Solution Overview
Problem
Existing head protection gear designs fail to maintain a stable coupling state between the visor and the main frame while also allowing for easy release and rotation of the visor.
Innovation Solution
A head protection gear design featuring a visor locker coupled to the main frame, with a movable member and support member that allow the visor to be securely locked and easily released by applying a directional force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fastening protrusion and fastening recessed portion combination is used to maintain coupling state, then the coupling stability is improved, but the ease of rotation is worsened
Solution Approach 1:
The patent employs a dynamic locking mechanism where the locking protrusion can move between a locked position (engaging with the locking groove) and an unlocked position. This allows the system to transition between stable coupling and easy rotation states as needed, resolving the contradiction between maintaining stability and enabling ease of operation.
Solution Approach 2:
The locking protrusion acts as an intermediary element between the visor and the locking groove. By introducing this intermediate component that can be actuated by a pressing member, the patent enables controlled engagement and disengagement without requiring direct manipulation of the visor itself, thus maintaining stability when locked while facilitating easy rotation when unlocked.
2Ease of operation
If a locking groove and hook combination is used for detachable coupling, then the ease of detachment is improved, but the rotation limitation is worsened
Solution Approach 1:
The locking protrusion provides dynamic control over the coupling state. When engaged with the locking groove, it limits rotation and maintains stability. When disengaged by pressing, it allows easy detachment. This dynamic mechanism resolves the contradiction by enabling both rotation limitation and ease of detachment as needed.
Solution Approach 2:
The pressing member automatically actuates the locking protrusion to disengage from the locking groove, enabling self-service detachment without requiring manual manipulation of the visor or frame. This automatic mechanism improves ease of detachment while maintaining rotation limitation when the locking protrusion is engaged.
3Ease of operation
If the visor is designed to be rotatable for easy opening, then the ease of operation is improved, but the coupling stability is worsened
Solution Approach 1:
The locking mechanism provides dynamic control that allows the visor to be stable when locked and easily rotatable when unlocked. The pressing member enables the user to transition between these states, resolving the contradiction between coupling stability and ease of opening by making both states achievable as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
