Adjustable Handle Body Fat Scale for Accurate Palm Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body fat scales with fixed handles cannot accommodate varying hand sizes, leading to inaccurate measurements due to mismatches between the handle length and the user's palm size, particularly between children and adults.
Innovation Solution
A body fat scale with a handle that includes telescopic bases allowing adjustable length, comprising a fixed base and two telescopic bases that can extend or retract, ensuring the handle length can be customized to fit different user sizes by sliding and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the handle length is fixed, then the device structure is simple, but the measurement precision deteriorates due to mismatch with different palm sizes
Solution Approach 1:
The handle is designed with telescopic bases that allow dynamic adjustment of length. The first and second telescopic bases can extend or retract along the length direction of the fixed base, enabling the handle to adapt to different palm sizes while maintaining measurement accuracy.
Solution Approach 2:
The handle is divided into multiple segments: a fixed base and two telescopic bases. Each telescopic base consists of multiple housings (first left housing, second left housing, first right housing, second right housing) that can slide relative to each other, allowing independent adjustment of handle length segments.
2Adaptability or versatility
If the handle length is adjustable, then the adaptability improves for different users, but the device complexity increases
Solution Approach 1:
The telescopic bases provide dynamic adjustability where the first and second telescopic bases can extend or retract along the length direction of the fixed base, allowing the handle to adapt to different palm sizes of users.
Solution Approach 2:
The telescopic bases use a nested structure where the first left housing and second left housing are connected through a first detachable structure, and similarly for the right side. The housings are nested within each other and can slide along the length direction, enabling compact storage when retracted and extended length when needed.
3Ease of operation
If telescopic bases are added to adjust handle length, then the ease of operation improves, but the manufacturing complexity increases
Solution Approach 1:
The telescopic bases enable easy adjustment of handle length by allowing the first and second telescopic bases to extend or retract along the length direction of the fixed base, making the device adaptable to different user needs.
Solution Approach 2:
The sliding structures are pre-configured during manufacturing with guide rails and sliding blocks positioned to enable smooth extension and retraction of the telescopic bases. The locking structures are pre-positioned to automatically engage at predetermined lengths, simplifying the user operation.
4Reliability
If locking structures are implemented to maintain telescopic base position, then the reliability improves, but the device complexity increases
Solution Approach 1:
The locking structures work in conjunction with the telescopic bases to provide stable positioning. The first locking structure includes a first clamping groove formed in the first telescopic base and a first hook disposed on the fixed base, enabling reliable locking at extended or retracted positions.
Solution Approach 2:
The locking structures are designed to automatically engage when the telescopic bases are extended or retracted to predetermined positions. The hooks clamp into the clamping grooves without requiring additional manual intervention, providing self-locking functionality that maintains reliability while minimizing operational complexity.

AI summary
The present invention discloses a body fat scale, including a scale body and a handle electrically connected to the scale body, where the handle includes a fixed base, a first telescopic base slidably disposed on one side of the fixed base, and a second telescopic base slidably disposed on the other side of the fixed base, and the first telescopic base and the second telescopic base may extend or retract along a length direction of the fixed base, to change a length of the handle. According to the above structure, the length of the handle can be adjusted according to a size of a palm of a user, so that the user can measure body fat at an optimal length, and the body fat and other parameters can be measured more accurately.
