. During use, when the press cover is in an opened state, the support swings down and supports the press cover on the supporting surface, so that the support provides a supporting force to the press cover.
