Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dent pullers for automobile metal sheets face issues such as the rarity of effective hand-operating devices due to design defects and the inconvenience of pneumatic pullers requiring constant electrical power and air compressor supply.
Innovation Solution
A hand/pneumatics dual operation vacuum pulling device that combines a hand-operating pump piston and a pneumatic operation seat, allowing easy switching between hand-operated and pneumatically-operated modes, featuring an elongate shank, slidable ram, suction cup, handgrip with pressure relief seat, and pneumatic pumping head, enabling both manual and air-powered suction with a T-shaped pneumatic configuration for efficient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pneumatic dent puller is used, then the suction force and pulling power is strong, but it requires constant electrical power supply and air compressor
Solution Approach 1:
The device incorporates a switchable operational mode system that dynamically transitions between pneumatic and hand-operated states. The handgrip can selectively couple with either a hand-operating pump piston or a pneumatic operation seat, allowing the system to adapt its power source based on availability of electrical power and operational requirements.
Solution Approach 2:
The handgrip serves as a universal interface that can accommodate multiple operational modes. It is designed to selectively couple with different components (hand-operating pump piston or pneumatic operation seat), enabling the same basic device structure to function in both pneumatic and manual modes, thereby eliminating the need for separate devices.
2Use of energy by moving object
If a hand-operating vacuum pulling device is used, then it does not require electrical power, but the suction force is weaker compared to pneumatic devices
Solution Approach 1:
The device incorporates a switchable operational mode system that dynamically transitions between pneumatic and hand-operated states. The handgrip can selectively couple with either a hand-operating pump piston or a pneumatic operation seat, allowing the system to adapt its power source based on availability of electrical power and operational requirements.
3Productivity
If a pneumatic dent puller is used, then the operation is efficient, but it is not easy to carry and requires air compressor
Solution Approach 1:
The handgrip serves as a universal interface that can accommodate multiple operational modes. It is designed to selectively couple with different components (hand-operating pump piston or pneumatic operation seat), enabling the same basic device structure to function in both pneumatic and manual modes, thereby eliminating the need for separate devices.
4Adaptability or versatility
If a dual operation device is designed, then it provides versatility and portability, but the device complexity increases
Solution Approach 1:
The device is divided into distinct modular components: the handgrip, the elongate shank with suction cup, and interchangeable operating mechanisms (hand-operating pump piston or pneumatic operation seat). This segmentation allows each component to be optimized independently and facilitates easy assembly, disassembly, and switching between modes.
Solution Approach 2:
The device incorporates a switchable operational mode system that dynamically transitions between pneumatic and hand-operated states. The handgrip can selectively couple with either a hand-operating pump piston or a pneumatic operation seat, allowing the system to adapt its power source based on availability of electrical power and operational requirements.

AI summary
A hand/pneumatics dual operation vacuum pulling device includes an elongate shank and a slidable backward ram fit to the shank. The shank has an end to which a suction cup is attached. The shank has an upper end to which a handgrip having a pressure relief seat is mounted. A ramp stop section is formed below the pressure relief seat. The handgrip can selectively and switchably couple with a hand-operating pump piston to form a hand-operating vacuum pulling device, or couple with a pneumatic operation seat to form a pneumatically-operating vacuum pulling device. For hand operation or pneumatics operation, the vacuum pulling device is allowed to easily switch between the two modes according to the availability of power supply and the site of use, thereby achieving an excellent device for one device having two ways of use.
