Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic piston resetting tools for disk brake calipers are limited in their ability to accommodate calipers of various sizes due to fixed displacement ranges, making them unsuitable for both large and small caliper sizes without increasing the tool's thickness.
Innovation Solution
A hydraulic piston resetting tool with a main body, first and second pressing plates, and a holding pole, featuring a system of interconnected chambers and cylinders that allow for adjustable displacement without increasing the tool's thickness, utilizing working fluid to reset pistons in calipers of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the displacement range of the stopping piece is increased to force the piston back into large-size calipers, then the tool can reset pistons in large calipers, but the thickness of the tool body increases, making it impossible for the tool to enter calipers of smaller sizes
Solution Approach 1:
The tool body is divided into multiple telescopic segments (first telescopic section, second telescopic section, third telescopic section) that can independently extend and retract. This segmentation allows the tool to achieve variable thickness - thin for small calipers and thick for large calipers - by controlling which segments are extended, thereby resolving the contradiction between adaptability and tool thickness.
Solution Approach 2:
The tool employs a dynamic thickness design where the stopping piece can be positioned at different distances from the pressing plate through telescopic mechanisms. This dynamic adjustment capability allows the tool to adapt its displacement range to match different caliper sizes without permanently increasing its base thickness, enabling the tool to enter both small and large calipers effectively.
2Ease of operation
If the tool body thickness is increased to provide sufficient displacement range for large calipers, then the piston can be forced back in large calipers, but the tool cannot enter calipers of smaller sizes
Solution Approach 1:
The pressing plate assembly is segmented into multiple telescopic sections that can extend independently. This allows the tool to provide sufficient pressing force and displacement for large calipers when needed, while maintaining a compact profile for entering smaller calipers, thus achieving both ease of operation and versatility.
Solution Approach 2:
The telescopic sections are nested within each other, with the second telescopic section inside the first, and the third inside the second. This nested structure allows the tool to compactly store its extended length when not in use, enabling it to enter small calipers, while still providing the full extended displacement range when working with large calipers.
