Hedge Trimmer Chip Receiver Flat Base Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hedge trimmers suffer from branches and leaves scattering on the ground due to protruding parts on the chip receiver's upper surface, which interrupts the cut material from entering the receiving part.
Innovation Solution
A hedge trimmer design with a flat upper surface on the chip receiver's base part, eliminating any protruding elements that could interfere with cut branches and leaves, allowing them to enter the receiving part without scattering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protruding part is disposed on the upper surface of the base part of the chip receiver, then the structure provides engagement features for attachment, but the protruding part interrupts branches and leaves from entering the receiving part, causing them to scatter on the ground
Solution Approach 1:
The invention extracts the harmful protruding part from the upper surface of the base part. By removing the protruding part that was interrupting the flow of cut material, the design eliminates the scattering problem while maintaining attachment functionality through alternative means such as engagement parts on the side surfaces of the fixed plate
Solution Approach 2:
The invention moves the engagement features from the upper surface (vertical dimension) to the side surfaces (horizontal dimension) of the fixed plate. This dimensional relocation allows the attachment mechanism to function without interfering with the vertical flow of branches and leaves into the receiving part
2Object-generated harmful factors
If the upper surface of the base part is made flat, then branches and leaves can enter the receiving part without interruption, but the attachment mechanism becomes more complex requiring engagement parts on side surfaces
Solution Approach 1:
The invention segments the attachment mechanism into separate engagement parts positioned on the left and right side surfaces of the fixed plate. This segmentation allows the attachment function to be distributed across multiple locations that do not interfere with the central flow path of cut material into the receiving part

AI summary
A hedge trimmer may include a body housing, a fixed plate, a blade and a chip receiver. A first engaged part may be disposed on a first side surface of the fixed plate and a second engaged part may be disposed on a second side surface of the fixed plate. The chip receiver may include a base part mounted on the fixed plate, a receiving part and an attachment part. The attachment part may include first engaging part, a second engaging part configured to be movable between an engaging position and a non-engaging position, and a manipulation part configured to move the second engaging part from the engaging position to the non-engaging position in response to a user operation. An upper surface of the base part is flat.
