Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caliper style brakes face issues with leakage, deflection of components, and inefficient fluid transmission due to multiple input and output ports, leading to assembly challenges and air bleeding inefficiencies.
Innovation Solution
A hydraulic caliper brake design featuring a housing with aligned holes and recessed areas for proper stator placement, a bridge connecting housing halves with a single input and output port for fluid transmission, and O-rings and seals to prevent fluid leakage, along with a bleed system for efficient air removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate is used to cover the through bore and secured with seals, then the bore is sealed, but the plate is susceptible to deflection and leaks occur between the plate and housing
Solution Approach 1:
The single through-bore plate is segmented into multiple smaller bore covers distributed around the caliper housing. Each small bore cover is independently supported by the housing structure, eliminating deflection issues while maintaining sealing effectiveness through localized seal arrangements at each bore location.
2Adaptability or versatility
If multiple input and output ports are used for fluid transmission, then brake fluid supply and air bleeding are achieved, but the system becomes complex and assembly is difficult
Solution Approach 1:
Multiple fluid transmission functions are merged into a single through-bore structure. The bore passes through the caliper housing and provides multiple sealed access points for brake fluid supply and air bleeding operations, consolidating what would traditionally require multiple separate ports into one integrated structure.
Solution Approach 2:
The single through-bore structure serves multiple functions: it provides pathways for brake fluid supply, enables air bleeding operations, and maintains structural integrity. This multi-functional design eliminates the need for separate dedicated ports for each function, simplifying the overall system.
3Device complexity
If a single input and output port is used for fluid transmission, then the system is simplified, but fluid transmission efficiency may be reduced
Solution Approach 1:
The single through-bore is utilized in multiple spatial dimensions and orientations within the caliper housing. By strategically positioning multiple sealed access points along the bore at different locations and angles, the design achieves efficient fluid distribution to multiple pistons while maintaining a simple single-bore structure.

AI summary
A hydraulic caliper brake includes a housing formed by two halves. A pair of bores are provided in each housing half, and a piston is positioned in each bore. An end cap closes off each bore and is sealed by an O-ring positioned around the periphery of each end cap. A ring retains each end cap within each bore. Each housing half has a pair of holes aligned with the holes of the other half. A pair of recessed areas are located on opposing ends of the housing, one of the recessed areas being positioned adjacent to one housing half and the other being positioned adjacent to the other housing half. A pair of stator plates each have a first ear with an outer shape having a flattened area positioned within one of said recessed areas in said housing, and a second ear with a continuously curved outer shape. Each ear has a hole therethrough aligned with the holes of the housing halves, and a pin is positioned in the aligned holes. An easily bleedable fluid network supplies fluid to the pistons.
