Concrete Broom Protector with Pivot Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concrete broom bristles often become bent or damaged during non-use, making subsequent use difficult and affecting the finish of concrete surfaces, as existing protectors with hooks complicate the movement between clamping and non-clamping positions.
Innovation Solution
A protector with pivotally connected clamping members and a transversely extending handle on the clamping lever allows easy movement between open and closed positions, securely clamping the bristles to prevent damage and facilitate handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook is provided at the outer end of the clamping lever to hang the protector during non-use, then the protector can be conveniently stored, but it becomes difficult to grasp and move the clamping member between positions
Solution Approach 1:
The clamping lever is segmented into two functional zones: the inner end maintains the hook for storage hanging, while the outer end adds a transverse handle for grasping and movement. This segmentation allows both storage convenience and ease of operation to coexist without interference.
Solution Approach 2:
The transverse handle acts as an intermediary element that facilitates the movement operation without interfering with the hook's storage function. By providing a dedicated grasping surface, it mediates between the user's hand and the clamping mechanism, making movement easier while preserving the hook's utility.
2Reliability
If the clamping members are made secure to firmly clamp the bristles, then the bristles are protected from damage, but the mechanism becomes more complex
Solution Approach 1:
The protective function is extracted from the clamping action itself. The clamping members provide both the clamping force for protection and the structural framework, eliminating the need for separate protective elements and reducing overall complexity while maintaining effectiveness.
Solution Approach 2:
The clamping members serve multiple functions simultaneously: they provide the clamping force to protect bristles, form the structural framework of the protector, and work with the pivot to enable movement between positions. This multi-functionality reduces the need for additional components.
