Busbar Adapter Segmented Chamber for 180° Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar adapters can only be placed on busbars in a predetermined position, limiting flexibility and accessibility of connection contacts.
Innovation Solution
The adapter features chambers with twice the length of clamp straps, allowing clamping brackets to be used in two positions, enabling rotation by 180° for flexible positioning of connection contacts, and includes cover elements for safety and adjustable connecting rails for variable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adapter is designed with fixed clamping bracket positions, then the structure is simple and easy to manufacture, but the adapter can only be placed in a predetermined position, reducing flexibility and accessibility
Solution Approach 1:
The chamber is divided into two separate chamber sections (first and second chamber sections) along the longitudinal axis. Each chamber section can independently receive a clamping bracket, allowing the adapter to be placed on busbars in different orientations. This segmentation enables the adapter to accommodate clamping brackets at different positions without requiring a completely different adapter design.
Solution Approach 2:
The single chamber with two chamber sections serves multiple functions: it can receive clamping brackets in either the first or second chamber section depending on the desired placement orientation. This multi-functionality allows the same adapter design to be used for different installation scenarios, eliminating the need for multiple specialized adapter variants.
2Reliability
If the clamping brackets are made of metal to conduct current, then electrical conductivity is improved, but the risk of electric shock increases and safety is reduced
Solution Approach 1:
The housing acts as an intermediary component between the metal clamping brackets and the external environment. It provides electrical insulation while allowing the metal clamping brackets to maintain electrical contact with the busbars. This mediator approach enables current conduction through the clamping brackets while preventing electric shock risks to users.
Solution Approach 2:
The electrical insulation function is extracted from the clamping brackets themselves and assigned to the housing. The clamping brackets can be made of metal for optimal electrical conductivity, while the housing provides the necessary insulation barrier, separating the conductive function from the safety function.
3Ease of operation
If the connection contacts are always accessible from the top, then accessibility is improved, but the adapter cannot be rotated 180°, reducing placement flexibility
Solution Approach 1:
The chamber is segmented into two chamber sections positioned at different locations along the longitudinal axis. This segmentation allows clamping brackets to be received at different positions, enabling the adapter to be placed in multiple orientations (including 180° rotation) while maintaining proper electrical connections and accessibility.
Solution Approach 2:
The solution moves from a single fixed contact position to multiple contact positions along the longitudinal dimension. By distributing chamber sections along the length of the adapter, the design enables rotational flexibility while maintaining accessibility from different directions depending on the placement orientation.

AI summary
The adapter (1) has a housing for accommodating connection bars, and clamping brackets (10-12) for attachment of the housing to bus bars (2-4). A cover plate (30) covers the connection bars in a touch-proof manner. Chambers (6-8) are provided for the accommodation of the brackets, where each chamber is formed by two chamber sections. The sections are arranged in a direction transverse to the bus bars for alternative accommodation of the brackets. The sections have dimension that is larger than the width of the bus bars in longitudinal direction of an adapter.
