Adjustable Grinding Surface with Rotatable Motor Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disk grinders and sanders are limited to a single orientation, requiring multiple devices or complex reconfiguration methods to accommodate various sanding or grinding applications, which is costly and inefficient for users needing multiple orientations.
Innovation Solution
An adjustable grinder system with a rotatable motor support and locking mechanism, allowing the grinding orientation to be adjusted between vertical and horizontal positions, and any intermediate angles, using slotted cutouts and arms secured to a grinder base for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple grinders or sanders in different orientations are purchased to accommodate various sanding or grinding applications, then adaptability to different orientations is improved, but device complexity and cost increase
Solution Approach 1:
The grinder base is designed to accommodate the grinding device in multiple orientations (vertical, horizontal, and intermediate angles) through a single unified structure. The base includes a mounting surface that can be positioned at different angles, allowing one grinder to perform functions that previously required multiple separate devices.
Solution Approach 2:
The mounting mechanism includes adjustable and reconfigurable components that allow the grinding device to be dynamically repositioned between different orientations. The base structure enables smooth transitions between vertical and horizontal positions, as well as intermediate angles, making the system adaptable rather than fixed.
2Adaptability or versatility
If brackets are used to reconfigure the grinder orientation, then adaptability is improved, but ease of operation deteriorates due to tool requirements and complex processes
Solution Approach 1:
The mounting mechanism is designed to be adjusted and reconfigured by the user without requiring external tools or complex procedures. The base includes self-contained adjustment features that allow direct manipulation by hand, eliminating the need for additional tools or complicated assembly/disassembly processes.
3Device complexity
If a fixed single-orientation grinder design is used, then device complexity is reduced, but adaptability to multiple sanding or grinding applications is limited
Solution Approach 1:
The grinder system is divided into separate functional components: the grinding device itself and the adjustable base. This segmentation allows the base to be independently designed with multiple positioning capabilities while keeping the grinding device simple and unchanged. The mounting surface is a separate element that can be repositioned without affecting the core grinding mechanism.

AI summary
An adjustable grinding apparatus includes a grinder having a motor and grinding disk. A grinder base houses the motor. The grinder base has at least one sidewall extending around at least a portion of the motor. An adjustable motor support includes a motor support surface positioned between the motor and the grinding disk. First, second arms are affixed to first and second ends of the motor support surface and rotatably secured to the at least one sidewall. At least one of the first, second arms has at least one slotted cutout. A locking mechanism is in communication with at least one of the first and second arms and the at least one sidewall through at least one slotted cutout. The grinder and the adjustable motor support are rotatable about the grinder base to adjust a grinding orientation of the grinder. A grinder position is fixable by tightening the locking mechanism.
