Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position switches for movement and transport plants, such as elevators and hoists, face challenges in precise adjustment and maintenance due to complex installation requirements and a high risk of losing adjustment position over time, necessitating expert skills and frequent maintenance.
Innovation Solution
A position switch design with integrated adjustment means within the box-like case, allowing for precise adjustment of the actuator position relative to the fixed part, featuring a first adjustment member anchored to the plant and a second member movable within the case, enabling simplified and precise positioning without requiring external alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external brackets with slots are used for mounting the switch, then adjustment capability is provided, but adjustment precision is limited and device complexity increases
Solution Approach 1:
The adjustment bracket is nested within the switch housing, with the bracket integrated into the case structure. The actuator assembly is nested within the bracket, allowing multi-level adjustment while maintaining a compact form factor. This nesting approach enables precise adjustment without requiring external mounting components.
Solution Approach 2:
The adjustment mechanism is divided into segmented components: the housing provides primary positioning, the internal bracket provides secondary adjustment, and the actuator assembly provides fine-tuning capability. This segmentation allows each component to contribute to overall precision without requiring any single component to be overly complex.
2Ease of operation
If complex external mounting solutions are used, then adjustment capability is achieved, but installation difficulty increases and expert skill is required
Solution Approach 1:
The mounting bracket and adjustment mechanism are merged into a single integrated assembly that is pre-mounted to the switch housing. This eliminates the need for separate external brackets and simplifies installation to a single mounting operation, making the device accessible to operators without expert skill levels.
Solution Approach 2:
The adjustment bracket and actuator positioning are pre-configured during manufacturing, with preliminary adjustment capabilities built into the housing structure. This preliminary action reduces on-site installation complexity and allows standard operators to complete installation without requiring expert knowledge.
3Productivity
If traditional mounting methods are used, then the switch can be installed, but adjustment position is lost after high number of cycles requiring continuous maintenance
Solution Approach 1:
The adjustment bracket incorporates dynamic retention features that automatically maintain the adjustment position through activation/deactivation cycles. The design includes self-locking or friction-based retention mechanisms that adapt to repeated use, preventing position drift without requiring continuous maintenance intervention.
4Measurement precision
If the actuator positioning requires millimetric precision, then accurate stop position control is achieved, but the positioning difficulty and adjustment complexity increases
Solution Approach 1:
The adjustment mechanism utilizes multi-dimensional adjustment capabilities: the bracket can be positioned along the longitudinal axis of the housing, while the actuator assembly can be adjusted perpendicular to the housing face. This dimensional approach enables millimetric precision through simple linear adjustments rather than complex multi-axis positioning.

AI summary
A position switch for a movement or transport plant comprises a box-like case (2) anchorable to a fixed part (F) of the plant at the end position of a movable part of the plant and intended to house therein at least one pair of reciprocally movable electric contacts connectable to an electric circuit of the plant, actuator means (3) mounted in the case (2) and operatively associable with the electric contacts in order to interact with the movable part of the plant when the latter reaches the end position and to cause the opening and/or closing the circuit, and adjustment means (9) for adjusting the position of the actuator means (3) integrated in the case (2) in order to cause the translation thereof integrally with the actuator means (3).
