Handheld Garden Tool Battery-Control Layout for Compact Detachable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld electric tools with battery power sources have a large structure due to restrictive ejection structures, leading to inconvenient use, especially in outdoor environments.
Innovation Solution
A handheld garden tool design featuring a housing with an accommodation space for a control member and a detachable battery pack, where the control member's projection overlaps the battery pack's projection, with connection structures such as protrusions and recesses for a compact and stable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control member is disposed in the battery pack according to existing ejection structures, then the battery pack can be detachably connected, but the volume of the entire structure becomes relatively large and use becomes inconvenient
Solution Approach 1:
The control member is nested within the battery pack structure, with its projection overlapping the battery pack's projection in the left and right direction. This nesting arrangement allows the control member to be integrated into the battery pack's volume rather than adding to it, reducing the overall structure volume while maintaining ease of operation.
Solution Approach 2:
The control member is positioned in the front-rear direction within the battery pack, with its projection in the left-right direction overlapping the battery pack's projection. This spatial arrangement in multiple dimensions optimizes the use of available space, reducing the structure's volume footprint while keeping the control member accessible for operation.
2Volume of moving object
If the control member is disposed in the housing accommodation space, then the structure becomes more compact, but the connection between battery pack and housing must be stable
Solution Approach 1:
The first connection structure on the housing and the second connection structure on the battery pack are designed to work together as an integrated connection system. The protrusion-recess configuration merges the connection functions into a unified structure that provides stable attachment while allowing the control member to be positioned in the housing accommodation space for compactness.
Solution Approach 2:
The connection structures use asymmetric protrusion and recess configurations, where the protrusion on one component fits into the corresponding recess on the other component. This asymmetric design ensures stable and reliable connection between the housing and battery pack while enabling compact arrangement of internal components including the control member.

AI summary
A handheld garden tool includes a housing, a control member, and a battery pack. The housing extends in the front and rear direction and is formed with an accommodation space. The control member is at least partially disposed in the accommodation space. The battery pack is detachably connected to the housing. In a projection plane perpendicular to the left and right direction, the projection of the control member in the projection plane in the left and right direction is a first projection, and the projection of the battery pack in the projection plane in the left and right direction is a second projection. The first projection at least partially overlaps the second projection.
