Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor processing systems require adaptable ladder systems that can accommodate various types of platforms and process modules while ensuring safety during maintenance, as different process modules have different footprints, leading to increased cost and complexity due to the need for multiple ladder types.
Innovation Solution
A modular ladder system with a vertical support, angled ladder, and adaptable parts such as foldable hinged step covers and guard rails that can be deployed based on the type of processing module to provide fall prevention barriers, allowing the ladder to dock with different platform sections and adjust to varying shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different ladder types are used for different process modules, then safety and proper access are ensured, but cost and complexity increase due to needing to store and coordinate multiple ladder types
Solution Approach 1:
The ladder system is designed with universal components that can accommodate different process module configurations. The ladder bridge mount can be positioned at various locations and the adaptable parts can be configured to match different footprints, allowing a single ladder system design to serve multiple platform types without requiring separate dedicated ladders for each module type.
Solution Approach 2:
The ladder system is divided into modular segments including the ladder bridge mount, vertical support, and adaptable parts that can be independently configured. This segmentation allows the same basic ladder structure to be adapted to different process modules by reconfiguring the modular components rather than requiring entirely different ladder types.
2Ease of operation
If different ladder types are used for different process modules, then proper access is ensured, but cost increases due to needing to store and coordinate multiple ladder types
Solution Approach 1:
A single universal ladder system design can provide proper access to different process modules through configurable components. This eliminates the need to manufacture and stock multiple specialized ladder types, reducing manufacturing costs and inventory requirements while maintaining the ability to properly access various module configurations.
Solution Approach 2:
The ladder system incorporates dynamic and adjustable components such as the adaptable parts that can be reconfigured based on the specific process module being accessed. This dynamic adaptability allows one ladder system to serve multiple purposes, reducing the need for multiple static ladder types and associated costs.
3Ease of manufacture
If a fixed ladder design is used, then manufacturing is simpler, but adaptability to different platform configurations is reduced
Solution Approach 1:
The ladder system is segmented into standardized modular components that maintain manufacturing simplicity through repetition of proven designs, while the configurable adaptable parts provide the necessary adaptability to different platform configurations without requiring entirely new manufacturing processes.
Solution Approach 2:
The system combines fixed standardized components with dynamic configurable elements. The fixed portions maintain manufacturing simplicity and reliability, while the adaptable parts can be adjusted or reconfigured to match different process module footprints, achieving both manufacturing efficiency and adaptability.

AI summary
A modular ladder system is provided. The modular ladder system includes a vertical ladder assembly including a vertical support with a ladder bridge mount that is configured to dock with a first section of the platform and an angled ladder. The vertical support may also include one or more adaptable parts that is configured to provide a fall prevention barrier according to a shape of the process module. The adaptable part may be a foldable hinged step cover that couples with a second section of the platform or one or more guard rails that rest below the ladder bridge mount in a stowed position and is coupled with the ladder bridge mount. Further, the vertical support and the angled ladder may be detachable. The angled ladder may include an extension plate that provides a bridge between ladder bridge mount and a swing gate of the ladder system.
