Solar Module End Holder With Sawtooth Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for solar modules lack versatility and ease of installation, particularly for modules of different heights, as they often require stepwise height adjustments and are not easily adaptable to various dimensions.
Innovation Solution
A height-adjustable end bracket with a receiving angle element and a fastening element featuring sawtooth profiles allows for virtually stepless height adjustment by enabling relative movement between the elements, ensuring precise and secure mounting of solar modules of varying heights using a screw-based adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a height-adjustable end bracket with sawtooth profiles is used, then height adjustment precision and versatility are improved, but device complexity increases
Solution Approach 1:
The adjustment element acts as an intermediary mechanism between the receiving angle element and fastening element. It translates rotational motion into linear displacement, enabling precise height adjustment without requiring complex direct adjustment mechanisms on both components.
Solution Approach 2:
The sawtooth profiles enable discrete parameter changes in height adjustment. By engaging different teeth of the sawtooth profiles, the bracket can be adjusted to various predetermined height positions, providing precision through standardized incremental changes rather than continuous adjustment.
2Ease of operation
If the end bracket allows relative movement between receiving angle element and fastening element, then ease of height adjustment is improved, but reliability of fixed position decreases
Solution Approach 1:
The end bracket transitions from a static fixed structure to a dynamic adjustable structure. The receiving angle element can move relative to the fastening element during adjustment, then locks into position when the adjustment element engages the sawtooth profiles, providing both ease of adjustment and reliability in the final position.
Solution Approach 2:
The height adjustment range is segmented into discrete positions defined by the sawtooth profile teeth. This segmentation allows easy adjustment to predetermined positions while ensuring reliable locking at each segment, as the adjustment element engages with individual teeth rather than requiring continuous positioning.
3Adaptability or versatility
If the end bracket is designed for versatile use with different module heights, then adaptability is improved, but device complexity increases
Solution Approach 1:
The end bracket is designed as a universal mounting solution that can accommodate different solar module heights. The combination of the receiving angle element with adjustable features and the fastening element with sawtooth profiles creates a single device that performs multiple height adjustment functions, eliminating the need for multiple specialized brackets.
4Reliability
If the adjustment element generates contact pressure on the solar module, then mounting reliability is improved, but ease of adjustment decreases
Solution Approach 1:
The adjustment element applies contact pressure in a periodic manner through the engagement of sawtooth profile teeth. As the adjustment element rotates, it periodically engages with the teeth, creating discrete adjustment steps. This periodic action allows easy incremental adjustment while maintaining reliable contact pressure when engaged.
