Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact devices for busbars fail to maintain a defined contact when the busbars tilt relative to each other, particularly when they have different widths or angular tolerances, leading to poor electrical connectivity.
Innovation Solution
A contact device with a clamping unit and a contact unit that are spaced apart to accommodate busbars of varying widths, featuring a displaceable contact element and a connecting element that can adjust to compensate for angular errors and unevenness, ensuring reliable electrical contact through a gap that can be adjusted to fit different busbar widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed contact device is used to contact busbars, then the structure is simple, but it cannot compensate for angular errors and unevenness when busbars tilt relative to each other
Solution Approach 1:
The contact element is designed to be displaceable relative to the contact jaw, allowing it to dynamically adjust its position to accommodate angular errors and unevenness in busbar alignment. This dynamic capability ensures reliable electrical contact while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If the contact device is designed for fixed busbar width, then the structure is simplified, but it cannot accommodate busbars of different widths
Solution Approach 1:
The gap between the clamping unit and contact unit is designed to be adjustable, enabling the device to adapt to busbars of different widths. The displaceable contact element further enhances this adaptability by allowing fine-tuning of the contact position within the gap.
3Reliability
If the contact element is fixed on the contact jaw, then the structure is simple, but it cannot compensate for angular tolerances and unevenness
Solution Approach 1:
The contact element is designed to be displaceable relative to the contact jaw, allowing it to dynamically adjust its position to accommodate angular errors and unevenness in busbar alignment. This dynamic capability ensures reliable electrical contact while maintaining a relatively simple overall device structure.
4Adaptability or versatility
If the clamping unit and contact unit are positioned close together, then the device size is reduced, but the gap is insufficient to accommodate busbars of varying widths
Solution Approach 1:
The adjustable gap between the clamping unit and contact unit provides the necessary space to accommodate busbars of varying widths. The displaceable contact element allows the effective contact position to be optimized within this gap, maintaining compact device dimensions while preserving adaptability.

Function Achieved in This Case
The device provides consistent and reliable electrical contact for busbars of different widths and with angular tolerances, ensuring good connectivity even when covered with insulating materials, by allowing for precise adjustment of the gap between the clamping and contact units.
Implementation Method 1
the pin in said hole is loaded with a spring, the spring pushing the pin towards the surface as seen from the hole. The spring force acts in the direction of the gap.
