Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of Hall sensors in high-voltage control boxes is hindered by the need for a fixed supporting surface and layout space, leading to increased weight, cost, and complexity, and the use of screws and ties complicates the assembly process.
Innovation Solution
A Hall sensor fixing member made of an elastic material with a through slot for inserting a metal piece, allowing for easy attachment and detachment by squeezing, and featuring a limiting portion to prevent sliding, thus eliminating the need for additional fixing components and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is used to fix the Hall sensor in the high-voltage control box, then the Hall sensor can be securely fixed, but the control box requires more layout space and has increased external dimensions
Solution Approach 1:
The fixing member is inserted into the mounting hole of the Hall sensor, with the metal piece inserted into the through slot of the fixing member. This nested structure allows the fixing mechanism to be integrated within the Hall sensor itself, eliminating the need for separate brackets and reducing the layout space required in the control box.
Solution Approach 2:
The fixing member utilizes the axial direction of the mounting hole for insertion and fixation. By transitioning from a lateral bracket attachment to an axial insertion through the mounting hole, the design reduces the space required in the planar layout of the control box while maintaining secure fixation.
2Reliability
If a bracket is used to fix the Hall sensor, then the sensor can be securely mounted, but the control box weight and cost increase
Solution Approach 1:
The fixing member combines multiple functions into a single component: it provides structural support for the Hall sensor, secures the metal piece through the through slot, and integrates with the mounting hole. This merging eliminates the need for separate brackets and additional fastening components, reducing overall weight.
Solution Approach 2:
The elastic material of the fixing member allows it to self-adjust and self-lock within the mounting hole through elastic deformation. The metal piece inserted into the through slot automatically secures the fixing member in place, eliminating the need for additional screws or ties, thereby reducing component count and weight.
3Reliability
If screws and ties are used to fix the Hall sensor on the bracket, then secure fixation is achieved, but the assembly process becomes more complex and operation more inconvenient
Solution Approach 1:
The elastic fixing member with the through slot allows the metal piece to be inserted directly, which automatically secures the fixing member in place through elastic deformation. This self-securing mechanism eliminates the need for screws, ties, or other fastening operations, making installation and disassembly simple and convenient.
Solution Approach 2:
The design extracts and eliminates the need for screws, ties, and complex fastening mechanisms from the assembly process. By using the elastic deformation of the fixing member and the insertion of the metal piece into the through slot, the system achieves secure fixation without additional fastening components or operations.
4Reliability
If a traditional bracket with supporting surface is used, then the Hall sensor can be fixed, but the control box external dimensions and manufacturing cost increase
Solution Approach 1:
The fixing member is designed as a universal component that can be applied to various Hall sensor models and control box configurations. The standardized structure with the through slot and elastic material provides a versatile solution that eliminates the need for custom-bracket designs, reducing manufacturing complexity and cost.
Solution Approach 2:
The fixing member integrates the supporting surface, fixation mechanism, and positioning features into a single component. This merging eliminates the need for separate brackets and supporting structures, simplifying the manufacturing process and reducing overall production costs.

AI summary
A Hall sensor fixing member, used for fixing a Hall sensor to a metal piece. A mounting hole into which the Hall sensor fixing member is inserted is formed in the Hall sensor. The Hall sensor fixing member is made of an elastic material. A through hole into which the metal piece is inserted is axially formed in the interior of the Hall sensor fixing member. The size of the through hole is less than the size of the metal piece. When the metal piece is inserted into the through hole by squeezing, the Hall sensor fixing member is elastically deformed and expands outward under the action of squeezing by the metal piece, such that the outer wall of the Hall sensor fixing member and the inner wall of the mounting hole of the Hall sensor abut against to each other and are thus fixed.
