Scanner Holding Bracket Structure to Prevent Rattling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching a holding bracket to a scanner frame using screws result in cutting powder generation and rattling, which can affect the performance and increase production costs, and the existing methods do not effectively address the issue of securely attaching the bracket to the scanner frame, which can affect the reading performance of the scanner.
Innovation Solution
A holding bracket with an insertion portion and multiple abutments is used to attach to a scanner frame without screws, ensuring secure attachment and preventing rattling, thus maintaining reading performance and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to attach the holding bracket to the scanner frame, then the bracket can be securely attached, but cutting powder is generated and rattling occurs which affects performance and increases production costs
Solution Approach 1:
The patent removes the screw fastening mechanism from the attachment system. Instead of using screws that generate cutting powder and rattling, the invention uses a bracket body with an insertion portion that fits into a through hole and abutments that contact the scanner frame, eliminating the harmful factors associated with screw-based attachment.
Solution Approach 2:
The patent replaces the traditional screw-threaded mechanical fastening system with a different mechanical system based on insertion and abutment contact. The bracket body inserts through a through hole and is secured by abutments contacting the scanner frame, substituting the harmful screw mechanism with a cleaner insertion-based mechanism.
2Reliability
If screws are used to attach the holding bracket, then attachment is achieved, but production costs increase due to additional manufacturing steps
Solution Approach 1:
The patent eliminates the screw fastening mechanism and its associated manufacturing steps (drilling, tapping, screw installation). The simplified design uses a bracket body with an insertion portion that fits into a through hole and is secured by abutments, reducing manufacturing complexity and cost.
Solution Approach 2:
The patent transitions from a multi-step screw fastening process to a single-step insertion process. The bracket body is inserted through a through hole and secured by abutment contact, eliminating the need for separate screw installation steps and reducing production time and cost.
3Ease of manufacture
If a simple attachment method is used, then production costs are reduced, but the bracket may not be securely attached affecting reading performance
Solution Approach 1:
The patent divides the attachment function into distinct components: an insertion portion for passing through the through hole, abutments for contacting the scanner frame, and a bracket body for structural support. This segmentation allows each component to perform its specific function effectively, ensuring secure attachment without complex mechanisms.
Solution Approach 2:
The patent uses curved or rounded surfaces in the abutment design to distribute contact forces and improve attachment security. The abutments are designed to contact the scanner frame at optimal points, using surface geometry to enhance the reliability of the attachment while maintaining manufacturing simplicity.

AI summary
A holding bracket includes a terminal mount, an insertion portion, a first abutment, and a second abutment. A connection terminal is mounted to the terminal mount. The insertion portion is inserted into a through hole of the fixed member in an insertion direction from an outer face to an inner face of the fixed member. The first abutment is disposed at a tip of the insertion portion to abut against the inner face of the fixed member. The second abutment abuts against the outer face of the fixed member. An abutment of the first abutment and the second abutment against the fixed member attaches the holding bracket to the fixed member.
