Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mitered edge clamping systems for materials like granite and quartz countertops are inefficient, requiring excessive manpower, leading to material loss, potential injury, and poor seam alignment due to limitations in size, angle accommodation, and reliance on additional stabilization methods.
Innovation Solution
A portable clamping system using vacuum base plates with a pivoting knuckle assembly and worm drive mechanism that allows for precise alignment and secure attachment of mitered edges, enabling single-worker operation and repositioning without misalignment for adhesive application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional bar clamps and multiple workers are used to hold and clamp mitered edges, then firm clamping and alignment are achieved, but excessive manpower is required and the risk of injury and material loss increases
Solution Approach 1:
The patent replaces the manual mechanical clamping system with a pneumatic vacuum clamping system. The vacuum clamps use suction force generated by a vacuum pump to hold and align mitered edges, eliminating the need for multiple workers to manually position and clamp the materials. This substitution maintains strong clamping force while dramatically reducing manpower requirements and injury risk.
Solution Approach 2:
The invention employs pneumatic principles through vacuum-generated suction forces to achieve firm clamping of mitered edges. The vacuum clamps create a pressure differential that firmly holds the materials in alignment without requiring manual intervention, thus providing strong clamping force with minimal human effort.
2Reliability
If rigid vacuum pads are used for clamping, then secure attachment is achieved, but the system is limited in size accommodation and requires additional stabilization methods
Solution Approach 1:
The patent employs flexible vacuum pads that can dynamically adapt to different slab sizes and shapes. These flexible pads can be configured in various arrangements and can conform to the surface of materials of different dimensions, providing secure attachment while accommodating a wide range of sizes without requiring additional stabilization methods.
Solution Approach 2:
The invention uses flexible vacuum pads instead of rigid ones, allowing the pads to conform to different material surfaces and sizes. This flexibility enables the system to securely attach to various slab dimensions while maintaining reliable clamping, eliminating the need for additional stabilization methods.
3Reliability
If multiple additional suction cup attachments are used to prevent side slipping, then seam security is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple functions into a single integrated vacuum clamp system. The flexible vacuum pads can be arranged in configurations that simultaneously provide clamping force and prevent side slipping, eliminating the need for separate additional suction cup attachments. This merging of functions reduces device complexity while maintaining seam security.
4Manufacturing precision
If conventional clamping methods are used, then alignment can be achieved, but fabrication time is excessive due to manual positioning and clamping
Solution Approach 1:
The patent replaces manual mechanical positioning and clamping with an automated pneumatic vacuum system. The vacuum clamps can quickly attach to and align multiple mitered edges simultaneously, and the flexible pads can be rapidly repositioned for adhesive application and re-clamping, dramatically reducing fabrication time while maintaining alignment precision.
5Strength
If direct attachments against sharp seam edges are used, then clamping is achieved, but visual inspection is obscured and risk of edge damage increases
Solution Approach 1:
The patent introduces flexible vacuum pads as intermediaries between the clamping system and the sharp mitered edges. These pads distribute the clamping force over a larger surface area and do not directly contact the vulnerable edge points, preventing edge damage while maintaining effective clamping force. The pads also allow unobstructed visual inspection of the seam area.

AI summary
A clamping system and method useful in miter edge fabrication. Two separate units, each including a vacuum plate may be placed on separate slabs. The units may be connected with a knuckle that can be rotated to provide connection of the slabs in a variety of angles. The units are vacuum sealed to the slabs. The vacuum plates may include various sections of varied sizes to connect to different sized slabs. When the knuckle is locked, a worm gear will provide for lateral movement, relative the knuckle, to provide precision fitting of slabs.
