Wiper Accessory Clamp Structure for Secure Arm Movement
Solution Overview
Problem
Conventional wiper accessories prioritize ease of installation, leading to detachment during excessive arm movement, posing a safety hazard.
Innovation Solution
A wiper accessory design featuring a connecting body with elastic parts and clamping grooves that stabilize the wiper during assembly and disassembly, using pivot slots and clamps to secure the wiper to the arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wiper accessories emphasize ease of installation, then installation convenience is improved, but the wiper accessory may detach during excessive arm movement
Solution Approach 1:
The elastic part is designed to be deformable, allowing it to dynamically adapt between a clamping state (when arm movement is normal) and a release state (when arm movement exceeds the limit). This dynamic behavior enables the same structure to provide both easy installation and secure retention under excessive movement conditions.
Solution Approach 2:
The elastic part changes its physical state (deformation degree) based on the magnitude of arm movement. Under normal conditions, it maintains a clamping force for secure attachment; under excessive movement, it deforms to release the clamping force, allowing the wiper to detach safely rather than causing damage.
2Reliability
If the wiper accessory is designed to be secure during arm movement, then reliability is improved, but ease of installation may be compromised
Solution Approach 1:
The elastic part transitions between a clamping state (providing secure attachment) and a release state (allowing easy removal). The dynamic nature of the elastic deformation enables the structure to switch between secure and easy-to-install states without requiring complex mechanisms.
Solution Approach 2:
The elastic part automatically adjusts its clamping force based on the applied load. During installation, it naturally opens to allow insertion, then automatically clamps when the wiper is properly positioned, eliminating the need for separate locking actions.
3Ease of operation
If the clamp groove is designed to fully open for easy installation, then ease of operation is improved, but the wiper accessory may detach during excessive arm movement
Solution Approach 1:
The elastic part connected to the clamp groove dynamically adjusts the opening degree based on arm movement magnitude. During normal operation, it maintains sufficient clamping; during excessive movement, it deforms to allow the groove to open and release the wiper.
Solution Approach 2:
The physical state of the elastic part changes with the degree of arm movement, controlling the opening degree of the clamp groove. This parameter change enables the groove to transition between a closed clamping state and an open release state.
4Reliability
If the elastic part is designed to maintain constant clamping force, then reliability is improved, but the structure becomes complex
Solution Approach 1:
The elastic part automatically regulates its own clamping force through elastic deformation. It provides strong clamping under normal conditions and automatically releases under excessive movement, eliminating the need for external control mechanisms or complex regulation systems.

AI summary
A wiper structure is provided, including a wiper accessory (1), a wiper body (2), and an arm (3). The wiper accessory (1) features a connecting body (10) with an elastic part (11) located at one end and a pivot slot (100) situated beneath the connecting body. The wiper body (2) is equipped with an accessory base (20) that includes a pivot axle (21) pivotally connected to the pivot slot (100). The arm (3) includes a rod part (30) and a cover (31). The arm (3) is mounted on the wiper accessory (1). Clamping parts (12) are positioned on two sides of the connecting body (10), each featuring a hollow-shaped clamp groove (120) to clamp the accessory base (20). A lower edge (121) of each clamp groove (120) includes a flat portion and slopes downward towards the elastic part (11). Inner walls of the arm (3) include stop edges (311b) that abut the flat portions of the lower edges (121) to limit the arm (3) on the connecting body (10).
