Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road devices, such as access hatches, are difficult to assemble and handle due to complex securing mechanisms and require multiple parts, making them costly and inefficient, and lack ease of retrofitting for existing systems.
Innovation Solution
A road system design featuring a frame with a buffer that includes maneuvering recesses and cam mechanisms for easy handling and assembly, with support brackets made in one piece for simplified assembly and integration, allowing for easy transition between closed and open positions, and enabling retrofitting of existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional securing means are used to secure the buffer to the frame, then the buffer is securely fixed, but the assembly becomes complex and expensive with many spare parts
Solution Approach 1:
The patent combines multiple functions into a single support bracket component. The support bracket integrates the securing function (holding the buffer), the hinge function (allowing rotation), and the cam mechanism (enabling latching) into one unified part, eliminating the need for separate securing means and reducing overall assembly complexity
Solution Approach 2:
The support bracket serves multiple functions simultaneously: it acts as a mounting structure for the buffer, provides a hinge axis for rotation, incorporates a cam mechanism for latching, and includes maneuvering recesses for tool engagement. This multi-functionality reduces the total number of components needed in the system
2Reliability
If traditional securing means with many parts are used, then the buffer is securely fixed, but assembly and maintenance become difficult and expensive
Solution Approach 1:
The support bracket merges multiple components into a single integrally formed piece that can be manufactured in one operation. The cam mechanism, hinge axis, and securing features are all formed as part of the same component, dramatically simplifying manufacturing and assembly processes
Solution Approach 2:
The buffer is divided into functional zones with maneuvering recesses positioned at specific locations. These recesses allow tools to engage with the buffer at optimal points for lifting, rotating, and latching operations, making handling easier without adding complexity to the overall structure
3Ease of operation
If the buffer is designed for easy handling with maneuvering recesses, then operation becomes simpler, but the structure becomes more complex
Solution Approach 1:
The buffer's maneuvering recesses are designed to work with simple external tools rather than requiring complex built-in mechanisms. The recesses guide tool placement and automatically align with the buffer's movement paths, allowing the buffer structure itself to facilitate its own handling without adding separate actuation systems
Solution Approach 2:
The same maneuvering recesses serve multiple operational functions: they provide lift points for raising the buffer, guide edges for aligning during installation, and engagement points for tools during latching operations. This multi-functionality reduces the need for separate features for each operation
4Adaptability or versatility
If existing road systems are to be retrofitted, then upgrade becomes possible, but assembly and installation become more difficult
Solution Approach 1:
The support bracket is designed as a modular component that can be independently installed on existing frames. The bracket segments the buffer mounting function from the frame structure, allowing the bracket to be attached to various frame types without modifying the original frame, thereby facilitating retrofitting while keeping installation straightforward
