Cold Knife Holder Push-Pull Mechanism for Windshield Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold knife holders for dismounting automobile windshields are cumbersome and require complex operations due to the vehicle's width exceeding the operator's arm length, making it difficult to efficiently pierce and remove the sealing element in a single operation.
Innovation Solution
A cold knife holder with a columnar main body, handle, detent member, spring, and steel ball mechanism that allows for both pushing and pulling operations, enabling the blade to be easily maneuvered across the windshield's width by rotating the handle to position the cutting part on either side of the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator uses a traditional cold knife holder with single-direction pull operation, then the structure is simple, but the operator cannot efficiently move the cutting part across the windshield's width in one operation due to arm length limitations
Solution Approach 1:
The cold knife holder incorporates a movable detent member that can switch between a first position (for pushing operation) and a second position (for pulling operation). This dynamic reconfiguration allows the same device to perform both pushing and pulling actions, enabling the operator to move the cutting part across the windshield's width efficiently in one operation without requiring multiple separate tools or complex repositioning procedures.
2Productivity
If the operator performs multiple repositioning operations to move the cutting part across the windshield, then the blade can reach all areas, but the operating procedure becomes complicated and time-consuming
Solution Approach 1:
The detent member's ability to switch between positions enables the cold knife holder to change its operational mode from pushing to pulling without removing the blade or repositioning the entire tool. This dynamic adjustment allows the operator to maintain continuous work on the sealing element destruction, eliminating the need for multiple repositioning operations and significantly reducing the time and complexity of the overall procedure.
3Adaptability or versatility
If the cold knife holder uses a fixed single-mode operation, then the structure is simple, but it cannot adapt to different operating positions and directions required by the vehicle's width
Solution Approach 1:
The cold knife holder incorporates a movable detent member that can switch between a first position (for pushing operation) and a second position (for pulling operation). This dynamic reconfiguration allows the same device to perform both pushing and pulling actions, enabling the operator to move the cutting part across the windshield's width efficiently in one operation without requiring multiple separate tools or complex repositioning procedures.

Function Achieved in This Case
Enhances usability by simplifying the process of destroying the sealing element, allowing the blade to be efficiently moved across the windshield's width without the need for complex repositioning, thereby facilitating easier removal of the windshield.
Implementation Method 1
a first spring arranged in said chamber, both ends of said first spring prop said abutting surface and said detent member respectively
Implementation Method 2
a first steel ball pivotally embedded in said perforation, said first steel ball laterally props said detent member, so that said detent member drives said first steel ball to be embedded in said first hole or said second hole

AI summary
A cold knife holder capable of pushing and pulling operations, includes a main body forming a chamber and a slot, a handle, a detent member, a first spring and a first steel ball. One side of the main body forms a perforation which communicates with the chamber. The handle includes a sleeve, a connecting rod and a grip rod. Both ends of the connecting rod are respectively connected to the sleeve and the grip rod, and the sleeve is pivotally sleeved on the main body, so that the handle is rotated relative to the main body, and the first or second caulking is connected to the perforation, and the detent member is arranged in the chamber. The first steel ball is pivotally embedded in the perforation, so that the detent member drives the first steel ball to be embedded in the first or second caulking, thereby positioning the handle.
